- Every benchmark records ≥1 non-`tileops` baseline. If the external baseline is conditional, add a local torch fallback.
- Tag names: lowercase, hyphen-separated. Tags starting with `tileops` are TileOPs entries; everything else is a baseline.
- `calculate_flops()` / `calculate_memory()` return `None` to omit the metric.
- Benchmark shapes reflect real DNN workloads (LLaMA-family by default). Annotate shape constants with the model/scenario; never use arbitrary flat numbers (262K, 1M, 4M).

- When a reviewer asks to add implementation detail (e.g. "list the current files"), push back unless the design itself changed. Test: would this wording survive the next 5 implementations?

## Boundary
- **OWNS**: `tileops/manifest/`
- **MUST NOT WRITE**: `tileops/ops/`, `tileops/kernels/`, `tests/`, `benchmarks/`
- Manifest changes require human review in a separate PR.
→ [trust-model.md §Manifest](../../docs/design/trust-model.md#manifest)
______________________________________________________________________
- Manifest key must equal the Op `cls.__name__` exactly. Class-naming convention: see [ops-design.md](ops-design.md).
- `ref_api` (required): the external API the signature mirrors (e.g. `torch.nn.functional.rms_norm`); `"none"` if none. Validator enforces presence + string type only; semantics not checked.
- `inputs`, `outputs`, `params` are ordered dicts — key order is signature position. Don't reorder.
- Op signatures must match PyTorch's public API (names, set, semantics); include every supported parameter even if the kernel only honors the default. Default to `__init__` kwargs (lifetime-fixed); use `forward()` only when the reference API requires it or the value is per-batch — justify in the introducing issue.
- `dtype` syntax: `|` for alternatives. `same_as(ref)` is dtype-only identity (matches `ref` at runtime, no extra axis in `dtype_combos`, never used for shape).
- `dtype_combos` only when the supported set is a strict subset of the Cartesian product. Omit when all combinations are valid.
- Output shapes are fully specified by `shape` and/or `shape_rules`. `shape` present → fixed rank, names become roofline variables; `shape` absent on inputs → arbitrary rank, use `params` + `shape_rules`. Shared dim names across tensors → sizes must match.
- `shape_rules` are Python expressions describing shape relationships. For reduction-dim validation, use the canonical predicates / extractors in `tileops.manifest.shape_rules` (callable by bare name from any rule body); never silently wrap out-of-range indices with `% x.ndim`. Inline string expressions are a transitional fallback only.
- **Reduction `dim` authoring contract.** When `dim` accepts an integer or a sequence (`list[int]` / `tuple[int, ...]`), declare three `shape_rules` in this order:
1. **Range validity.** Every axis in `[-x.ndim, x.ndim)`. For ops accepting `None`: `"dim is None or all(-x.ndim <= d < x.ndim for d in ([dim] if isinstance(dim, int) else dim))"`. Drop the `dim is None or` prefix when the op does not accept `None`.
1. **Normalize negatives.** Downstream rules apply `% x.ndim` only after step 1, producing the canonical axis set `{d % x.ndim for d in dim}`.
1. **Uniqueness (sequence only).** `"isinstance(dim, (int, type(None))) or len({d % x.ndim for d in dim}) == len(dim)"`.
Empty-sequence semantics is per-op:
- Ops accepting `dim=None` (`sum`, `mean`, `amax`, `amin`, `var`, `std`, `var_mean`, `all`, `any`, `count_nonzero`, `linalg.vector_norm` variants): empty sequence ≡ full reduction; formulas use `set(range(x.ndim))` as fallback.
- Ops without `dim=None` (e.g. `logsumexp`): empty sequence is invalid; declare `"isinstance(dim, int) or len(dim) > 0"`.
- Roofline `vars` maps variable names to Python expressions over tensor shapes and params. Required for arbitrary-rank ops.
- `status` is required: `implemented` or `spec-only`.
- `torch_compile_fullgraph`: literal `true` only; omit for no promise; invalid on `spec-only`. Declare only ops with a registered cold `fullgraph=True` compile test. Semantics: [manifest.md](../../docs/design/manifest.md#torch_compile_fullgraph).
- No `Optional[Tensor]` in manifest. Conditional inputs split into variant entries linked by `variant_of` (single-level, no chaining). Variants share `source.kernel` and `source.op`; each carries its own `signature`, `workloads`, `roofline`.
- Tensor layout defaults to contiguous row-major. Non-default needs an explicit `layout` field; `shape` dim names reflect memory order.
- `source.kernel_map` is the Op→Kernel dispatch registration table (`dispatch_key: KernelClassName`). It declares what an Op uses, not how dispatch picks.
- Never modify manifest to match non-conforming code. Code drift → `status: spec-only` and fix code in a follow-up PR. Never remove `params`, roofline `vars`, or `shape_rules` to silence validator errors.
- `ref_api` is the spec oracle for the manifest signature, not an Op-layer dispatch target at forward time.
- **Manifest comment policy.** Comments may carry technical content the DSL can't express (schema clarifications, edge cases, conventions, file headers); they MUST NOT carry process metadata bound to a specific issue, PR, commit, or round. Keep only if meaningful after every issue/PR is renumbered; otherwise move to commit message, PR description, or follow-up issue.

- Validator failures mean the op, manifest, or benchmark is wrong — **not** the validator. Do not edit validator code, downgrade errors to warnings, add skip paths, or special-case a new op to get CI green.
- Manifest-key match is direct string equality on `cls.__name__`. Do not add normalization, casing fallbacks, or alias paths.
- Validator-related infrastructure: `scripts/validate_manifest.py`, `tests/test_validate_manifest.py`, `docs/design/manifest.md`. Only modify these when the PR is explicitly about manifest schema, trust-model policy, or validator infrastructure — and document the change in the PR body.
- If a new op cannot satisfy the current validator: stop and surface the mismatch. Do not "fix" it in the validator.

______________________________________________________________________
- Class names: PascalCase `{Name}{Direction}Op` (Op layer) or `{Name}{Direction}Kernel` (Kernel layer); direction suffix mandatory. Manifest author chooses `{Name}`. Builder functions stay snake_case.
- `kernel_map` is the Op→Kernel dispatch registration table: snake_case dispatch keys (decoupled from class names) → Kernel class names. Manifest declares it; agents implement the listed Kernels. See [ops-design-reference.md § Kernel Dispatch](../../docs/design/ops-design-reference.md#kernel-dispatch-kernel_map).
- Op `__init__` is keyword-only (`def __init__(self, *, ...)`). Parameter names come from the manifest: `shape` dim names (fixed-rank), `static_dims` keys (arbitrary-rank), `params` keys. Only manifest-declared information belongs in `__init__`.
- Arbitrary-rank ops declare construction-time values via manifest `static_dims`. Each entry is a single-axis reference `<tensor>.shape[<const_or_param>]`; other dims come from tensors at forward time. See [manifest.md R20](../../docs/design/manifest.md).
- Update `docs/design/ops-design.md` whenever you add/modify an intermediate base class, change a kernel-dispatch pattern, or introduce a new class-variable protocol.
- A new op family inheriting `Op` directly: first check whether an existing family's `forward()` flow already fits before creating a new base class. Record the decision in the PR.
- Per-op workarounds MUST NOT be promoted to a base-class shared mechanism (mixin, class attribute, shared method, opt-out flag) within the same op-family migration PR — even when multiple ops share the workaround. Promote only via a separate design PR that shows the mechanism is a genuine family invariant (would belong in the base even if no op had taken a shortcut), not a shared shortcut.
- PyTorch fallback at forward time is permitted only when TileLang cannot express the operation at the required shape AND no closed-form replacement exists in tensor primitives; document the call site with the blocking limitation and a tracking issue. Helper conveniences (`x.float().mean(...)` for clarity) are out of scope — the rule targets full-operator delegation.
- Inline roofline state contract: for every `signature.inputs` / `signature.params` name **referenced** by the op's manifest `roofline` expressions, the op exposes it on `self`. Inputs: `self.<input>` with `.shape` and `.ndim`, OR `self.<input>_shape` as a shape tuple/list. Params: `self.<param>`. Unreferenced names need not be exposed. See [docs/design/roofline.md §4.4.3](../../docs/design/roofline.md).
- Dynamo-traced `forward` MUST NOT construct a `Kernel` or enter a TileLang builder; call-time kernel resolution goes through the compile dispatch boundary. See [ops-design.md](../../docs/design/ops-design.md#compile-dispatch-boundary).

- Every test case traces to a specific code path, dtype dispatch, or regression. No cases for combinatorial confidence.
- Test all supported dtypes. Don't cross dtype and shape coverage unless the combination triggers a distinct code path.
- Don't generate fixtures from `tileops/manifest/` workloads. Test parameters are a curated correctness subset.
- Before committing: drop scaffolding tests that guarded intermediate implementation steps and don't guard any final code path.
- Run `scripts/test_node_delta.py` on PRs touching test files. Growth on existing files → include the script output + a one-line justification in the PR body. New test files only → no delta report.
- Binary-op tests cover broadcast semantics: bias-add `(B,S,D)+(1,1,D)`, row `(B,S,D)+(B,S,1)`, scalar `(M,N)+(1,1)`. Applies to arithmetic, comparison, logical, bitwise.
- Skill development tests stay local — never commit anything under `.claude/skills/`.

Run before approving any PR. Apply each item if its scope matches the diff. If any applicable check fails, REQUEST_CHANGES until the developer pushes a triage commit.
## Tests
- [ ] **Per-case verdict.** Triage every added/modified test case as `keep` / `shrink` / `delete`. Inline only on blockers; clean test PRs stay clean (`criteria.md §3`).
| Verdict | When | Inline? |
| ------------------------------ | ---------------------------------------------------------------------------- | ----------- |
| `keep — guards <path/dtype>` | distinct code path or dtype (per `docs/design/testing.md §Test case policy`) | no |
| `shrink — fold to <axis>` | Cartesian expansion; fold to "boundary + one representative interior point" | **blocker** |
| `delete — duplicate of <node>` | same-failure-mode duplicate of a kept case | **blocker** |
Cases the reviewer cannot classify with confidence count as untriaged → **blocker inline** asking the developer for rationale. Every blocker must be resolved (shrink / delete, or downgrade to `keep` with rationale) before APPROVE.
- [ ] **Numerical floor.** Run `python scripts/test_node_delta.py --base upstream/main` (prereq: `upstream` points to tile-ai/TileOPs and is fresh — `git fetch upstream` first). REQUEST_CHANGES with the full node-ID list if existing-file growth > 25% AND any case carries an unresolved `shrink`/`delete` blocker or is untriaged. Absence of an inline is not itself a blocker — silent `keep` is the default.
- [ ] **Critical-path floor.** Never remove the last test on an output-distinguishing input: tile boundary, vectorization alignment, degenerate dimension (size = 1), or a dispatch branch carrying observable behavior. Tests with no output-distinguishing input are removable.
- [ ] **No AC defense.** Reject "AC-N required this matrix" — AC text does not bind the merged suite.
## Authoring discipline
- [ ] **PR body.** Conforms to `.foundry/mold/pr-body-template.md`; records final state only — what the PR does (Summary, scoped to the merged diff) + verification facts (test plan, pre-commit, structural readiness, test node delta). Strip dev-process narration: per-round fix history, tally IDs (`T001–T0NN`), "Driven by review iteration", reviewer-by-reviewer changelogs, abandoned approaches. Those belong in commit history / review threads. REQUEST_CHANGES if found.
- [ ] **Replies.** Outcome only — `Done in <sha>.`, `Won't-fix: <one-line reason>.` No commit-by-commit narration, "what I tried", thread/tally IDs, root-cause essays, or design restatements. Process detail ages out and clutters the thread. REQUEST_CHANGES asking the developer to edit the comment to a one-liner if found.
## Review process
- [ ] **Batch-once.** If only cleanup-class issues (keep / shrink / delete / rename / dedupe) remain with no correctness blockers, surface every such item from the full diff in this single pass. Don't defer — either include now or demote to advisory (no longer gates APPROVE).
- [ ] **Re-run on triage.** Re-run every applicable check above on the developer's triage commit before approving.
## Scope-specific
- [ ] **Skill edits (`.claude/skills/**`).** Require a tightening pass before APPROVE — condense wording without changing what the skill instructs. Verify: semantics preserved, every step has exactly one valid execution path, no example included unless load-bearing, retained examples reference durable concepts rather than implementation details that age out.

For `[Bench]` PRs. Benchmarks live downstream of every other layer and must never silently substitute for tests or for the manifest.
Load `.claude/domain-rules/benchmark.md` before reviewing.
Two non-negotiable principles cut across every event:
- **Independent baselines.** Every benchmark must record at least one non-`"tileops"` baseline (PyTorch, vendor, third-party kernel). A benchmark that only times TileOps against TileOps is a self-comparison, not a benchmark — reject it.
- **No correctness assertions.** Benchmarks measure performance; they do not gate behavior. `assert torch.allclose(...)` and equivalents belong in `tests/`. A correctness check inside `benchmarks/` is a trust-layer violation regardless of how convenient it is.
#### Checklist
- [ ] **Boundary respected.** Diff stays inside `benchmarks/`. No edits to `tileops/ops/`, `tileops/kernels/`, `tests/`, `workloads/`, or `tileops/manifest/` (`.claude/domain-rules/benchmark.md §Boundary`).
- [ ] **Independent baseline present.** Each new/edited benchmark records ≥1 non-`"tileops"` baseline. If the external baseline is conditional, a local torch fallback is registered.
- [ ] **No correctness gating.** No `assert`, `torch.allclose`, or equivalent inside `benchmarks/`. Numeric mismatches surface through report columns, not exceptions.
- [ ] **Realistic shapes.** Shape constants reflect real DNN workloads (LLaMA-family or equivalent), annotated with the model/scenario they represent. Arbitrary flat numbers (e.g., 262K, 1M, 4M) are rejected.
- [ ] **Tag and FLOPs/memory hygiene.** Tags are lowercase hyphen-separated; `"tileops"`-prefixed tags are TileOps entries, all others are baselines. `calculate_flops()` / `calculate_memory()` return numeric or `None` consistently.
- [ ] **`record()` arg style consistent.** Within one file, `BenchmarkReport.record()` uses Op object (preferred) or string name uniformly — no mid-file flips.

For `[Doc]` and `[Design]`.
A flag in this domain names one of: a contradiction (cite file:line on both sides), a missing follow-up reference, a scope violation (quote the offending line), or a re-introduced removal (cite the prior commit).
#### Design docs (`docs/design/*.md`)
TileOps is a design-first project. Design docs guide agent development; tight scope keeps agents on top-level decisions instead of mechanics. Also load `.claude/domain-rules/design-docs.md`.
- [ ] **Top-level only.** Content is a target convention, module boundary, or contract. Reject added codebase mechanics, file enumerations, or implementation snapshots.
- [ ] **No contradictions.** Cross-check against neighboring design docs and `tileops/manifest/`. Flag conflicting MUST / SHOULD with file:line on both sides.
- [ ] **Concise.** Flag content that does not constrain the decision — history narration, illustrative examples, rationale that doesn't explain a choice.
- [ ] **Drift-free.** If the doc states a target the code or manifest doesn't satisfy, the PR includes the change or links a follow-up issue.
#### Other docs
Covers READMEs, `CLAUDE.md` family, agent-facing skill docs, and source comments. Lighter bar — only consistency and drift matter.
- [ ] **No contradictions** with current code, manifest, or design docs. Cite file:line on both sides.
- [ ] **Drift-free.** Implied code or manifest change is included in the PR or linked as a follow-up issue.

#### Checklist
- [ ] Op/kernel public interface matches its `tileops/manifest/` entry. No entry → wrong PR order
- [ ] Manifest edits, if any, stay within the carve-out whitelist (`.claude/rules/manifest-trust-model.md`)
- [ ] If feature is an op, spot-check the diff against at least one of the structural checks below; flag any divergence (full rules in `docs/design/ops-design-reference.md`):
- Class name ≡ manifest entry key
- `__init__` kwargs derivable from manifest (`static_dims` / `dtype` / `signature.params`)
- `default_kernel_map` matches `source.kernel_map` verbatim
- `forward` validation order: `_validate_dtypes` → shape rules → `static_dims` commitment → kernel call
- `_validate_dtypes` matches manifest `dtype` / `dtype_combos`
- `eval_roofline` is a plain-Python body (no class-level expression strings, no `ast.parse`)

For `[Maintain]`, `[Refactor][Manifest]`, and any PR that flips a manifest entry's `status`. The manifest is the authoritative spec for op interfaces — every check below exists to keep that authority real.
Load `.claude/domain-rules/manifest-spec.md` before reviewing.
Two non-negotiable principles cut across every event:
- **Reference semantic alignment.** Any change to an op's spec (signature, shape rules, dtype combos, roofline vars) must map back to an authoritative reference — PyTorch public API for `torch.nn.*` / `torch.nn.functional.*` names; the paper or vendor docs otherwise. Reverse-engineering from current TileOps code is forbidden — spec is upstream of code.
- **`status` field truthfulness.** `status: implemented` is a hard claim that code conforms to the entry. The reviewer's job is to *disprove* it, not to take it on faith. Status flips that don't reflect actual conformance corrupt the trust model.
#### Add-manifest (new entry)
PRs from the `add-manifest` skill, or any PR that adds a previously-absent op entry.
- [ ] **Reference cited and authoritative.** Entry's `source` field points to PyTorch / paper / vendor docs. Reviewer can derive shape and dtype rules from that link alone.
- [ ] **Signature matches reference exactly.** For `torch.nn.*` / `torch.nn.functional.*` names: parameter names, order, and defaults all match PyTorch's public API. No invented parameters.
- [ ] **Required fields present.** `signature`, `shape_rules`, `dtype_combos`, `roofline`; `kernel_map` and `static_dims` where the family requires them.
- [ ] **Lands as `spec-only`.** New entries never land as `implemented`, regardless of any existing code claiming to be ready.
- [ ] **Validator green.** `scripts/validate_manifest.py` passes with no checks disabled.
- [ ] **No code change.** Diff does not modify `tileops/ops/` or `tileops/kernels/`.
#### Fix-manifest (patch existing entry)
PRs from the `fix-manifest` skill — patches one missing structural field (`kernel_map`, `static_dims`) on an existing entry.
- [ ] **Scope is one structural field.** Diff modifies exactly one missing field. Edits to `signature`, `shape_rules`, `dtype_combos`, or `roofline` belong to `add-manifest`, not `fix-manifest` — reject and split.
- [ ] **Reference still aligns.** Other reference-derivable fields (`signature`, `shape_rules`, `dtype_combos`) on the same entry have not silently drifted from the source URL. Spot-check at least one.
- [ ] **Validator green.**
- [ ] **No code change.** Diff does not modify `tileops/ops/` or `tileops/kernels/`.
#### Status flip (`spec-only` ↔ `implemented`)
Often bundled with a `[Refactor][Ops]` op-migration PR.
- [ ] **Conformance verified, not asserted.** Reviewer diffs the op's `__init__` and `forward` against the manifest entry field-by-field — names, types, defaults, shapes.
- [ ] **Spec tests actually run.** No `pytest.skip`, `xfail`, or weakened assertion left from the `spec-only` era. Grep the test file before approving.
- [ ] **`FIXME(staged-rollout)` markers tied to this op removed.**
- [ ] **Flip back to `spec-only`** is legitimate only when implementation is removed or known-broken. Challenge any other rationale.
- [ ] **Pure flip.** This PR changes `status` only — no rewrite of `signature` / `shape_rules` / `roofline`. If the entry needs spec edits to match implementation, that is reverse-engineering from code; reject and require a separate `add-manifest`- or `fix-manifest`-style PR.
- [ ] **`source.kernel_map` present.** `status: implemented` requires the Op→Kernel dispatch map. The validator currently emits a *warning* for missing `kernel_map`; the human reviewer escalates that to a blocker on a flipped entry.
- [ ] **`workloads` non-empty and tensor-input shapes complete.** `status: implemented` requires at least 2 workloads (`test_every_op_has_at_least_two_workloads`). Each row must declare a shape for *every* tensor input in `signature.inputs` — `input_shape` alone is not enough when the op has additional tensor inputs (e.g. `mask_shape`, `value_shape: []`, `min_shape`, `max_shape`). Empty `workloads: []` or a row missing any required tensor-input shape on a flipped entry is a blocker — copy from the sibling variant or derive from the op's typical usage shapes.

Common rules for every checklist in this folder. Load before any title-specific checklist.
## Load order
1. `docs/design/trust-model.md` — stage contracts (`manifest → test → implementation → benchmark`).
1. The title-specific checklist.
## Review lens
Apply trust-model rules as a review lens: surface cross-layer diffs as comments with a concrete citation; the author replies with rationale; the reviewer judges on content. Provenance labels (`automated` / `needs-review` / `nightshift`) record origin; review criteria apply uniformly.
## Cross-layer review criteria
| Criterion | Pass | Fail |
| ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------- |
| Oracle origin | `ref_program` resolves to PyTorch / NumPy / closed-form / IEEE-754 | Agent-fabricated literal as expected value |
| Coverage set | Unchanged or strictly expanded; deletions target code paths the same diff removes | dtype / shape / sign cells removed with the code path still present |
| New-path coverage | A test reaches each diff-added code path on an input that makes its output differ from the alternative. Aliases (paths with no output-distinguishing input) are exempt. | A diff-added path's output-distinguishing input has no test |
Cite the failing criterion by name.
## Comment quality
| Rule | Required form |
| ---------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| Concrete pointer | `file:line`, entry path, field name, parametrize axis, ref URL, test name, or the offending diff line |
| Decidable claim | A concrete claim about that pointer. Hedged forms ("looks reasonable", "may want to verify", "consider revising", "could be clearer") fail this rule |
| Suggestion scope | Suggestions stay within fixes for flagged items |
## Scope
Checklists are the floor. Add PR-specific checks when the diff warrants them.

For `[Refactor]`.
#### Checklist
- [ ] Any `xfail` / `skip` / loosened assertion has a `FIXME(staged-rollout)` block per `.claude/rules/code-style.md`
- [ ] If the op has a manifest entry, signature still matches it
- [ ] **Trust-layer scope.** Refactor stays within one trust layer per `docs/design/trust-model.md` (manifest / test (incl. `workloads/`) / implementation / benchmark). Cross-layer touches are judged by `pre-review.md` criteria (oracle origin, coverage set, new-path coverage).
#### Sub-types
- `[Refactor][Manifest]` → load `manifest.md` instead. `tileops/ops/` and `tileops/kernels/` must NOT change in the same PR.
- `[Refactor][Ops]` / `[Refactor][<Family>]` that flips `status` → also load `manifest.md`.

- For the OWNS / boundary chart of the manifest stage, see [docs/design/trust-model.md](../../docs/design/trust-model.md) §Manifest.
- When the op name matches a PyTorch op (`torch.nn.*`, `torch.nn.functional.*`), the manifest signature must match PyTorch's public API. Do not invent parameters.
- Implementation does not conform to spec → set `status: spec-only`, fix code in follow-up PR. Never modify manifest to match code.
- Do not remove `roofline.vars`, `shape_rules`, or `params` to silence validator errors.
## Status flip carve-out
An implementation PR may edit the aligned op's manifest entry only at:
- `status` (any direction).
- `source.kernel_map` entries.
- `source.test` and `source.bench` path values. Discoverability pointers, not contractual fields — may be retargeted at the per-op test/bench file authored by the same PR.
- `workloads` — **only** when the same PR flips `status: spec-only → implemented` on that op (promotion forces non-empty workloads to satisfy `test_every_op_has_at_least_two_workloads`).
- `torch_compile_fullgraph` — **only** together with its registered compile-test evidence.
Every other field — `family`, `ref_api`, `signature`, `roofline.*`, `params`, `output-dtype`, `shape_rules`, `source.kernel`, `source.op`, `source.bench_manifest_driven`, and any other `workloads` edit — needs a separate manifest-only PR with human review.
The carve-out narrows the prohibition; it does not relax the trust boundary.

name: add-manifest
description: Generate or re-align one `tileops/manifest/` entry from a reference-API docs URL. Caller provides the manifest key (`op_name`); skill writes that one entry. Idempotent.
---
## Arguments
| Argument | Required | Description |
| --------- | -------- | ----------------------------------------------------------------------------------------------------------------------- |
| `op_name` | Yes | Manifest key (e.g., `RMSNormFwdOp`). Caller-supplied, never derived. For variants, caller invokes once per emitted key. |
| `ref_url` | Yes | HTTPS docs URL for the Tensor op. Must match `^https://[A-Za-z0-9./_-]+\.html$`. |
## Contract
**One entry per invocation.** No splitting, no variant orchestration. For primary + variant, caller invokes the skill twice with different `op_name`s.
**Idempotent.** Auto-derivable fields are rewritten from the reference; human-curated fields are preserved if the entry exists, defaulted otherwise.
| Auto-derivable (always rewritten from reference) | Human-curated (preserved if entry exists, else default) |
| ------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------- |
| `signature.{inputs,outputs,params}` | `family` (default: from sibling-entry copy or BLOCKED) |
| `signature.shape_rules` | `ref_api` (default: derived from `ref_url`'s last path segment) |
| `signature.dtype_combos` | `workloads` (default: `[]`) |
| `roofline.{flops,bytes,vars}` (well-known op) | `source.{kernel,op,test,bench,kernel_map,bench_manifest_driven}` (default: from RESOLVE_SOURCES + `bench_manifest_driven: false`) |
| | `status` (default: `spec-only`) |
| | Adjacent comments (best-effort) |
**Termination**: draft PR created → success. Invalid URL / un-derivable roofline / source-path or family resolution failure → BLOCKED.
**Constraints**: never edit op / kernel / test / bench code. Never invent params outside the reference. Never set `status: implemented` (that is `align-op@FLIP_STATUS`).
**File to edit**: write the entry into `tileops/manifest/<family>.yaml`, where `<family>` is the entry's `family` field. The manifest is split one file per family; do not create new files or move entries between files. Use `ruamel.yaml` for round-trip preservation of comments and key order.
**Caller responsibility**: `op_name` and `ref_url` must point at the same op. The skill does not enforce alignment between them — TileOPs identity may legitimately differ from any reference's naming (e.g., `MultiHeadAttentionFwdOp` ↔ `torch.nn.functional.scaled_dot_product_attention`). Wrong pairing produces a broken manifest entry silently.
## Workflow
```mermaid
stateDiagram-v2
[*] --> VALIDATE_INPUT
VALIDATE_INPUT --> [*]: invalid
VALIDATE_INPUT --> READ_EXISTING
READ_EXISTING --> READ_REFERENCE: snapshot saved (entry present)
READ_EXISTING --> RESOLVE_SOURCES: entry absent
RESOLVE_SOURCES --> READ_REFERENCE
RESOLVE_SOURCES --> [*]: source / family resolution failed → BLOCKED
READ_REFERENCE --> DRAFT_ENTRY
DRAFT_ENTRY --> VALIDATE
VALIDATE --> DRAFT_ENTRY: L0 fail
VALIDATE --> RUN_AUDIT: L0 pass
RUN_AUDIT --> CREATE_ISSUE
CREATE_ISSUE --> CREATE_PR
CREATE_PR --> [*]
```
## Steps
### 1. VALIDATE_INPUT
Reject `ref_url` not matching the regex. Reject `op_name` not matching `^[A-Z][A-Za-z0-9]+(Fwd|Bwd)Op$`.
### 2. READ_EXISTING
Look up `op_name` in `tileops/manifest/`.
- **Present** → snapshot the human-curated fields per the Contract table. Source paths come from the existing `source.*`. Proceed to READ_REFERENCE.
- **Absent** → greenfield. Proceed to RESOLVE_SOURCES.
### 3. RESOLVE_SOURCES (greenfield only)
Lookup is **class-based**, not filename-based — many TileOPs ops share a file (e.g., `SumFwdOp` and `MeanFwdOp` both in `tileops/ops/reduction/reduce.py`).
1. **`source.op`**: scan `tileops/ops/**/*.py` for `class <op_name>(...)` (AST or `grep -rlE "^class <op_name>\(" tileops/ops/`).
- Exactly one match → that file path.
- Zero matches → true greenfield. Default to `tileops/ops/<snake_name>.py` (use a family subdirectory if a sibling-family entry suggests one). `<snake_name>` = `op_name` minus trailing `FwdOp` / `BwdOp`, snake_cased (`RMSNormFwdOp` → `rms_norm`). File may not exist yet; caller scaffolds afterward.
- Multiple → BLOCKED disambiguation.
1. **`source.kernel`** (required by L0; `fix-manifest` cannot fill it later):
- If `source.op` was found by class lookup: read its imports for a `Kernel` subclass; apply class-lookup under `tileops/kernels/**/*.py`. One match → that file. Multiple → BLOCKED disambiguation.
- No kernel import (kernel-less op) → `source.kernel = source.op`.
- Otherwise → BLOCKED `evidence_needed: source.kernel for <op_name>`.
1. `source.test = tests/ops/test_<snake_name>.py`; `source.bench = benchmarks/ops/bench_<snake_name>.py`. Missing files: record absent.
1. **`family`** (required by L0; cannot be empty):
- Copy from a sibling manifest entry whose `source.op` parent-dir or basename overlaps.
- No matching sibling → BLOCKED `evidence_needed: family for <op_name>`. Never invent.
### 4. READ_REFERENCE
`WebFetch(ref_url)`. Sole source of truth.
| Reference param kind | Goes to |
| -------------------- | -------------------------------------- |
| Tensor | `signature.inputs` (positional order) |
| non-Tensor | `signature.params` (`type`, `default`) |
| return | `signature.outputs` |
Names match the reference verbatim. Include every reference param even if the kernel ignores it. Exclude `float64` and `complex32/64/128` (TileOPs is GPU-only).
For references with `Optional[Tensor]` inputs, the caller has decided which slice corresponds to `op_name` (primary = required only; variant = primary + chosen optional). The skill emits inputs accordingly.
### 5. DRAFT_ENTRY
Snapshot present (re-align) → preserve human-curated fields verbatim. Snapshot absent (greenfield) → use Contract defaults. Auto-derivable fields:
- `signature.inputs`: ordered dict in the reference's positional order. Per input: `dtype` = supported set joined with `|` (reference dtypes minus `float64` and complex types); `shape` only if fixed rank; `layout` only if non-default; `constraints` if applicable.
- `signature.outputs`: same shape as inputs. Use `same_as(<ref>)` where applicable.
- `signature.params`: ordered dict, each `{type, default}`.
- `signature.shape_rules`: Python expressions for derived dims and inter-tensor constraints.
- `signature.dtype_combos`: only if supported set ⊂ Cartesian product; else omit.
- `roofline`: required by L0. Well-known op (conv / pool / matmul / norm / reduction): standard formula. Fixed-rank: shape names auto-bind, use `elem_bytes`. Arbitrary-rank: `vars` mapping. Not derivable → BLOCKED `evidence_needed: roofline.flops|bytes for <op_name>`.
### 6. VALIDATE
```bash
python scripts/validate_manifest.py --check-op <op_name>
```
L0 must pass. On fail: edit entry, rerun. L1–L4 failures go to the follow-up issue, not blocking.
### 7. RUN_AUDIT
Invoke `audit-family` for the op's family → `.foundry/migrations/<family>.json`.
### 8. CREATE_ISSUE
Invoke `foundry:creating-issue`. Per `semantic_gap` op the body MUST contain: kernel feasibility (cite kernel code; classify each missing param `trivial` / `kernel-change` / `blocked`); class-structure impact; effort per gap item; family dependencies. MUST also list outstanding human decisions (`workloads`, `roofline`) and resolution path. MUST NOT duplicate validator-reported facts. Record the issue URL.
### 9. CREATE_PR
Invoke `foundry:creating-pull-request` (draft):
| Snapshot at READ_EXISTING | Title | Branch |
| ------------------------- | ----------------------------------------------------------- | ---------------------------------------- |
| absent | `[Maintain][Manifest] Add <op_name>` | `maintain/manifest/<op-slug>` |
| present | `[Refactor][Manifest] Re-align <op_name> spec to <ref_api>` | `refactor/manifest/regenerate-<op-slug>` |
Body: which fields were rewritten vs. preserved, validator results, `Related: #<issue from step 8>`. Title and branch must match `.claude/conventions/types.sh`.

name: align-family
description: Drive the full migration for an op family — audit, delegate per-op alignment to align-op, run cross-op cleanup. Two terminal outcomes: SUCCESS opens a PR; CLEANUP_REGRESSION exits blocked without a PR when post-cleanup tests fail.
---
## Arguments
Family name from `tileops/manifest/` (e.g., `reduction`, `norm`, `attention`).
## Contract
- **Input**: `family` name
- **Output** (two terminal outcomes):
- **SUCCESS**: PR URL + final report — all ops processed via `align-op` (promoted or blocked), cleanup succeeds, PR opens.
- **BLOCKED**: blocked report (no PR) — reached when CLEANUP detects a regression in a promoted op's tests after dual-path removal; see `CLEANUP_REGRESSION` terminal in the state diagram. Distinct from the non-terminal per-op `REPORT_BLOCKED` state.
- **Termination**: all ops processed (promoted or blocked via `align-op`) and either (a) CLEANUP + CREATE_PR succeed, or (b) a promoted op's tests fail after CLEANUP's dual-path removal, causing the run to exit via `CLEANUP_REGRESSION` with the regression recorded. (`REPORT_BLOCKED` is the non-terminal per-op blocked state and never terminates the run.)
## Trust Model
- `align-family` delegates every per-op stage to `align-op`, invoked as a **separate sub-agent** per op. The family orchestrator never runs any atomic per-op skill directly — those live inside `align-op`'s contract.
- `align-family` does **not** write `tileops/manifest/`. After the refactor, `align-op` is the sole manifest writer (at its own FLIP_STATUS step); `align-family` observes status transitions via `align-op`'s SUCCESS return. No `align-family` stage edits, modifies, or flips the manifest.
- Directly-invoked sub-skills of `align-family` are exactly two: `audit-family` (in AUDIT) and `align-op` (per op).
| Stage | Sub-skill |
| -------- | -------------- |
| AUDIT | `audit-family` |
| ALIGN_OP | `align-op` |
## Workflow
```mermaid
stateDiagram-v2
[*] --> AUDIT
AUDIT --> GROUP_BY_BASE: gap report generated
GROUP_BY_BASE --> ROUTE: ops grouped by base class
ROUTE --> ALIGN_OP: ready (mode=minor) or semantic_gap (mode=redesign)
ROUTE --> REPORT_BLOCKED: classification=blocked (audit-family)
ALIGN_OP --> CLEANUP_GATE: align-op SUCCESS
ALIGN_OP --> REPORT_BLOCKED: align-op BLOCKED
REPORT_BLOCKED --> CLEANUP_GATE: record blocked reason
CLEANUP_GATE --> ROUTE: group incomplete, next op
CLEANUP_GATE --> CLEANUP: all siblings promoted or blocked
CLEANUP --> ROUTE: legacy path removed, next group
ROUTE --> CREATE_PR: all ops processed
CLEANUP --> CLEANUP_REGRESSION: promoted op test fails after cleanup
CLEANUP_REGRESSION --> [*]: terminal blocked, no PR
CREATE_PR --> [*]
```
## Orchestrator Discipline
### Clean worktree between sub-agents
After each sub-agent returns and before dispatching the next, verify:
```bash
test -z "$(git status --porcelain)"
```
This catches tracked changes, staged changes, AND untracked files. If not clean: the sub-agent's commit failed (pre-commit hook, staging issue) or left new files uncommitted. Orchestrator commits on behalf, then proceeds. Every agent must start with a clean worktree.
### Dual-path is acceptable during migration
When `align-op` rewrites a base class during its per-op pipeline, it may create a dual-path `__init__` (legacy + spec) to keep unmigrated sibling tests passing. This is correct temporary debt — the cleanup gate removes it.
**Dual-path definition**: a class `__init__` with runtime branching to support two incompatible construction interfaces, and `forward` dispatching to two execution paths. Not polymorphism — same semantics, temporary interface coexistence.
## Steps
### 1. AUDIT
```
/audit-family <family>
```
Gap report written to `.foundry/migrations/<family>.json`.
### 2. GROUP_BY_BASE
Group ops by `base_class` from the gap report. Each group is a set of sibling ops sharing a base class. Process groups in order; within each group, process ops in order (first op likely fixes the base class, subsequent ops validate).
`base_class` is a required field in the gap report. audit-family must populate it for every op entry. If an op inherits `Op` directly (no intermediate base class), its `base_class` is `"Op"` — these ops form a single group but are independent (no shared base class to rewrite, so cleanup gate is a no-op for this group).
Track group completion: a group is complete when all its ops are `promoted` or `blocked`.
### 3. ROUTE
Read the gap report from AUDIT. For each op in the current group, route by `classification` (the field `audit-family` populates):
| Gap-report `classification` | Action | Why |
| --------------------------- | ------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `ready` | → ALIGN_OP with `--mode=minor` | Existing code already conforms; align-op's minor path runs the spec tests (DONE_SKIP since they pass), then the shared downstream + flip. |
| `semantic_gap` | → ALIGN_OP with `--mode=redesign` | Family-scoped historical migration treats every `semantic_gap` op as a structural redesign by default — legacy code is being replaced wholesale. For per-op `semantic_gap` cases that are actually minor manifest deltas, use single-op `align-op <op> --mode=minor` directly instead of `align-family`. A future `recommended_mode` gap-report field could refine the routing automatically. |
| `blocked` | → REPORT_BLOCKED with audit's `reason`. Skip align-op. | Audit determined the op cannot be migrated autonomously (no `pytorch_equivalent`, kernel-layer change required, etc.). No per-op work to do. |
The mapping is deterministic — `align-family` MUST pass `--mode=` explicitly so `align-op` never falls into its interactive prompt branch in a batch family migration.
### 4. ALIGN_OP (per op)
For each op routed here, invoke `align-op` as a **separate sub-agent** with the mode determined in Step 3:
```
align-op <op_name> --mode=<minor|redesign>
```
`align-op` owns the entire per-op pipeline internally — its internal stages (classify, dispatch on case, test / implement / bench, revalidate, flip status, cleanup, report) are `align-op`'s contract, not `align-family`'s. See [`align-op/SKILL.md`](../align-op/SKILL.md) for the authoritative stage list and the conditional-IMPLEMENT rule. `align-family` does not manage or observe `align-op`'s internal stages; the only interface between them is `align-op`'s SUCCESS / BLOCKED return.
Per-op outcome:
- `align-op` returns SUCCESS → op is `promoted` (manifest status already flipped by `align-op`'s FLIP_STATUS). Record the returned report. Proceed to CLEANUP_GATE.
- `align-op` returns BLOCKED → op is `blocked`. Capture `align-op`'s BLOCKED reason verbatim as the per-op result. Proceed to CLEANUP_GATE.
`align-family` MUST NOT re-flip manifest status or re-run per-op validation on its own; `align-op`'s SUCCESS return is the single source of truth that the manifest was flipped.
The flip performed by `align-op` MUST stay within the [Status flip carve-out](../../rules/manifest-trust-model.md#status-flip-carve-out); `align-family` MUST NOT batch contractual-field edits across ops in the same PR.
### 5. CLEANUP_GATE
After each per-op outcome — whether `align-op` returned SUCCESS / BLOCKED or ROUTE recorded an audit-classified `blocked` op directly to `REPORT_BLOCKED` — check group completion:
- All siblings in the current base-class group are `promoted` or `blocked`? → trigger CLEANUP
- Otherwise → continue to next op (ROUTE → ALIGN_OP)
### 6. CLEANUP
Remove dual-path legacy code from the base class. This step fires once per base-class group, after all siblings have gone through `align-op` (SUCCESS or BLOCKED).
Actions:
1. Remove legacy `__init__` branch (`if M is not None and N is not None` path)
1. Remove `_legacy` flag and `_forward_legacy` method
1. Remove `M`, `N` keyword-only parameters from `__init__`
1. Run tests and `--check-op` for **promoted ops only** (blocked ops' tests may legitimately fail)
1. Commit cleanup changes
If any promoted op's test fails after cleanup → transition to `CLEANUP_REGRESSION` (terminal): record the regression, skip `CREATE_PR`, exit with `blocked` status. Do not proceed with a broken state.
**Two distinct blocked states**, split so the diagram has one meaning per state:
- **`REPORT_BLOCKED`** — per-op `align-op` returned BLOCKED. Records the reason, returns to `CLEANUP_GATE`, continues with sibling ops. Non-terminal.
- **`CLEANUP_REGRESSION`** — a promoted op's tests fail after CLEANUP's dual-path removal. Terminal: the family migration exits without opening a PR. The blocked report becomes the run's final artefact.
**Timeout policy for blocked ops**: if a group has blocked ops that prevent the cleanup gate from firing for an extended period, the orchestrator may force cleanup — remove legacy path and mark blocked ops' tests as `xfail`. This is a human decision, not automatic.
### 7. CREATE_PR
After all ops processed:
- Collect all per-op reports returned by `align-op`
- Create PR with:
- Migration summary (promoted / blocked counts)
- Per-op change table (derived from `align-op` reports)
- Observations surfaced by `align-op` (e.g., `needs_kernel_work`, `needs_human_decision`) for human doc review
- Blocked ops with `align-op`'s BLOCKED reasons

name: align-op
description: Per-op orchestrator that brings a single op into alignment with its manifest entry. Classifies the op into one of three cases (green field / interface redesign / minor delta), dispatches to the right path (scaffold-op for new, archive+rescaffold+port for redesign, implement-op for minor), then runs the shared downstream (test → bench → validate → flip status → report). Complements the family-scoped `align-family`; per-op entry when you know the op you want to touch.
---
## Arguments
- `op_name` (positional) — manifest key, e.g. `CumsumFwdOp`.
- `--mode=green|redesign|minor` (optional) — override the automatic classification. When omitted, `CLASSIFY` decides (auto if unambiguous, otherwise prompt).
- `--classify-only` (optional) — stop after `CLASSIFY`; write `mode.json` and return without executing any case path. Use to ask "which case is this op in?" without side effects.
## Contract
- **Input**: `op_name` must be present in [`tileops/manifest/`](../../../tileops/manifest/) with `status: spec-only` and a non-empty `source.kernel_map` (same preconditions as scaffold-op; see [PRE_CHECK](#pre_check)).
- **Path and data bindings used throughout this skill** (resolved by the orchestrator once at `PRE_CHECK` when the manifest entry is first loaded, then passed into every sub-skill invocation):
- `<source_op>` — manifest `source.op` path (e.g., `tileops/ops/reduction/cumsum.py`).
- `<source_test>` — manifest `source.test` path (e.g., `tests/ops/test_cumulative.py`).
- `<source_bench>` — manifest `source.bench` path.
- `<source_kernel>` — manifest `source.kernel` path (the primary kernel implementation file).
- `<manifest_signature>` — the `signature` sub-tree from the op's manifest entry, passed verbatim to test-op / implement-op.
- `<pytorch_equivalent>` — manifest `ref_api` value (e.g., `"torch.cumsum"`) or `null` if the op has no PyTorch reference. Required by test-op.
- **Output** (SUCCESS path): op file at `source.op` aligned with the manifest; test file `source.test` aligned; `__init__.py` registrations consistent; `status` flipped `spec-only → implemented` (single commit). Side-artefacts in `.foundry/plan/<op_name>/`: `mode.json` (classification), `plan.json` (scaffold-op's §1/§2/§3 when that skill ran), `kernel-check.json` (redesign case only), `pre-rewrite/source.py` (redesign case, removed at CLEANUP on SUCCESS).
- **Termination (success)**: `python scripts/validate_manifest.py --check-op <op_name>` reports no errors + `python -m pytest <source_test> -v` passes + benchmark produces numbers + manifest status flipped.
- **Termination (blocked)**: any sub-skill (scaffold-op / test-op / implement-op / bench-op) returns blocked; or scaffold-op §1 drift; or REVALIDATE fails. Kernel-layer mismatches surfaced by `KERNEL_CHECK` are **informational only** and never cause BLOCKED by themselves — BLOCKED is reached only if a kernel drift propagates into a downstream sub-skill failure (e.g., bench-op runtime error, REVALIDATE regression). Archives are kept for post-mortem.
- **Constraints**:
- Only align-op (and only at FLIP_STATUS) may modify `tileops/manifest/`. Sub-skills never touch the manifest.
- MUST NOT modify kernel code. Kernel-layer work, if needed, is surfaced via `kernel-check.json` as a separate follow-up.
- MUST NOT expand to multi-op scope; that is `align-family`'s role.
## Trust model
- `CLASSIFY`, `DISPATCH`, `FLIP_STATUS`, `CLEANUP`, `REPORT` are orchestrator stages (align-op itself). Every other stage delegates to an atomic skill as a **separate sub-agent invocation**:
| Stage | Sub-skill |
| ------------- | ------------------------------------------------------------ |
| GREEN path | `scaffold-op` |
| REDESIGN path | `scaffold-op` (after ARCHIVE + CLEAR) |
| MINOR path | `implement-op` |
| TEST | `test-op` |
| IMPLEMENT | `implement-op` (green / redesign only; minor already did it) |
| BENCH | `bench-op` |
Separate invocations preserve the per-skill contracts (e.g., scaffold-op's §1 fact-freeze; implement-op's no-test-modification rule).
- After each sub-skill returns, align-op verifies `git status --porcelain` is empty before dispatching the next. If a sub-skill left an uncommitted change, align-op commits on its behalf with `Sub-skill [name]: [summary]` before proceeding.

```
## Steps
### <a id="pre_check"></a>1. PRE_CHECK
Preconditions identical to `scaffold-op`'s — orchestrator enforces them up front so sub-skills never see ill-formed input:
- `op_name` in `tileops/manifest/` → proceed; otherwise BLOCKED ("op not in manifest").
- `status: spec-only` → proceed; `implemented` → BLOCKED ("already aligned; flip status to spec-only in a manifest PR first if you intend to re-align"); missing/other → BLOCKED.
- `source.kernel_map` declared and non-empty → proceed; missing → BLOCKED with the same guidance scaffold-op uses (add in a prerequisite manifest PR).
- Every value in `source.kernel_map` resolves to an importable symbol → proceed; otherwise BLOCKED ("kernel class not found at expected path" — kernel must exist for op layer to align, regardless of case).
### 2. CLASSIFY
Decide which case applies. Machine-decidable input: does `source.op` exist?
| Input | Auto case | User prompt? |
| -------------------------- | --------- | ----------------------------------------------------------- |
| `source.op` does not exist | `green` | no |
| `source.op` exists | (unknown) | yes — "redesign (rewrite + port) or minor (in-place edit)?" |
`--mode=<case>` overrides prompting only when consistent with file presence. The orchestrator validates this during CLASSIFY and BLOCKs immediately on invalid combinations so sub-skills never see contradictory input:
- `source.op` **missing** → only `green` is valid. `--mode=minor` → BLOCKED ("`source.op` is missing; cannot edit a non-existent op file; use `--mode=green` or omit `--mode`"). `--mode=redesign` → BLOCKED ("`source.op` is missing; no archive source to rewrite; use `--mode=green` or omit `--mode`").
- `source.op` **exists** → `--mode=green` → BLOCKED ("`source.op` already exists; green-field scaffold would silently overwrite; use `--mode=redesign` for rewrite+port or `--mode=minor` for in-place edit").
**First-op bias.** If no op in the same `family` has `status: implemented` and follows the canonical pattern (`docs/design/ops-design.md` § Step 3), set `auto-case = redesign` (skip the prompt). mode.json: `decided_by: "auto"`, `reason: "no canonical-pattern precedent in family <name>"`. User may override with `--mode=minor`.
Write `.foundry/plan/<op_name>/mode.json`:
```json
{
"op_name": "CumsumFwdOp",
"case": "redesign",
"file_present": true,
"kernel_class_importable": true,
"decided_by": "user_prompt",
"reason": "User declared: manifest _static_axes shape rewritten; structural redesign.",
"classified_at": "YYYY-MM-DDTHH:MM:SSZ"
}
```
`decided_by` is one of `auto` / `user_prompt` / `flag_override`. `reason` is free-form text.
If `--classify-only` was passed, terminate here and print the mode.json content. No other side effects.
### 3. DISPATCH — case-specific main stage
Each path produces the aligned op file under `source.op` plus whatever artefacts the sub-skill creates under `.foundry/plan/<op_name>/`.
#### 3a. GREEN path (`case = green`)
```
scaffold-op <op_name>
```
Sub-skill does PRE_CHECK → DRY_RUN (plan.json) → EMIT → REGISTER → VALIDATE → REPORT. align-op waits for SUCCESS or BLOCKED; on BLOCKED, surface the row and terminate.
#### 3b. REDESIGN path (`case = redesign`)
Sequence:
1. **ARCHIVE** — `mkdir -p .foundry/plan/<op_name>/pre-rewrite/`, copy `source.op` there as `source.py` (rename: strip family path, keep basename). The archive is the source of truth for manual porting. It persists until CLEANUP.
1. **CLEAR** — remove `source.op` from the tree; remove the op's `from .<module> import <ClassName>` line and its `__all__` entry from the package `__init__.py`. Commit as `[Chore] align-op: archive <op_name> before rescaffold`.
1. **SCAFFOLD** — `scaffold-op <op_name>`. Target now absent, PRE_CHECK passes, emits the 17 mechanical slots.
1. **PORT** — read `pre-rewrite/source.py` and port op-specific content that the scaffold cannot produce:
- Optional hooks (`_pad_value`, `_validate_dim`, `_pre_kernel`, `_post_kernel`, `_cache_key` override).
- Family-specific protocol variables (`_op_kind`, `_kernel_key`, `_kernel_cls`, etc.) if the op was a T1 thin wrapper.
- Any `forward` body specifics beyond the universal pattern (kernel-specific reshape/movedim choreography).
- Any class-level non-slot attributes the old file had that still make sense under the new spec.
Commit as `[Feat] align-op: port business logic for <op_name> from pre-rewrite`. If the agent is uncertain whether a specific override should be ported, record an `open_questions` item in plan.json §3 (`needs_human_decision`) and port conservatively.
1. **KERNEL_CHECK** — see §5 below.
#### 3c. MINOR path (`case = minor`)
```
implement-op(
op_name=<op_name>,
manifest_signature=<manifest_signature>,
source_op=<source_op>,
source_test=<source_test>
)
```
Sub-skill does ANALYZE → DIAGNOSE → IMPLEMENT → VALIDATE → MARK_DONE → COMMIT. align-op waits for SUCCESS or BLOCKED.
### 4. Skipped anchor (reserved)
### <a id="kernel_check"></a>5. KERNEL_CHECK (redesign path only)
Determine whether the kernel layer also needs work. align-op does **not** modify kernel code; it surfaces the question.
For each Kernel class referenced in `source.kernel_map`:
1. Inspect the kernel's `__init__` / `forward` / `_build_program` signatures (wherever applicable) in its source file.
1. Compare against the new op's kernel-build call emitted by scaffold-op (`self.kernel_map[<key>](<args>)`). Specifically check:
- Argument names and positional order.
- Argument types.
- Any layout / dtype expectations the kernel documents.
1. Classify per kernel:
- `aligned` — new op's kernel invocation matches the kernel's ctor; no kernel work.
- `signature_drift` — arg names or order differ; kernel ctor must be adjusted.
- `semantic_drift` — the kernel expects a different data layout / dtype than the new op provides (e.g. op now passes `(M, N)` where kernel expects `(N, M)`).
- `unknown` — cannot determine from static inspection.
Write `.foundry/plan/<op_name>/kernel-check.json`:
```json
{
"op_name": "CumsumFwdOp",
"checked_at": "YYYY-MM-DDTHH:MM:SSZ",
"kernels": [
{
"dispatch_key": "cumulative_fwd",
"kernel_class": "CumulativeKernel",
"kernel_source": "tileops/kernels/reduction/cumulative.py",
"classification": "aligned",
"op_call": "self.kernel_map['cumulative_fwd'](M, N, 'sum', self.dtype, tune=self.tune)",
"kernel_ctor": "__init__(self, M, N, op_kind, dtype, *, tune=False)",
"notes": "Positional and named args match; no kernel work required."
}
]
}
```
Non-`aligned` entries surface in REPORT as `needs_kernel_work` follow-ups. align-op itself continues to TEST — the downstream path may still pass if the kernel drift only affects performance (not correctness), or fail fast if the kernel mismatch causes runtime errors, which REVALIDATE will catch.
### 6. TEST
```
test-op(
op_name=<op_name>,
manifest_signature=<manifest_signature>,
pytorch_equivalent=<pytorch_equivalent>,
source_test=<source_test>
)
```
Sub-skill writes tests against the new spec. Termination:
- **tests fail on current code** (expected TDD seed) → proceed to IMPLEMENT.
- **DONE_SKIP** (tests already pass, e.g. a sibling migration fixed the base class, or minor-path `implement-op` already closed the gap in Step 3c) → skip IMPLEMENT, proceed to BENCH.
### 7. IMPLEMENT
```
implement-op(
op_name=<op_name>,
manifest_signature=<manifest_signature>,
source_op=<source_op>,
source_test=<source_test>
)
```
Closes the gap between the emitted op file and the tests from Step 6. Applies to:
- **Green path**: `scaffold-op` produced the 17 mechanical slots, but not optional hooks or family protocol vars; `implement-op` fills any that are required for the tests to pass.
- **Redesign path**: the `PORT` sub-step in Step 3b did a first pass; `implement-op` closes residual gaps surfaced by the tests.
- **Minor path**: **skipped** — `implement-op` already ran as the minor-case main stage in Step 3c. If TEST didn't DONE_SKIP here, that signals spec-drift beyond the minor-case scope and becomes BLOCKED.
BLOCKED if the gap requires kernel-layer changes (align-op is op-layer only; kernel work surfaces via `kernel-check.json` from KERNEL_CHECK or as a `blocked` return from `implement-op`).
### 8. BENCH
```
bench-op(
op_name=<op_name>,
source_bench=<source_bench>,
source_op=<source_op>
)
```
Produces numbers. Sub-skill unchanged. If BLOCKED and reason is not kernel-related, propagate blocked.
### 9. REVALIDATE
```bash
python scripts/validate_manifest.py --check-op <op_name>
python -m pytest <source_test> -v
```
Both must pass. Regression after benchmark changes → BLOCKED.
### 10. FLIP_STATUS
Orchestrator (not a sub-skill) edits the manifest:
- `ops.<op_name>.status: spec-only` → `status: implemented`
- Commit as `[Refactor][Manifest] promote <op_name> to implemented`.
This is the only manifest write in the entire workflow, and it MUST stay within the [Status flip carve-out](../../rules/manifest-trust-model.md#status-flip-carve-out); any contractual-field change requires a separate manifest-only PR.
### 11. CLEANUP
On SUCCESS path:
- Delete `.foundry/plan/<op_name>/pre-rewrite/` (redesign case only; archive purpose is served).
- Keep `mode.json`, `plan.json`, `kernel-check.json` as audit trail — they are under `.foundry/plan/` which is gitignored but persists in the local worktree.
On BLOCKED path: keep all artefacts for post-mortem.
### 12. REPORT
Single-page summary printed to stdout. Always includes:
```
Status: SUCCESS | BLOCKED
Op: <op_name>
Case: green | redesign | minor
Mode decided by: auto | user_prompt | flag_override
File: <source.op> (<lines>)
Sub-skills run:
- scaffold-op: <SUCCESS|BLOCKED|skipped>
- implement-op: <...>
- test-op: <...>
- bench-op: <...>
Plan artefacts (.foundry/plan/<op_name>/):
- mode.json
- plan.json (if scaffold-op ran)
- kernel-check.json (if redesign path)
- pre-rewrite/ (redesign path, cleaned on SUCCESS)
Status flipped: spec-only → implemented (commit <sha>)
Follow-ups:
- <needs_kernel_work for kernel X> (from kernel-check.json non-aligned entries)
- <needs_doc_fix for slot S21> (from plan.json §3)
- <needs_human_decision about port of _pad_value> (from port observations)
```
On BLOCKED, replace "Status flipped" line with the blocking error and list remaining follow-ups.
## Interaction with `align-family`
`align-family` is the family-scoped orchestrator and delegates every per-op stage to `align-op`. Its workflow is `AUDIT → GROUP_BY_BASE → ROUTE → (per op: ALIGN_OP) → CLEANUP_GATE → CLEANUP → CREATE_PR`; the family orchestrator never invokes the atomic per-op skills (`scaffold-op` / `test-op` / `implement-op` / `bench-op`) directly — every per-op stage runs inside `align-op`'s contract.
- Use `align-op <op>` for per-op work (green field, redesign, or minor delta).
- Use `align-family <family>` for family-scoped historical migration of many ops at once.
They do not conflict. `align-op` never manages cross-op cleanup gates; that remains `align-family`'s. `align-op`'s `FLIP_STATUS` is the sole manifest-write site, observed by `align-family` via `align-op`'s SUCCESS return.
## Non-goals
- **Kernel scaffolding / kernel-layer edits.** align-op surfaces kernel work as a follow-up via `kernel-check.json`; a separate (future) `kernel-scaffold` / `kernel-align` skill will own that layer.
- **Family-level cleanup.** Cross-op dual-path removal lives in `align-family` and is not a concern of per-op alignment.
- **General auto-detection of "redesign vs minor."** The distinction is a design judgement; align-op prompts or accepts `--mode`. The one exception is the **first-op bias** in CLASSIFY (no canonical-pattern precedent in the family → auto `redesign`). Beyond that one case, no auto-detection.
- **Manifest changes (other than FLIP_STATUS).** Per the trust model, manifest changes live in separate manifest PRs.

description: Compare each op's code signature against its manifest spec, classify gaps, produce a structured report.
---
## Arguments
Family name from `tileops/manifest/` (e.g., `reduction`, `norm`, `attention`).
## Contract
- **Input**: `family` name
- **Output**: `.foundry/migrations/<family>.json`
- **Termination**: all ops classified. `ready` ops verified via `--check-op`.
## Workflow
```mermaid
stateDiagram-v2
[*] --> LOAD_MANIFEST
LOAD_MANIFEST --> FILTER: manifest loaded
FILTER --> SELECT_OP: spec-only ops filtered by family
SELECT_OP --> READ_CODE: op selected
READ_CODE --> COMPARE_SIGNATURE: code inspected
COMPARE_SIGNATURE --> CHECK_OP_VALIDATE: no signature difference
COMPARE_SIGNATURE --> CHECK_PYTORCH_REF: difference found
CHECK_OP_VALIDATE --> mark_ready: --check-op passes all levels
CHECK_OP_VALIDATE --> CHECK_PYTORCH_REF: --check-op fails (deeper gap)

mark_ready --> SELECT_OP: next op

mark_blocked --> SELECT_OP: next op
SELECT_OP --> WRITE_REPORT: all ops classified
WRITE_REPORT --> [*]
```
Key gate: `pytorch_equivalent` determines autonomous vs human-required migration. `--check-op` confirms `ready` classification.
## Classification
| Classification | Condition | Downstream |
| -------------- | ------------------------------------------------------------------ | ----------------------------------- |
| `ready` | `--check-op` passes, no signature difference | Orchestrator flips status directly |
| `semantic_gap` | Manifest-code difference + `pytorch_equivalent` exists | test-op → implement-op |
| `blocked` | Difference but no PyTorch reference; or kernel-level change needed | Terminate. `reason` field explains. |
## Gap Report Format
Location: `.foundry/migrations/<family>.json`
Top-level:
```json
{
"family": "reduction",
"audited_at": "2026-04-03T...",
"total": 21,
"summary": {"ready": 0, "semantic_gap": 21, "blocked": 0},
"ops": { "<op_name>": { ... } }
}
```
Per-op entry. **Example — field set is not exhaustive. Add fields that aid the next step, omit those that don't.**
```json
{
"status": "spec-only",
"source_op": "tileops/ops/reduction/softmax.py",
"base_class": "_SoftmaxBaseOp",
"classification": "semantic_gap",
"missing_params": ["dim"],
"manifest_signature": {
"inputs": {"x": {"dtype": "float16 | bfloat16"}},
"outputs": {"y": {"dtype": "same_as(x)"}},
"params": {"dim": {"type": "int", "default": -1}},
"shape_rules": ["y.shape == x.shape"]
},
"manifest_param_order": ["x", "dim"],
"pytorch_equivalent": "torch.nn.functional.softmax",
"notes": "dim hardcoded to -1"
}
```
Required fields: `classification`, `source_op`, `base_class`, `manifest_signature`. `base_class` is the immediate parent class name (e.g., `_SoftmaxBaseOp`); if the op inherits `Op` directly, use `"Op"`. The orchestrator uses `base_class` for GROUP_BY_BASE grouping. Gap report is a starting point — agent reads live code and manifest during downstream skills.
`pytorch_equivalent`: corresponding PyTorch function, or `null`. Not every op has one.
## Steps
1. Load the merged manifest via `from tileops.manifest import load_manifest`, or read `tileops/manifest/<family>.yaml` directly when scoping to one family.
1. Filter ops where `family == <arg>` and `status == spec-only`
1. For each op:
a. Read source file (`source_op`), find Op class, extract `__init__` and `forward` explicit named params
b. Compare against `manifest_signature` (inputs, params)
c. If no difference → run `python scripts/validate_manifest.py --check-op <name>` to confirm → `ready` or deeper gap
d. If difference → determine `pytorch_equivalent`:
- Strip `_fwd` suffix, match against `torch.nn.functional`, `torch`, `torch.special`, `torch.linalg` → `semantic_gap`
- `_bwd` ops → always `blocked` (PyTorch backward is autograd-internal, no public reference function for autonomous testing)
- No match → `blocked`
1. Write gap report to `.foundry/migrations/<family>.json`
1. Print summary table

name: bench-op
description: Fix benchmark file to work with the new Op interface. Run benchmark, fix errors, repeat until it produces numbers.
---
## Arguments
`op_name`, `source_bench`, `source_op` — passed by align-family orchestrator.
## Contract
- **Input**: `op_name`, `source_bench`, `source_op`
- **Output**: updated benchmark file + commit
- **Termination (success)**: benchmark runs to completion, produces numeric output (latency/TFLOPS/bandwidth)
- **Termination (blocked)**: failure is not interface-related (e.g., kernel bug). Return `blocked` with reason.
- **Constraint**: must NOT modify Op implementation or tests. Benchmark-only changes.
- **Environment**: local GPU required.
## Workflow
```mermaid
stateDiagram-v2
[*] --> RUN_BENCH
RUN_BENCH --> DONE: benchmark produces numbers
RUN_BENCH --> FIX_ERROR: runtime error
FIX_ERROR --> RUN_BENCH: benchmark code fixed
FIX_ERROR --> BLOCKED: error is not interface-related
BLOCKED --> [*]: return blocked to orchestrator
DONE --> COMMIT
COMMIT --> [*]
```
## Steps
### 1. RUN_BENCH
Execute the benchmark file:
```bash
python -m pytest <source_bench> -v
```
If it runs and produces numbers → DONE.
### 2. FIX_ERROR
Read the traceback. The error is the signal — typically the benchmark constructs the Op with the old interface (e.g., `Op(M, N, dtype)` instead of `Op(dim, dtype)`).
Fix the benchmark construction code to use the new Op interface. This is interactive — fix what breaks, don't predict errors in advance.
If the error is NOT about interface mismatch (e.g., kernel crash, CUDA error) → BLOCKED.
### 3. COMMIT
Commit benchmark changes only. Follow `docs/design/testing.md` benchmark requirements.

name: fix-manifest
description: Patch one missing structural field (kernel_map, static_dims) on an existing tileops/manifest/ entry. Auto-detects the field via the validator or takes `--field=<name>`. Reference-derivable fields (signature.*, shape_rules, dtype_combos, roofline) belong to add-manifest, not here.
---
## Arguments
| Argument | Required | Description |
| ---------------- | -------- | -------------------------------------------------------------------------------------------------- |
| `op_name` | Yes | One manifest key, or comma-separated list (e.g., `RMSNormFwdOp` or `SumFwdOp,MeanFwdOp,VarFwdOp`). |
| `--field=<name>` | No | One of `kernel_map`, `static_dims`. Omit to auto-detect. |
| `--dry-run` | No | Print diff and exit; no write, no PR. |
Multi-op: same `--field` applied to every op in the list. Multi-field is not supported — run again.
## Contract
- **MAY write** in `tileops/manifest/<family>.yaml` (the family file owning the entry): `source.kernel_map`, `signature.static_dims`. These two fields are derived from on-disk op / kernel evidence, not from the reference API. Use `ruamel.yaml` for round-trip preservation.
- **MUST NOT write** anything else. Reference-derivable fields (`signature.{inputs,outputs,params,shape_rules,dtype_combos}`, `roofline.*`) belong to `add-manifest` — re-aligning those fields requires re-fetching the reference URL, which is `add-manifest`'s job. Other fields (`status`, `family`, `ref_api`, `workloads`, `source.{kernel,op,test,bench,bench_manifest_driven}`) are human-curated and not touched by either skill.
- **MUST NOT** create new entries — use `add-manifest`.
- **MUST NOT** flip `status` (that is `align-op@FLIP_STATUS`).
- **MUST NOT** edit op / kernel / test / bench code.
- **One field per invocation.**
- **Termination**: every patched op's validator output is **monotonic** (no new error category vs. before the patch), or BLOCKED.
## Workflow
```mermaid
stateDiagram-v2
[*] --> PRE_CHECK
PRE_CHECK --> [*]: entry missing → BLOCKED
PRE_CHECK --> DIAGNOSE
DIAGNOSE --> INFER: target in allowed list
DIAGNOSE --> [*]: forbidden field → BLOCKED
DIAGNOSE --> [*]: nothing to fix
INFER --> PATCH
INFER --> [*]: cannot infer → BLOCKED
PATCH --> VALIDATE
VALIDATE --> [*]: regression → revert and BLOCK
VALIDATE --> CREATE_PR
CREATE_PR --> [*]
```
## Steps
### 1. PRE_CHECK
Resolve `op_name` in `tileops/manifest/`. Missing → BLOCKED: `op not in manifest; use add-manifest`.
### 2. DIAGNOSE
When `--field=` is provided: must be `kernel_map` or `static_dims`; else BLOCKED. Skip both checks below.
When `--field=` is omitted, run two checks in strict order:
**Check A — `kernel_map` presence.** If `source.kernel_map` is missing or empty → target = `kernel_map`, jump to INFER.
The validator only warns on missing `kernel_map` when `status == implemented`, so spec-only entries need this explicit check. Do NOT extend it to `static_dims` — `docs/design/manifest.md` (R7, R20) explicitly allows `static_dims` to be absent on fixed-rank ops; absence-only patching would manufacture changes for valid entries.
**Check B — validator output.** Run `python scripts/validate_manifest.py --check-op <op_name>`. Parse the first error:
- Field is `static_dims` → target = `static_dims`, jump to INFER.
- Field is reference-derivable (`signature.{inputs,outputs,params,shape_rules,dtype_combos}`, `roofline.*`) → BLOCKED with redirect: `"<field> belongs to add-manifest; re-align this entry with /add-manifest <op_name> <ref_url>"`.
- Other forbidden fields (`status`, `family`, etc.) → BLOCKED. Name the field, why it is out of scope, and what owns it.
- No errors and Check A also empty → no-op; print `nothing to fix` and exit 0.
Write `.foundry/plan/<op_name>/fix-diagnosis.json`: `{op_name, target_field, validator_excerpt, action}`.
### 3. INFER
Build the patch payload from on-disk evidence. **Never guess** — if inference is impossible, BLOCKED with `evidence_needed: <what>`.
**`kernel_map`** — read the op file:
- T2 (L1-direct): copy `default_kernel_map()`'s return dict verbatim.
- T1 (thin wrapper, see `docs/design/ops-design.md` § "Family-specific protocol variables"): family bases expose `default_kernel_map()` returning `{self._kernel_key: self._kernel_cls}`. Read it; substitute the subclass's `_kernel_key` / `_kernel_cls`.
- Output format per `docs/design/manifest.md` § kernel_map: `{<dispatch_key>: <BareKernelClassName>}` — bare class name, NOT fully-qualified.
**`static_dims`** — `signature.inputs` shape names that the op binds at construction time (each entry in the op's `__init__` kwarg block, excluding `dtype` / `kernel_map` / `tune` / `signature.params` entries — see `docs/design/ops-design.md` § "Step 3"). Cross-check with `roofline.vars` if present.
### 4. PATCH
First capture the validator baseline — **before any file mutation**:
```bash
python scripts/validate_manifest.py --check-op <op_name> > /tmp/fix-manifest-<op>-before.txt
```
Do NOT use `git stash` for this — unsafe on a dirty tree (pulls in unrelated user changes).
Then insert each new key as a **sibling** of existing keys in its parent block, at this exact position (verifiable from any sibling entry):
| Field | YAML path | Position |
| ------------- | ----------------------- | ----------------------------------------------------------------------------------------------------- |
| `kernel_map` | `source.kernel_map` | between `source.kernel` and `source.op` |
| `static_dims` | `signature.static_dims` | between `signature.params` and `signature.shape_rules`; if `params` absent, after `signature.outputs` |
Preserve adjacent comments. Do not reorder unrelated keys. If the existing entry deviates from the canonical layout, fall back to the order in `docs/design/manifest.md`.
### 5. VALIDATE
Capture after-baseline and diff:
```bash
python scripts/validate_manifest.py --check-op <op_name> > /tmp/fix-manifest-<op>-after.txt
diff /tmp/fix-manifest-<op>-before.txt /tmp/fix-manifest-<op>-after.txt
```
Acceptable iff after's errors are a subset of before's (monotonic). Any new error → revert that op's patch and BLOCKED.
For multi-op runs: per-op independent. One op's regression reverts only that op's patch; siblings proceed.
Spec-only entries usually carry pre-existing errors (the reason they are spec-only — typically `[signature]` mismatches). Those are out of scope here — `align-op` closes them later.
### 6. CREATE_PR
If `--dry-run`, print diff and exit 0. Otherwise invoke `foundry:creating-pull-request`:
| Element | Single-op | Multi-op |
| ------- | ------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------- |
| title | `[Maintain][Manifest] fix <field> for <op_name>` (use `[Fix][Manifest]` if validator was actively rejecting) | `[Maintain][Manifest] add <field> for <family> spec-only ops` |
| branch | `maintain/manifest/fix-<op-slug>-<field>` | `maintain/manifest/fix-<family>-<field>` |
| body | which field, evidence, validator before/after, scope guard | per-op evidence table; per-op monotonic-check result; scope guard |
## Guardrails
- One field per invocation.
- Never widen scope to a forbidden field — emit BLOCKED.
- Never invent values; payload must trace to a file or to `ref_api`.
- Never flip `status`.
- Validator output ambiguous → STOP, ask user.

name: follow-up
description: Introspect a development session and generate follow-up issues for deferred work, discovered problems, and coverage gaps. Max 3 issues per invocation.
---
## Args
| Argument | Description |
| -------------- | ----------------------------------------------------------------------------------------- |
| `<PR_NUMBER>` | Required. TileOPs PR number. |
| `--nightshift` | Skip the interactive presentation; auto-accept all candidates; inject `nightshift` label. |
## Contract
Input: PR ref + conversation (if available). Output: ≤3 follow-up issues, in-scope fixes committed, out-of-scope suggestions printed to stdout. **Never edit the PR body** — the review skill owns it.
## Modes
- **Session-rich**: introspection is primary signal; PR supplements.
- **Session-poor**: PR diff + human reviewer comments only.
## Steps
### 1. Resolve PR
```bash
NIGHTSHIFT=0
for arg in "$@"; do
case "$arg" in
--nightshift) NIGHTSHIFT=1 ;;
-*) echo "Unknown flag: $arg" >&2; exit 1 ;;
*) PR_NUMBER="${PR_NUMBER:-$arg}" ;;
esac
done
[[ -z "${PR_NUMBER:-}" ]] && { echo "Usage: /follow-up <PR_NUMBER>" >&2; exit 1; }
gh pr view "$PR_NUMBER" --json number,title,url,body
OWNER_REPO=$(gh repo view --json nameWithOwner -q '.nameWithOwner')
```
PR not found → terminate.
### 2. Collect
| Source | How |
| ----------------- | ----------------------------------------------------- |
| Diff | `gh pr diff "$PR_NUMBER"` |
| Session | Scan for deferrals, workarounds, blocked items |
| In-code markers | Grep changed files for `TODO`, `FIXME`, `HACK`, `XXX` |
| Reviewer comments | Both endpoints below, filtered to non-author non-bot |
```bash
export PR_AUTHOR=$(gh pr view "$PR_NUMBER" --json author -q '.author.login')
FILTER='[.[] | select(.user.login != env.PR_AUTHOR and .user.type != "Bot"
and (.user.login | test("copilot|gemini|github-actions"; "i") | not))]'
gh api "repos/$OWNER_REPO/pulls/$PR_NUMBER/comments" --paginate --jq "$FILTER"
gh api "repos/$OWNER_REPO/issues/$PR_NUMBER/comments" --paginate --jq "$FILTER"
```
### 3. Classify
**Issue-worthy** (→ follow-up issue):
| Category | Signal |
| ---------------- | ------------------------------------------------------ |
| Scope deferral | "not in this PR", explicit defer |
| Fragile coupling | Workarounds, monkey-patches |
| Coverage gap | Untested cases, missing edge cases, skipped benchmarks |
| Consistency gap | Doc drift; same problem in other modules |
**Suggestion** (no issue):
| Tier | Signal | Action |
| ------------ | ----------------------------------------------- | ------ |
| In-scope | Touches only this PR's files; small, mechanical | Step 7 |
| Out-of-scope | Outside diff, expands behavior, or subjective | Step 8 |
Uncertain → out-of-scope. Nothing in either bucket → step 8 (empty report). Do not manufacture follow-ups.
### 4. Merge → max 3 issues
Same module / root cause → merge. Different + independent → keep separate.
### 5. Present
`--nightshift`: skip; auto-accept; → step 6.
Default — render in dependency order, wait on `Actions:`:
```
Follow-up candidates from PR #<N>: <title>
1. [TYPE][SCOPE] <title> Category: <…> | <1–2 sentences>
2. [TYPE][SCOPE] <title> ← parallel with #1
3. [TYPE][SCOPE] <title> ← depends on #1
Execution order: {#1, #2} → #3
In-scope fixes:
- <file:line> — <nit>
Out-of-scope suggestions:
- <nit>
Actions: confirm all / drop by N / edit / move <item> to out-of-scope
```
### 6. Create — delegate to `creating-issue`
For each confirmed item: write a draft to a tmpfile, then invoke `foundry:creating-issue --from-draft <tmpfile>`. **Never `gh issue create` directly** — that bypasses the 5-section HARD GATE which `foundry:pipeline` Phase A re-validates downstream.
Draft body must conform to the canonical template at `foundry/skills/creating-issue/SKILL.md` Step 4 — `creating-issue` is the single owner; do not duplicate or paraphrase its section names here.
Frontmatter:
```yaml
---
type: <FEAT|BUG|PERF|REFACTOR|DOCS|TEST>
component: <affected module>
labels: [follow-up] # add `nightshift` only when --nightshift was passed
target_repo: <OWNER_REPO>
---
```
Labels (the `nightshift` label is human-curated — fail fast, do not auto-create):
```bash
gh label list --search follow-up --json name --jq '.[].name' | grep -qx follow-up \
|| gh label create follow-up --color c5def5 --description "Generated from dev session introspection"
if [[ "$NIGHTSHIFT" == "1" ]]; then
gh label list --search nightshift --json name --jq '.[].name' | grep -qx nightshift \
|| { echo "nightshift label missing in $OWNER_REPO" >&2; exit 1; }
fi
```
### 7. Apply in-scope fixes
For each: verify file is in `gh pr diff --name-only "$PR_NUMBER"` (else demote); Edit; run a fast check (`pre-commit run --files <paths>` or module-scoped unit tests). Commit the batch:
```
[Chore] apply in-scope follow-up suggestions from PR #$PR_NUMBER review
- <file:line> — <what changed>
```
Fix fails its check or adds unrelated diff → `git restore`, demote. Never force-push or amend.
### 8. Report
Stdout only. Omit empty sections.
```
PR #<PR_NUMBER> follow-up complete.
Issues created:
- #<N> — <summary>
Applied (commit <sha>):
- <file:line> — <summary>
Out-of-scope suggestions:
- <nit>
Execution order: {#A, #B} → #C
```
Nothing in any bucket: `PR #<PR_NUMBER>: no follow-up issues or suggestions.`

name: implement-op
description: Modify op code to match the manifest-declared interface, making spec tests pass.
---
## Arguments
`op_name`, `manifest_signature`, `source_op`, `source_test` — passed by align-family orchestrator.
## Contract
- **Input**: `op_name`, `manifest_signature`, `source_op`, `source_test`
- **Output**: modified op code + commit + `observations` list (returned to orchestrator)
- **Termination (success)**: `python scripts/validate_manifest.py --check-op <name>` all levels pass + new tests pass.
- **Termination (blocked)**: fix requires changes beyond Op layer. Return `blocked` with reason.
- **Constraint**: must NOT modify `tileops/manifest/`. Must NOT modify tests written by `test-op` in this align-op run (spec contract). MAY update pre-existing tests in `<source_test>` whose call-sites use the legacy API. The parent orchestrator (`align-op`) handles the manifest flip at FLIP_STATUS, bound by the [Status flip carve-out](../../rules/manifest-trust-model.md#status-flip-carve-out). If your implementation needs a contractual-field change to make tests pass, return BLOCKED — do not edit the manifest yourself.
- **Behavioral compatibility**: default param values (from manifest) must produce identical results to the old implementation. The old API shape (e.g., `__init__(M, N)`) is NOT preserved — the manifest defines the target interface.
## Workflow
```mermaid
stateDiagram-v2
[*] --> ANALYZE
ANALYZE --> DIAGNOSE: semantic knowledge extracted
DIAGNOSE --> VALIDATE: gap already resolved (base class fixed by previous op)
DIAGNOSE --> IMPLEMENT: gap exists
IMPLEMENT --> VALIDATE: sub-step completed
VALIDATE --> IMPLEMENT: sub-step failed
VALIDATE --> MARK_DONE: all pass
VALIDATE --> BLOCKED: fix exceeds Op layer scope
MARK_DONE --> COMMIT
COMMIT --> [*]
BLOCKED --> [*]: return blocked to orchestrator
```
## Dual-path policy
Before refactoring a base class, count its subclasses:
```bash
grep -rlE "class\s+[A-Z][A-Za-z0-9]*\s*\(\s*<BaseName>\s*\)" tileops/ops/
```
- **One subclass** (the op being migrated): refactor the base in place. No dual-path.
- **Multiple subclasses**: keep the legacy `__init__` path alongside the new one so unmigrated siblings still pass. Cleanup gate removes the legacy path after all siblings migrate.
Do NOT preemptively migrate siblings to avoid dual-path — that violates per-op scope.
## Steps
### 1. ANALYZE
Read existing code (`source_op`) to extract semantic knowledge:
- What the computation does (the algorithm)
- Where constraints are hardcoded (e.g., `dim=-1`, `reshape(-1, N)`)
- What the generalization path is
Manifest = WHAT (target interface). Existing code = HOW (computation logic). The delta is the work.
This analysis is internal — not persisted.
### 2. DIAGNOSE
Check if the gap still exists. A previous op's migration may have fixed the shared base class.
- Gap resolved → skip to VALIDATE
- Gap exists → proceed to IMPLEMENT
### 3. IMPLEMENT
Decompose into independently verifiable sub-steps. Each sub-step either succeeds or fails with precise location (→ BLOCKED). No retry loops — if a sub-step fails with the same error twice, the task is beyond current scope.
Agent determines sub-steps based on the specific gap. Do not follow a fixed recipe.
### 4. VALIDATE
Run all checks:
```bash
python scripts/validate_manifest.py --check-op <op_name>
python -m pytest <source_test> -v
```
All must pass. If not, return to IMPLEMENT.
### 5. MARK_DONE
Record `observations` — design knowledge discovered during migration:
- Patterns (e.g., "scan ops need transpose, reduction ops reshape")
- Edge cases
- Abstraction opportunities
Do NOT modify manifest or design docs. Observations are returned to orchestrator and surfaced in PR for human review.
### 6. COMMIT
Commit code changes only. Do not commit manifest changes.

name: resolve-tileops
description: Per-round driver of stateful agent-driven review-resolution on a tile-ai/TileOPs PR (developer side). Designed for /loop dynamic mode — re-fires until a terminal action. Outer caller must run preflight.sh once before starting the loop. State persists in `.foundry/runs/{issue-<N> | pr-<PR>}/resolve/`.
---
## Arguments
| Argument | Required | Description |
| ------------- | -------- | -------------------------------- |
| `<PR_NUMBER>` | Yes | TileOPs PR number (e.g. `1133`). |
Resolution work runs in **this agent session** — no external subagent.
## Step 1: Pre-round
```bash
PR=$ARGUMENTS
PRE=$(bash .claude/skills/resolve-tileops/round-pre.sh "$PR") || exit 1
ACTION=$(echo "$PRE" | jq -r .action)
ROUND=$(echo "$PRE" | jq -r .round)
RUN_DIR=$(echo "$PRE" | jq -r .run_dir)
SNAP=$(echo "$PRE" | jq -r .snap_prefix)
MESSAGE=$(echo "$PRE" | jq -r .message)
```
Branch on `ACTION`:
- `terminate-success` / `terminate-diverged` / `terminate-external` /
`terminate-stalled` — write retrospective (see below), print
`MESSAGE`, **return without ScheduleWakeup**.
- `idle` — print `MESSAGE`, ScheduleWakeup with `delaySeconds=180`,
`prompt=/resolve-tileops <PR>`, `reason="PR #<PR> idle — polling"`. Return.
- `continue` — proceed to Step 2.
### Retrospective (terminal actions only)
Write a terse retrospective directly to `$RUN_DIR/retrospective.md` based
on this session's understanding of what happened across the loop's rounds.
Required:
- **Problem** (1–2 lines on core reviewer concerns)
- **Resolution** (`all-addressed` | `partial` | `unresolved`, one line)
Optional (only if substantive):
- **Approach** (1–2 lines on techniques applied)
- **Follow-up** (concrete deferred items, one per line)
Action-oriented; no long prose.
## Step 2: Load context
**Round 1 only** — read into your working context:
- `.claude/skills/resolve-tileops/procedure.md` — triage / fix / reply / resolve threads.
- `.claude/skills/resolve-tileops/criteria.md` — reply formats and hard rules.
Round 2+ rely on session memory.
**Every round** — read this round's inputs:
- `$RUN_DIR/inbox-history/round-NN.md` — this round's inbox guidance,
if any (only present if `inbox.md` was non-empty when round-pre archived it).
- `$SNAP.new-reviews.json`
- `$SNAP.new-inline-comments.json`
- `$SNAP.unresolved-threads.json`
- `$SNAP.ci.json`
- `$SNAP.auto-resolve.json` — JSON action plan from the stale-bot auto-resolver. `resolve[]` lists threads the classifier *planned* to auto-reply + resolve (known bot, anchored to a stale commit, no non-whitelisted participant anywhere in the thread); per-thread outcomes live under `executed.{resolved, reply_failed, resolve_failed}` so consumers can distinguish a planned-and-completed resolve from a planned-but-failed one. `unknown_bot_like[]` and `$RUN_DIR/round-NN.unknown-bot-like.json` flag bot-like logins missing from `known-bots.json` for human triage. `skip[]` lists threads the resolver intentionally left untouched (humans, mixed-author threads, or bots already at HEAD).
## Step 3: Resolve
Apply `procedure.md`. Inbox guidance for this round (if any) overrides
default behavior where they conflict.
Do NOT post a structured trailer in any PR comment — `round-post.sh`
detects round effects from GitHub state.
## Step 4: Post-round
```bash
POST=$(bash .claude/skills/resolve-tileops/round-post.sh "$PR") || exit 1
PUSHED_SHA=$(echo "$POST" | jq -r .pushed_sha)
THREADS_RESOLVED=$(echo "$POST" | jq -r .threads_resolved)
OPEN_AFTER=$(echo "$POST" | jq -r .open_after)
```
Print: `Round $ROUND done — pushed=$PUSHED_SHA, threads_resolved=$THREADS_RESOLVED, open_after=$OPEN_AFTER.`
## Step 5: Self-schedule (only under /loop)
After a real work round, ScheduleWakeup:
- `prompt`: `/resolve-tileops <PR>`
- `delaySeconds`: `180`
- `reason`: `"PR #<PR> resolve round <ROUND> — pushed=<PUSHED_SHA>"`
Outside `/loop`: skip; just return.

- **Reject**: `<conclusion>. <evidence or reasoning>.`
- **Defer**: `Valid point. Out of scope for this PR — <reason>. Will address in follow-up.`
One reply per thread. Resolve every thread that was replied to, regardless of verdict.
### 2. Top-level note (optional, only when something cross-cutting can't fit inline)
```

- Do NOT restate inline replies. If a thread already has the reply, the top-level note must not repeat it.
- No per-file / per-line bullets. Those live inline.
- No GitHub review IDs (`#4181055953`) — meaningless to humans.
- One short paragraph + at most two markdown sections in any top-level note. If you can't fit it, rethink whether it belongs inline.
- All replies in English; concise — conclusion, action, reasoning. No filler.

## Triage each unresolved thread and summary item
For each inline thread's root comment **and** each actionable item from review summaries, classify:
| Verdict | Criteria | Action |
| ---------- | ----------------------------------------------------------------- | ------------------------------------- |
| **Accept** | Feedback is correct and fix belongs in this PR's scope | Fix the code |
| **Reject** | Feedback is incorrect, irrelevant, or based on a misunderstanding | Reply with reasoning |
| **Defer** | Feedback is valid but fix would significantly expand PR scope | Acknowledge, explain why out of scope |
**Bias toward Accept.** Only defer when the fix would:
- Touch files/modules unrelated to the PR's stated purpose.
- Require a design decision not yet made.
- Be large enough to warrant its own review cycle.
Evaluate all feedback on merit, regardless of whether the reviewer is human or bot.
## Apply fixes
For each accepted comment, read the relevant file, understand the context, and make the **minimal** fix. Commit message: `[Chore][<scope>] address review feedback` where `<scope>` comes from the PR title's `[Type][Scope]` pattern (omit `[<scope>]` if the title has none).
## Reply and resolve threads; optional top-level note
### Inline threads (always)
For each thread, reply **inline** then resolve:
```bash
# Reply
gh api "repos/$REPO/pulls/$PR/comments/<root_comment_id>/replies" \
-f body="<reply>"
# Resolve thread
gh api graphql -f query='
mutation($id:ID!) {
resolveReviewThread(input:{threadId:$id}) {
thread { isResolved }
}
}' -f id="<thread_node_id>"
```
### Top-level PR comment (optional)
Skip if every item is covered by an inline reply. Only post when there is something inline can't carry: cross-cutting context, a defer rationale that spans the PR, or a one-line pointer to the fix commit.
```bash
gh api "repos/$REPO/issues/$PR/comments" -f body="<top-level note>"
```
**Deduplicate**: if multiple reviewers (or summary + inline) raise the same point, fix once, reference the same commit in each reply.
Resolve every thread that was replied to, regardless of verdict.

# review-tileops setup
This skill reviews PRs as a GitHub identity distinct from the PR author. The identity is per-developer machine config — it is not in the repo.
## One-time setup
1. Have a second GitHub account (separate from the one you author PRs with).
1. Pick any directory path you like, then authenticate `gh` against it as that account:
```bash
GH_CONFIG_DIR=/path/to/your/reviewer-config gh auth login --hostname github.com
```
1. Export the same path in your shell rc:
```bash
export TILEOPS_REVIEW_GH_CONFIG_DIR=/path/to/your/reviewer-config
```
## Before reviewing each PR
Run once per PR (the loop driver does this automatically; for a manual single-shot review, run it yourself):
```bash
bash .claude/skills/review-tileops/preflight.sh <PR_NUMBER>
```
It verifies the env var, the `hosts.yml`, and that the reviewer login is distinct from the PR author. The skill itself does no preflight — it assumes this has passed.
## If preflight errors
Each error message names the next command to run. Follow it.

name: review-tileops
description: Single-shot review of a tile-ai/TileOPs PR as a separate GitHub identity from the PR author. Manual / interactive — for autonomous multi-round review until APPROVE, run `bash .claude/skills/review-tileops/loop.sh <PR>` instead.
---
## Input
`$ARGUMENTS`: integer PR number in `tile-ai/TileOPs`. E.g. `1122`.
## Step 0: Preflight
```bash
bash .claude/skills/review-tileops/preflight.sh <PR> || exit 1
export GH_CONFIG_DIR="$TILEOPS_REVIEW_GH_CONFIG_DIR"
```
## Step 1: Gather inputs
```bash
gh pr view <PR> --repo tile-ai/TileOPs \
--json number,title,body,files,headRefOid,state
gh pr diff <PR> --repo tile-ai/TileOPs
```
Parse the title's first two bracket tokens — `[type][scope] description`. Look both up in `loading.yaml`:
- Always load entries under `always:`.
- For each token, if it appears as a key under `match:`, load the listed checklist files.
- Multi-match across the two tokens → union. Both unmatched → no domain checklist; rely on general judgment.
Read each loaded checklist file under `.claude/review-checklists/`, plus `criteria.md`. Skim unresolved review threads (`gh api graphql … reviewThreads`), recent non-reviewer comments (`gh api repos/.../issues/<N>/comments` and `…/pulls/<N>/comments`), and CI status (`gh pr checks <N>`) if relevant to the diff.
## Step 2: Execute the review
Follow `procedure.md` end to end. Submit one atomic review at the end.

### 1. Submit
```bash
gh api repos/tile-ai/TileOPs/pulls/<N>/reviews \
-f event="<EVENT>" \
-f body="<SUMMARY>" \
-f 'comments=[{"path":"<file>","line":<line>,"body":"<comment>"}, ...]'
```
`<EVENT>`: `REQUEST_CHANGES` if any blocking issue, `APPROVE` if clean, `COMMENT` for non-blocking questions only.
### 2. Inline format
```
<what is wrong and why> → <what to change>
```
One comment per issue. Name the function, variable, or pattern. The reader is an agent that executes fixes literally.
### 3. Summary format (markdown)
The summary is for what does **not** fit in an inline comment. Per-file issues belong inline (§2), not in a summary list. Omit empty sections.
```
### Overall
<one line: top risk + next step. No event echo, no item list.>
### Cross-cutting concerns
- <pattern spanning multiple files — only what an inline comment can't carry>
```
Hard rules:
- Do NOT restate inline comments. If a finding is already inline, it must not appear in the summary.
- Per-file/per-line items go in the `comments=[...]` array of §1, never in the summary body.
- Clean PR: one line, `Clean — no issues.`
### 4. Hard rules
- Do not comment outside the PR diff.
- Do not invent issues on a clean PR.
- No eager design-doc reads — only when a guard names a doc AND the diff makes that item ambiguous, or the divergence trigger fires.
- All review text in English.
- All `gh` calls run with `GH_CONFIG_DIR` already exported by the caller. Repo is fixed at `tile-ai/TileOPs`.

# PR title → review-checklists mapping.
#
# A TileOPs PR title always has the form `[type][scope] description` (the
# scope bracket is optional but conventional). The loop / single-shot
# review checks BOTH bracket tokens against `match` below; any token that
# matches contributes its checklists. Multi-match across the two tokens

#
# Add a new entry here when a new type or scope earns a dedicated

**Free-form review (step 2) is the primary review step.** Project-specific guards (step 4) are a regression net applied last — they exist because the free-form pass is fallible at known classes of issue, NOT because they replace it. Skipping or shortening step 2 to lean on guards is a failure mode.
1. **Read every changed source file in full.** The diff alone lacks surrounding context.
1. **Free-form review (primary).** Flag: logic errors, edge cases, API misuse, races, resource leaks, broken invariants, error-handling gaps, perf regressions, dead code, unclear names, missing tests. This is where the bulk of your reasoning belongs.
1. **Triage unresolved review threads.** For each thread, judge whether the developer's latest change resolves the concern. If unresolved, surface as an inline comment.
1. **Apply each loaded project-specific guard (last, supplement).** Walk its bullets against the diff. Add anything new to the step-2 findings.
1. **Approval-gate decision.** If your draft event is `APPROVE`: read `.claude/review-checklists/approval-gate.md` and run every applicable check (each item self-scopes to the diff per the file's preamble). Downgrade to `REQUEST_CHANGES` if any fail.
1. **Compose inline comments** per `criteria.md` §2 — one per issue, format `<what is wrong and why> → <what to change>`. Name the function, variable, or pattern.
1. **Compose the summary** per `criteria.md` §3. Omit empty sections. A clean PR gets a single line: `Clean — no issues.`
1. **Submit one atomic review** per `criteria.md` §1, with the inline comments in the `comments=[…]` array. Follow `criteria.md` §4 hard rules.

# round-post.sh — post-codex hook for the review loop.
#
# Implements Rule 2 (same-path 5-strike monitor): track per-path

#
# Inputs (env or positional, env wins):

# ROUND — integer round number that just finished.
# COMMENTS_JSON — path to round-NN.codex-blockers.json (the post-
# codex snapshot of review comments authored by
# REVIEWER_LOGIN this round; used as the source of
# blocker paths). The pre-codex
# round-NN.new-review-comments.json is the WRONG

# round-pre.sh — pre-codex hook for the review loop.
#
# Implements Rule 1 (same-SHA APPROVE skip): if any prior round in
# this loop run already produced an APPROVE on the *current* HEAD
# sha, skip the codex invocation entirely. Reuse the prior APPROVE
# verbatim by writing a marker round-NN.json that carries the same
# codex_event/blockers as the prior round and points back at it
# via the "approve_reused_from" field.
#
# Inputs (env or positional, env wins):
# RUN_DIR — review/ root for this loop run; must contain rounds/.
# NEXT_ROUND — integer round number about to run (e.g. 5).
# HEAD_SHA — full git sha of the PR HEAD this round would review.
# LATEST_ISSUE_ID — current max id of any non-reviewer top-level PR
# (issue) comment.
# LATEST_REVIEW_ID — current max id of any non-reviewer review/inline
# comment (incl. thread replies).
# Each is independent. When supplied, the reuse
# decision requires the prior approving round's
# counterpart watermark to match. A caller may
# supply only one — the unsupplied dimension is
# not constrained. If a NEW human comment of
# either kind landed on the same SHA after the
# prior APPROVE, the matched watermark mismatches
# and this hook returns "proceed" so codex re-
# reviews and ingests the comment. When BOTH are
# absent or empty, the watermark guard is skipped
# entirely (legacy behavior, used by tests that
# pre-date the watermark fields).
#
# Positional fallback:
# round-pre.sh <RUN_DIR> <NEXT_ROUND> <HEAD_SHA> [LATEST_ISSUE_ID] [LATEST_REVIEW_ID]
#
# Output:
# - exit 0 + stdout "skip" → loop should skip codex; round-NN.json is
# already written by this script.
# - exit 0 + stdout "proceed" → no prior APPROVE on this SHA, OR a
# recoverable condition was hit (missing
# args, missing rounds dir, malformed
# prior round file, etc.). The loop's
# ``|| echo "proceed"`` fallback expects
# this contract: round-pre.sh is a
# monitor and MUST NOT exit non-zero on
# recoverable conditions, otherwise

# provided, we MUST iterate ALL same-SHA APPROVE candidates and reuse
# the one whose recorded watermarks match every supplied LATEST_*_ID
# (per-dimension; unsupplied dimensions are unconstrained). Breaking

# even though round 6 is a perfectly reusable APPROVE.

name: scaffold-op
description: Scaffold a new T2 (L1-direct) Op file from a single `tileops/manifest/` entry by following the 7-step playbook in docs/design/ops-design.md. Emits the 17 scaffold slots (S1-S7, S12-S21); leaves family-specific protocol variables, optional hooks, and kernel implementations to downstream skills.
---
## Arguments
`op_name` (positional) — manifest key for the op to scaffold, equal to the target `cls.__name__` (e.g. `CumsumFwdOp`).
## Contract
- **Input**: `op_name` must be present in [`tileops/manifest/`](../../../tileops/manifest/) with `status: spec-only` and a non-empty `source.kernel_map`. `source.kernel_map` is manifest-level source of truth for Op→Kernel dispatch and cannot be derived by the scaffold (dispatch keys are kernel-internal conventions); adding it for a spec-only entry is a prerequisite manifest PR.
- **Output**: new file at the exact path declared by manifest `source.op` (e.g., `tileops/ops/reduction/cumsum.py`), containing the 17 scaffold slots; one-line `from .<module> import <ClassName>` added to the package `__init__.py` at that path's parent directory (e.g., `tileops/ops/reduction/__init__.py`) with a matching `__all__` entry. Note: the filesystem package directory (parent of `source.op`) is not always the same as the manifest `family` field — for example, `CumsumFwdOp` has `family: scan` but lives under `tileops/ops/reduction/`. Always key paths off `source.op`, never off `family`. Plus a side-artefact at `.foundry/plan/<op_name>/plan.json` carrying the DRY_RUN self-audit (not tracked in git).
- **Termination (success)**: `python scripts/validate_manifest.py --check-op <op_name>` reports **no errors** for this op. Warnings are allowed and passed through to the final summary.
- **Termination (blocked)**: any validator error for `op_name` that the scaffold cannot fix by re-reading the playbook's slot rules. Do NOT commit; report with the failing rows from the validator.
- **Constraints**:
- MUST NOT emit family-specific protocol variables (`_op_kind`, `_kernel_key`, `_kernel_cls`, `_kernel_handles_padding`, `_op_name`, `kernel_cls`).
- MUST NOT emit optional hooks (`_pad_value`, `_validate_dim`, `_pre_kernel`, `_post_kernel`, `_cache_key` override).
- MUST NOT implement the kernel itself.
- MUST NOT modify `tileops/manifest/`, tests, benchmarks, or any existing op file.
- MUST NOT extend scope to a T1 (family-base) subclass — the scaffold is T2 only.
## Workflow
```mermaid
stateDiagram-v2
[*] --> READ
READ --> PRE_CHECK
PRE_CHECK --> DRY_RUN
PRE_CHECK --> BLOCKED: precondition failed
DRY_RUN --> EMIT: plan.json written
EMIT --> REGISTER
REGISTER --> VALIDATE
VALIDATE --> REPORT
VALIDATE --> BLOCKED: validator error or §1 drift
REPORT --> [*]
BLOCKED --> [*]
```
`DRY_RUN` writes `plan.json` to freeze manifest-sourced facts before codegen. `VALIDATE` diffs the emitted file against `plan.json` §1 — any drift is a skill bug, not a manifest issue.
## Slot scope
Emit exactly the 17 slots in [`ops-design-reference.md § Slot Rules`](../../../docs/design/ops-design-reference.md#slot-rules): S1–S7, S12–S21. S8–S11 are reserved for T1 thin-wrapper subclasses and skipped.
Out of scope — leave empty:
| Item | Reason |
| ----------------------------------------------------------------------------- | -------------------------------------------------------- |
| Family protocol vars (`_op_kind`, `_kernel_key`, `_op_name`, …) | Kernel-dispatch convention; not in manifest |
| Optional hooks (`_pad_value`, `_validate_dim`, `_pre_kernel`, `_post_kernel`) | Op-specific business logic |
| `_cache_key` override | Recommended under dynamic shapes; depends on kernel math |
| Kernel implementations | Owned by kernel skill |
| Tests / benchmarks | Owned by `test-op` / `bench-op` |
These gaps surface as `NotImplementedError` or validator warnings; downstream skills fill them.
## Steps
### 1. READ
Load the manifest entry for `op_name`:
Before running the snippet, substitute `<op_name>` with the requested manifest key (the skill's positional argument — agent literal substitution, not shell interpolation):
```bash
python - "<op_name>" <<'PY'
import sys
from tileops.manifest import load_manifest
op_name = sys.argv[1]
entry = load_manifest()[op_name]
print(entry)
PY
```
Extract: `family`, `status`, `signature.inputs`, `signature.outputs`, `signature.params`, `signature.static_dims`, `signature.shape_rules`, `source.kernel_map`, `source.op`, `source.kernel`, `roofline.vars`, `roofline.flops`, `roofline.bytes`.
Derive the target file path from `source.op` (e.g. `tileops/ops/reduction/cumsum.py`). The **filesystem package directory** is `source.op`'s parent (e.g. `tileops/ops/reduction/`). Do not use the manifest `family` field to compute paths — it is a semantic label, and some ops have `family` distinct from their filesystem parent (e.g., `CumsumFwdOp` has `family: scan` but lives under `reduction/`). Module filename is `source.op`'s basename without `.py`.
### 2. PRE_CHECK
- `op_name` present in `tileops/manifest/` → proceed; otherwise BLOCKED ("op not in manifest").
- `status` field explicitly set to `spec-only` → proceed; `status: implemented` → BLOCKED ("op already implemented; use implement-op to migrate"); missing `status` or any other value → BLOCKED ("manifest entry must declare a valid top-level `status`; the validator treats `status` as required").
- `source.kernel_map` declared and non-empty → proceed; missing or empty → BLOCKED ("manifest entry needs `source.kernel_map` before scaffolding — add the dispatch map in a separate manifest PR per the trust model; the scaffold cannot invent dispatch keys because they are kernel-internal conventions"). Note: per `docs/design/manifest.md`, `source.kernel_map` is only required when `status: implemented`, so many existing `spec-only` entries lack it — these are the cases that need the manifest-PR prerequisite before scaffolding can run.
- Every value in `source.kernel_map` resolves to an importable symbol → proceed; otherwise BLOCKED ("kernel class not found at expected path").
- Target file `source.op` does NOT exist → proceed; exists → BLOCKED ("target file already present; scaffold would overwrite").
BLOCKED terminations return without writing any file.
### 3. DRY_RUN
Write `.foundry/plan/<op_name>/plan.json` with three sections:
| Section | Diffed at VALIDATE? | Content |
| --------------------- | ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `locked_facts` (§1) | yes (hard error on drift) | Verbatim manifest extraction (op_name, class_name, family, module_path, kernel_imports, kernel_map, init_kwargs, forward_inputs/outputs, dtype_unions, dtype_combos, shape_rules, static_dims, roofline) |
| `agent_notes` (§2) | no | Judgement calls (docstring, kernel ctor signature observed, helper state, forward reshape strategy, codebase refs consulted) |
| `open_questions` (§3) | no | Ambiguities tagged `needs_doc_fix` / `needs_manifest_fix` / `needs_human_decision`; surfaced in REPORT, never block |
Always proceed to EMIT. Empty `open_questions` is fine.
Skeleton:
```json
{
"locked_facts": {
"op_name": "CumsumFwdOp",
"module_path": "tileops/ops/reduction/cumsum.py",
"kernel_map": {"cumulative_fwd": "CumulativeKernel"},
"init_kwargs": [{"name": "dim", "source": "signature.params.dim", "type": "int", "default": -1}],
"forward_inputs": ["x"],
"static_dims": {"N": "x.shape[dim]"},
"roofline": {"flops": "M * N", "bytes": "2 * M * N * elem_bytes"}
},
"agent_notes": {"docstring_summary": "...", "kernel_ctor_signature_observed": "..."},
"open_questions": [{"tag": "needs_human_decision", "topic": "...", "detail": "..."}]
}
```
### 4. EMIT
Follow [`docs/design/ops-design.md` § Scaffolding an Op from a Manifest Entry](../../../docs/design/ops-design.md#scaffolding-an-op-from-a-manifest-entry) Steps 1-7 in order. For each scaffold slot, read the authoritative rule at `docs/design/ops-design-reference.md#slot-sN` before emitting.
Key slot pointers (follow the reference, do not re-derive):
| Playbook step | Slots | Reference anchor |
| ------------- | -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Step 1 | S1, S2, S3, S4 | [S1](../../../docs/design/ops-design-reference.md#slot-s1)-[S4](../../../docs/design/ops-design-reference.md#slot-s4) |
| Step 2 | S5, S6, S7 | [S5](../../../docs/design/ops-design-reference.md#slot-s5)-[S7](../../../docs/design/ops-design-reference.md#slot-s7) |
| Step 3 | S21, S12, S13 | [S21](../../../docs/design/ops-design-reference.md#slot-s21), [S12](../../../docs/design/ops-design-reference.md#slot-s12), [S13](../../../docs/design/ops-design-reference.md#slot-s13) |
| Step 4 | S14, S15, S16 | [S14](../../../docs/design/ops-design-reference.md#slot-s14)-[S16](../../../docs/design/ops-design-reference.md#slot-s16) |
| Step 5 | S17, S18 | [S17](../../../docs/design/ops-design-reference.md#slot-s17), [S18](../../../docs/design/ops-design-reference.md#slot-s18) |
| Step 6 | S19 | [S19](../../../docs/design/ops-design-reference.md#slot-s19) |
| Step 7 | S20 | [S20](../../../docs/design/ops-design-reference.md#slot-s20) |
If a slot's rule is ambiguous for the given manifest entry (e.g. multi-kernel `kernel_map`, multiple independent dtype axes, fixed-rank vs arbitrary-rank branching), STOP and surface the ambiguity in the final report instead of guessing. Do not expand scope.
### 5. REGISTER
Append to the `__init__.py` at `dirname(source.op)`:
| File style | Action |
| ---------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| Grouping comments `# --- <KernelClassName> ops ---` (e.g. `tileops/ops/reduction/__init__.py`) | Place import under matching kernel block; create a new block (alphabetical) when no existing block references the kernel |
| Flat imports (e.g. `tileops/ops/norm/__init__.py`) | Append alongside existing imports following file's ordering convention; do NOT introduce grouping comments |
Add matching `<ClassName>` to `__all__`, preserving any existing sectioning.
### 6. VALIDATE
**(a) §1 post-check** — diff `plan.json.locked_facts` against the emitted artefacts:
- Parse `source.op` with `ast`: extract class name, base, imports, `__all__`, `__init__` kwargs (names / defaults / types in order), `forward` params, `default_kernel_map` dict, `_static_axes`.
- Parse `dirname(source.op)/__init__.py` with both `ast` (presence + `__all__` membership) and raw text (block placement under `# --- <KernelClassName> ops ---` when the file uses grouping comments; skip placement check on flat-style files).
- Any `locked_facts` field mismatch → BLOCKED `§1 drift: <field>`. Skill deviated from its own contract; fix the emitted file (or revert and restart DRY_RUN if the plan was wrong). Do NOT edit `plan.json` to match.
**(b) Manifest validator**:
```bash
python scripts/validate_manifest.py --check-op <op_name>
```
`--check-op` runs L0–L4 even on `status: spec-only`. Classify output:
- **ERROR** → BLOCKED. Copy the row to REPORT. For L2 / L3 parity failures, re-check the emitted `_infer_output_shapes` / `_validate_dtypes` against manifest `shape_rules` / `dtype_combos` first — likely a mis-emit.
- **WARNING** → pass through.
Never edit the manifest to silence an error. No `parity_opt_out` escape hatch. Demote to `status: spec-only` only when the implementation genuinely cannot conform.
### 7. REPORT
```
Status: SUCCESS | BLOCKED
Op: <op_name>
File: <path> (<lines>)
Package registration: <parent-of-source.op>/__init__.py (+1 import, +1 __all__)
Plan: .foundry/plan/<op_name>/plan.json
§1 drift: <none | <field>: <plan> vs <emitted>>
Validator: <N errors, M warnings>
<if BLOCKED, list each blocking error row verbatim>
Warnings:
- <warning>
Open questions (from plan.json §3):
needs_doc_fix: - <topic>: <detail>
needs_manifest_fix: - <topic>: <detail>
needs_human_decision: - <topic>: <detail>
Not filled (downstream hand-off):
- Kernel implementation
- Optional hooks (family-specific)
- Family protocol variables (family-specific)
- _cache_key override (recommended under dynamic shapes)
```
SUCCESS → commit `[Feat][OPS] scaffold <op_name>`. BLOCKED → leave tree dirty, return. `plan.json` persists either way.
## Non-goals
- Not a codegen engine — agent procedure. The input/output contract is codegen-compatible.
- Not a migration driver — `status: implemented` ops use `implement-op` / `align-family`.
- Not a kernel scaffold.
If a slot rule is internally inconsistent or cannot be followed mechanically, file a doc issue and BLOCK; do not invent slot behaviour.

name: test-op
description: Write tests for the target spec using PyTorch as ground truth, verify they fail on current code.
---
## Arguments
`op_name`, `manifest_signature`, `pytorch_equivalent`, `source_test` — passed by align-family orchestrator.
## Contract
- **Input**: `op_name`, `manifest_signature`, `pytorch_equivalent`, `source_test`
- **Output**: updated test file + commit
- **Constraint**: must NOT modify op implementation. Test-only.
- **Trust model**: this agent must be a different invocation from implement-op.
## Workflow
```mermaid
stateDiagram-v2
[*] --> READ_SPEC
READ_SPEC --> ASSESS_EXISTING: manifest signature + pytorch_equivalent loaded
ASSESS_EXISTING --> WRITE_TESTS_EXTEND: semantic extension — old assertions still valid
ASSESS_EXISTING --> WRITE_TESTS_REPLACE: semantic update — old assertions incompatible
WRITE_TESTS_EXTEND --> VERIFY_FAILS: new tests added, existing kept
WRITE_TESTS_REPLACE --> VERIFY_FAILS: outdated tests deleted, new tests written
VERIFY_FAILS --> DONE: confirmed failing on current code
VERIFY_FAILS --> DONE_SKIP: tests already pass (base class fixed by previous op)
```
## Steps
### 1. READ_SPEC
Read `manifest_signature` to determine target interface:
- `signature.inputs` → `forward()` params (tensor inputs)
- `signature.params` → `__init__()` params (configuration)
- This follows Op design convention in `docs/design/ops-design.md`. The manifest is the source of truth.
### 2. ASSESS_EXISTING
Read current test file (`source_test`). Compare existing test construction and assertions against the new spec:
- Old assertions still valid under new spec → **semantic extension** (keep existing tests, add new ones)
- Old assertions incompatible (e.g., construction API changes from `Op(M, N)` to `Op(dim)`) → **semantic update** (delete outdated tests, write replacements)
### 3. WRITE_TESTS
Write tests using PyTorch reference as ground truth:
```python
# Example — derive from manifest, don't copy this literally
expected = torch.nn.functional.softmax(x, dim=dim)
actual = op(x)
torch.testing.assert_close(actual, expected, rtol=rtol, atol=atol)
```
- Use `TestBase` pattern (`gen_inputs()` + `ref_program()` + `check()`). Follow `docs/design/testing.md`.
- Write tests in `source_test` file. No new files.
- For integer outputs (manifest `outputs.*.dtype` is int type), use `torch.equal` for exact comparison.
- Parameterize: supported dtypes (FP16, BF16), representative dim values, keepdim True/False where applicable.
### 4. VERIFY_FAILS
Run the new tests against current code:
```bash
python -m pytest <source_test> -v
```
New tests must **fail** on current code. Construction-time error counts (e.g., current `__init__` doesn't accept `dim`).
**DONE_SKIP**: if tests already pass (base class fixed by a previous op's migration), this is valid. Proceed to implement-op.

<!--
INSTRUCTIONS FOR THE AGENT (do not copy into the PR body).
Layout principle: one section per op, one table per section, TileOPs and
baseline side-by-side on the same row so readers can compare without
mentally joining two tables.
Filling in the template below:
- One row per measurement (shape × dtype) within an op's table.
- Baseline column header names the baseline (`torch (ms)`, `FA3 (ms)`,
`triton (ms)`). Don't write a generic "Baseline". Multiple baselines →
add more columns and more Speedup columns (`vs torch`, `vs FA3`).
- Speedup is always present — it's the first number readers look for.
Format `4.96×`, two decimals, computed as baseline_ms / tileops_ms.
- Throughput column: show ONE — TFLOPS for compute-bound ops (matmul,
attention), BW (TB/s) for memory-bound ops (reductions, elementwise,
norms). Pure data movement → BW only. Don't list both.
- Show throughput for TileOPs only; baseline's absolute throughput is
noise once Speedup is given.
- Drop the Shape column if the op only varies dtype; in that case put
the fixed shape in the section header (e.g. `### {OpName} (4096, 4096)`)
so the benchmark's scale stays visible. Never put autotune config
(`block_m`, `threads`) in the table — implementation detail.
- **Preserve the original shape tuple — never flatten to a single
element count.** Write `(4096, 4096)` for a 2D input, `(2, 4096, 128)`
for a 3D one, and `(4194304,)` (or `(4M,)`) for a genuinely 1D op.
A bare `4M` loses dimensionality: readers can't tell `(4M,)` from
`(2K, 2K)` from `(64, 64K)`, yet those have very different access
patterns. Use `K`/`M` only inside a tuple to keep large numbers
readable, never to replace it.
- Environment block goes once at the top, not per op.
- Takeaways = conclusions, not data repetition. Wins, losses with a brief
reason (not blocking), dtype/shape patterns.
Bench-file authoring rules (apply when writing benchmarks/ops/*.py, NOT
copied into the PR body):
- All dtypes in `SUPPORTED_DTYPES`; ≥3 shapes per op, include non-pow2
if supported.
- Shapes must map to real model geometry. Default LLaMA sizes:
hidden ∈ {4096, 5120, 8192}, intermediate ∈ {10240, 11008, 14336,
20480, 28672}, seq_len ∈ {2048, 4096}.
- Every benchmark must record at least one baseline. Tags: `tileops`
(TileOPs implementation; required exactly once per config; variants
like `tileops-lut` also count) and `torch` / `FA3` / `fla` / `triton`
(baselines for comparison). External baselines may be conditional,
but the else branch must fall back to torch — never silently skip.
- `BenchmarkReport.record()` first arg must be the Op object, never a
string literal.
-->
## Benchmark
**Environment**: \{GPU}, CUDA \{ver}, PyTorch \{ver}, TileLang \{ver}
### \{OpName}
| Shape | dtype | TileOPs (ms) | \{baseline} (ms) | Speedup | BW (TB/s) |
| ----- | ----- | ------------ | ---------------- | ------- | --------- |
<!-- Repeat one ### section per op. Drop the Shape column if the op only
varies dtype. Swap `BW (TB/s)` for `TFLOPS` on compute-bound ops.
Shape values are tuples: `(4096, 4096)`, `(2, 4096, 128)`, `(4M,)`. -->
**Takeaways:** {wins · losses with brief reason · dtype/shape patterns}
**Command:** `PYTHONPATH="$PWD" python -m pytest benchmarks/ops/bench_{op}.py -v`

# Issue Body Sections
Structural contract for the issue body — the template and per-section rules below are what the pipeline parses. Constraints authoring policy (work-shape declarations, defaults) lives in [docs/design/trust-model.md §Issue-authoring](../../docs/design/trust-model.md#issue-authoring-declaring-scope).
## 1. Template
Copy verbatim. Replace each `{...}`. Keep all five top-level sections.
```markdown
## Description
### Symptom / Motivation
{what is observed or motivates the change}
### Root Cause Analysis
{file paths, logic errors, missing features — "N/A" for feature requests}
### Related Files
{key files, functions, or configs}
## Goal
{concrete objective}
## Plan
<!-- type: {proposal | fixed} -->
1. {at least one step}
## Constraints
- {one bullet per constraint or scope declaration — see trust-model.md §Issue-authoring for the three work-shape forms}
## Acceptance Criteria
- [ ] Modified files pass unit tests
- [ ] {additional criteria as needed}
```
## 2. Per-section rules
| Section | Required form |
| ------------------- | -------------------------------------------------------------------------------------------------- |
| Description | Three subsections (`Symptom / Motivation`, `Root Cause Analysis`, `Related Files`), each non-empty |
| Goal | Non-empty single-paragraph objective |
| Plan | `<!-- type: -->` comment (value `proposal` or `fixed`) plus at least one step (`- ` or `1.`) |
| Constraints | At least one list item (`- `) |
| Acceptance Criteria | At least one checkbox, including `- [ ] Modified files pass unit tests` |
## 3. Cross-references
- Constraints authoring policy: [docs/design/trust-model.md §Issue-authoring](../../docs/design/trust-model.md#issue-authoring-declaring-scope)
- Reviewer-side criteria: [.claude/review-checklists/pre-review.md](../../.claude/review-checklists/pre-review.md)

KEEP IT SHORT. Reviewers read PRs to learn WHAT changed and HOW to verify it.
- Summary: 3–5 bullets, one line each. No prose paragraphs.
- Do NOT recount the development process (reviewer rounds, follow-up issues filed,
prior commits reverted, design rationale that already lives in the linked issue).
- Do NOT restate the linked issue's motivation; "Closes #N" already links it.
- One short paragraph of cross-cutting context is fine when bullets can't carry it.

# Pre-Create Checks
## 1. PR title pre-flight validation
**HARD GATE.** Validate the PR title locally against the same source of truth that CI uses, **before** calling `gh pr create`. This guarantees the `validate-pr-title` required check cannot fail.
```bash
source .claude/conventions/types.sh
TITLE="[{{Type}}] {{Description}}" # substitute your actual title
if [[ ! "$TITLE" =~ $COMMIT_MSG_PATTERN ]]; then
echo "BLOCKED: title does not match CI pattern: $TITLE"
echo "Pattern: $COMMIT_MSG_PATTERN"
fi
```
**If validation fails:** fix the title and re-validate. Do NOT proceed to `gh pr create`.
## 2. Test node delta
**Skip entirely** if PR does not modify files under `tests/`.
If PR adds or modifies test files:
```bash
git fetch upstream main --quiet
python scripts/test_node_delta.py --base upstream/main
```
The script auto-detects changed test files via `git diff`. If auto-detect fails (e.g. in a worktree), pass files explicitly:
```bash
python scripts/test_node_delta.py --base upstream/main tests/ops/test_<name>.py
```
**Interpreting output:**
- **No growth on existing files** → nothing to report.
- **Growth on existing files** → include script output and one-line justification in PR body under `## Test node delta`.
- **New test files only** (delta shows "all N nodes from new files") → no delta report needed.
**SOFT GATE:** Does not block PR creation, but missing justification will be flagged during review (per [`.claude/domain-rules/testing-budget.md`](../../.claude/domain-rules/testing-budget.md)).

## Parent Issue
<!-- Link to the main tracking issue for this operator using #IssueID -->
Part of #
## Task Type
<!-- Please check the relevant component for this sub-issue -->
- [ ] **Manifest / Spec** (required for any public Op)
- [ ] **Kernel / Op Implementation**
- [ ] **Correctness Tests / Workloads**
- [ ] **Benchmark / Performance**
## Description
<!-- Detailed description of what needs to be implemented in this step -->
## Checklist
<!--
Refer to:
- docs/design/manifest.md for manifest fields and validation levels
- docs/design/ops-design.md for Op/Kernel implementation rules
- docs/design/testing.md for tests, workloads, and benchmark structure
- docs/design/roofline.md for roofline authoring and benchmark consumers
-->
- [ ] Public Op has a `tileops/manifest/` entry (or updates an existing entry).
- [ ] Manifest `signature` declares inputs, outputs, params, shape rules, and dtype coverage.
- [ ] Manifest `workloads` declare benchmark shapes/dtypes; unit-test edge cases are not generated from manifest workloads.
- [ ] Manifest `roofline` is present and consumable by `op.eval_roofline()`.
- [ ] Manifest `source` declares kernel, op, test, bench, and `source.kernel_map` when dispatching kernels.
- [ ] Op constructor, `forward()`, and `default_kernel_map` match the manifest entry.
- [ ] Tests use an independent reference implementation and cover relevant FP16/BF16 and edge cases.
- [ ] Benchmarks consume manifest workloads and record at least one non-`tileops` baseline unless explicitly justified.
- [ ] PR title and commits follow the current `[Feat][Scope]` / `[Perf][Scope]` / `[Fix][Scope]` convention.
- [ ] Implementation follows **Google Python Style** for code and docstrings.

Trim the persistent bind-mounted /ci-cache (compiled-kernel / triton / pip
caches and the tilelang autotuner cache) on self-hosted CI runners. Fails
fast if the cache volume is still near full after reclaim, so downstream
steps report disk pressure clearly instead of a cryptic mkdir error.

the bind-mounted /ci-cache runner cache layout.
Do NOT include atomic cache roots here (see atomic-cache-dirs); file-
level trim on an atomic root can produce a half-dead "directory exists
but sentinel missing" state that crashes downstream consumers.

atomic-cache-dirs:
description: >
Newline-separated list of cache directory roots whose first-level
subdirectories are *atomic units*: consumers assume "directory exists
=> contents complete" and the subdir is only valid when the sentinel
file (best_config.json, hardcoded) is present. These roots get two
passes instead of file-level trim:
1. Unconditional sentinel-repair: remove any first-level subdir
missing the sentinel (self-heals half-dead state from prior runs).
2. Age-based atomic-trim: if the newest file in a first-level subdir
is older than cache-age-days, delete the whole subdir — never
individual files inside it.
Default targets the tilelang autotuner cache, which stores per-shape
tuning artefacts alongside a best_config.json sentinel.

Sentinel-repair on those roots still runs unconditionally (it self-heals
half-dead state and is cheap). Callers that run on every PR should opt
out of the destructive whole-subdir trim so it only runs via the daily
runner-maintenance.yml job; co-locating it on the per-PR path evicts
autotuner entries the next PR would otherwise reuse.

# reclaim_cache.sh — cache-reclaim primitives used by the
# .github/actions/reclaim-runner-disk composite action.
#
# The action.yml composite used to embed all reclaim logic inline, which
# meant the cache-trim paths could only be exercised on a self-hosted
# runner. That made it impossible to catch regressions at PR time; a bad
# trim rule only surfaced after merge when it had already corrupted the
# live cache. This script exposes the trim primitives as
# pytest-driveable subcommands so tests/test_reclaim_action.py can
# validate behaviour against a tmp_path fixture.
#
# The core safety invariant this script enforces is that some cache
# roots (notably /ci-cache/tilelang/autotuner) store
# *atomic* first-level subdirectories: consumers assume "directory
# exists => contents complete" and the directory is only valid if the
# sentinel file (best_config.json) is present. File-level `-mtime`
# trimming on these roots can delete the sentinel while leaving the
# rest of the directory in place, producing a half-dead state that
# crashes the next consumer. The atomic-trim and sentinel-repair
# subcommands here operate at whole-subdir granularity and never touch
# individual files inside an atomic root.
#
# Subcommands:
#
# sentinel-repair <root> [<root>...]
# For each atomic root, delete any first-level subdirectory that
# does not contain ${SENTINEL_FILENAME:-best_config.json}. This
# self-heals half-dead state left by older reclaim passes.
#
# atomic-trim <age-days> <root> [<root>...]
# For each atomic root, compute the newest file mtime anywhere
# inside each first-level subdirectory. If that mtime is older
# than <age-days> days, delete the whole subdirectory. Never
# trims individual files inside atomic roots.
#
# trim-files <age-days> <root> [<root>...]
# File-level `-mtime +N -delete` trim for non-atomic cache
# roots, followed by empty-directory cleanup. This is the legacy
# behaviour used for /ci-cache/triton, /ci-cache/pip, etc.
#
# All subcommands are idempotent, tolerate missing roots (skipped
# silently), and never exit non-zero for per-directory errors so a
# transient `rm` failure cannot abort the whole reclaim step.

# CI runner image
Multi-stage image for the self-hosted GPU runner. It bakes a tilelang wheel (compiled once
from a pinned commit, or installed from a PyPI release) plus the test/benchmark stack onto a
public CUDA base, so CI never recompiles tilelang per PR.
Built **manually on a GPU host** (needs `nvcc`), then pushed to `ghcr.io`. It is **not**
built in CI.
## Prerequisites
- An NVIDIA GPU host with a CUDA 12.9-capable driver and `nvcc`.
- Docker with BuildKit enabled (`DOCKER_BUILDKIT=1`).
- Run from the **repository root** — the build context must contain `constraints.txt`,
`scripts/ci/verify_runtime_stack.py`, and `.github/runner/entrypoint.sh` (the Dockerfile
copies all three).
## Build
Provide tilelang one of two ways — pass **exactly one** of these build-args:
- **main commit**: `--build-arg TILELANG_GIT_SHA=<commit>` — shallow-fetches and compiles that
commit. The Dockerfile carries no commit literal; the commit you pass is the single source
of truth, and the image tag records it.
- **release**: `--build-arg TILELANG_VERSION=<version>` — `pip install tilelang==<version>`.
```bash
# from the repository root (main-commit mode)
DOCKER_BUILDKIT=1 docker build \
-f .github/runner/Dockerfile \
--target final \
--build-arg TILELANG_GIT_SHA=65dbc9837beedf6882a40a08e18ea571d92fd6a5 \
-t ghcr.io/tile-ai/tileops-runner:65dbc98 \
.
```
Tag with the tilelang commit's **short SHA** (`:65dbc98`). If you rebuild the same commit,
add a numeric suffix (`:65dbc98-2`).
## Roll out an updated runner image
Changes to this Dockerfile are not picked up by CI automatically. After a Dockerfile change
lands, rebuild and tag the image from a GPU host using the build command above, then push it:
```bash
docker push ghcr.io/tile-ai/tileops-runner:<new-tag>
```
Then redeploy the self-hosted runner launcher to use the new tag (maintainer task, done
outside this repository). Merging the TileOPs PR only changes the image recipe; the live
self-hosted runners keep using their existing image until that manual rollout is done.
### Build args
| Arg | Default | Purpose |
| ------------------ | ------------------------------------------ | ------------------------------------------------------------------------- |
| `TILELANG_GIT_SHA` | *(none)* | tilelang commit to shallow-clone and compile (main mode). |
| `TILELANG_VERSION` | *(none)* | tilelang PyPI version to `pip install` (release mode). |
| `BASE_IMAGE` | `nvidia/cuda:12.9.1-devel-ubuntu22.04` | Public CUDA `devel` base (Python 3.12 via deadsnakes). |
| `MAX_JOBS` | `64` | Parallelism for the tilelang / FA2 / FA3 source builds. |
| `NVCC_THREADS` | `4` | Per-`nvcc` threads. |
| `DEEPGEMM_GIT_SHA` | `c9f8b34dcdacc20aa746b786f983492c51072870` | DeepGEMM commit for the grouped-GEMM benchmark baseline (`v2.1.1.post3`). |
| `RUNNER_VERSION` | `2.334.0` | GitHub Actions runner version baked into `final`. |
Set exactly one of `TILELANG_GIT_SHA` / `TILELANG_VERSION`; the build fails fast if neither is set.
### Stages (`--target`)
| Stage | Contents |
| ----------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `runtime` | Python 3.12 + torch / torchvision / torchaudio `2.10.0 / 0.25.0 / 2.10.0 +cu129` + triton `3.6.0` + tilelang build/runtime deps (incl. `apache-tvm-ffi 0.1.11`). **No tilelang itself.** |
| `post-fa3` | `runtime` + pytest / pytest-xdist / ruff + FlashAttention-3 (built from the `hopper/` source). |
| `fa2` | `post-fa3` + FlashAttention-2 (`flash-attn 2.8.3`, source-built in its own layer so changes to the bench loop never recompile it). |
| `fullstack` | `fa2` + flash-linear-attention `0.4.2` + vLLM `0.19.1` + mamba-ssm `2.3.1` + DeepGEMM `2.1.1.post3`, then flashinfer-python/-cubin upgraded to `0.6.11.post2` (`--no-deps`, so torch stays +cu129). sgl-kernel is not installed. |
| `tilelang` | `fullstack` + the tilelang wheel (`--no-deps`), then the build-time guard. Built **last** so a SHA bump rebuilds only this layer. |
| `final` | `tilelang` + the GitHub Actions runner (no TileOPs source baked). |
Build an earlier stage for debugging with `--target runtime` (etc.).
The `tilelang` stage ends by running `scripts/ci/verify_runtime_stack.py` (GPU-free): it fails
the build unless tilelang imports, the installed `apache-tvm-ffi` sits inside the tilelang
wheel's declared range, and torch is still the cu129 build.
## Verify the built image
```bash
docker run --rm --gpus all ghcr.io/tile-ai/tileops-runner:65dbc98 python - <<'PY'
import torch
print("torch", torch.__version__, "cuda", torch.version.cuda) # expect 2.10.0+cu129, cuda 12.9
import tilelang; print("tilelang", tilelang.__version__)
import flashinfer, flashinfer_cubin
print("flashinfer", flashinfer.__version__)
from pathlib import Path
cubin_dir = Path(flashinfer_cubin.get_cubin_dir())
probe_dir = cubin_dir / "flashinfer" / "trtllm" / "gemm" / "_tileops_write_probe"
probe_dir.mkdir(parents=True, exist_ok=True)
(probe_dir / "probe.txt").write_text("ok")
print("flashinfer cubin write OK")
import selective_scan_cuda
import mamba_ssm
from mamba_ssm.ops.triton.ssd_combined import mamba_chunk_scan_combined
assert mamba_chunk_scan_combined is not None
print("mamba", mamba_ssm.__version__)
import deep_gemm
print("deep_gemm", deep_gemm.__version__)
# cuBLAS probe: matmul / bmm / einsum on the GPU
a = torch.randn(512, 512, device="cuda", dtype=torch.float16)
b = torch.randn(512, 512, device="cuda", dtype=torch.float16)
assert torch.matmul(a, b).isfinite().all()
ab = torch.randn(8, 128, 128, device="cuda", dtype=torch.float16)
assert torch.bmm(ab, ab).isfinite().all()
assert torch.einsum("bik,bkj->bij", ab, ab).isfinite().all()
print("cuBLAS probe OK")
PY
```
Then run the smoke tests against a checkout of this repo:
```bash
docker run --rm --gpus all -v "$PWD:/src" -w /src \
ghcr.io/tile-ai/tileops-runner:65dbc98 \
bash -c 'scripts/ci/install_tileops.sh && pytest -m smoke'
```
`install_tileops.sh` installs TileOPs `--no-deps` against the baked stack; it fails fast if
tilelang is missing (the image provides it).
## Run as a self-hosted runner
`entrypoint.sh` registers an ephemeral runner (one job per container), then deregisters on
exit. Provide a registration token and the target URL; bind-mount the host cache. The
entrypoint removes `RUNNER_TOKEN` from the environment before the runner starts, so jobs
cannot read the registration token.
```bash
docker run -d --gpus all \
-e RUNNER_URL=https://github.com/tile-ai/TileOPs \
-e RUNNER_TOKEN=<registration-token> \
-e RUNNER_LABELS=self-hosted,tile-ops,venv \
-v <host-cache-dir>:/ci-cache \
ghcr.io/tile-ai/tileops-runner:65dbc98
```
The image sets cache env vars (`TILELANG_CACHE_DIR`, `TRITON_CACHE_DIR`, `PIP_CACHE_DIR`, …)
under `/ci-cache`; the directories are pre-created so the container also works unmounted.
## Bumping the tilelang commit
A commit (or release) bump always rebuilds, but **never edits the Dockerfile**: rebuild with a
new `--build-arg TILELANG_GIT_SHA=<commit>` (or `TILELANG_VERSION=<version>`) and a new
`:<short-sha>` tag, push to `ghcr.io`, then point the runner at the new tag. Because tilelang
is the last stage, only its layer recompiles — the bench layers (FA2 / FA3 / vLLM / …) stay
cached. Switching between a release and a main commit is the same — only the build-arg and tag
change.

# CLAUDE.md
## Project Overview
TileOPs is a high-performance LLM operator library built on TileLang. The goal is to provide efficient, modular, and maintainable AI workload implementations.
This project follows **design-first, spec-driven** development: design docs and `tileops/manifest/` are the authoritative spec; code conforms to the spec, not the other way around.
## Development Environment
Activate a virtual environment, then `make install` (deps + pre-commit hooks).
## Key References
### Design
- [architecture.md](docs/design/architecture.md) — system modules (M1-M8), data flow, agent production loop, directory structure
- [ops-design.md](docs/design/ops-design.md) — Op interface execution guide (how to add a new op)
- [ops-design-reference.md](docs/design/ops-design-reference.md) — Op interface detail reference (interface tables, codegen, naming, protocol)
- [manifest.md](docs/design/manifest.md) — `tileops/manifest/` spec format (signature, workloads, roofline, source)
- [roofline.md](docs/design/roofline.md) — `tileops/manifest/` `roofline` field spec: performance model, authoring, and per-consumer contracts (validator / benchmark / M5 / codegen)
### Process
- [trust-model.md](docs/design/trust-model.md) — trust boundaries (manifest → test → implementation → benchmark), workloads layer contract
- [testing.md](docs/design/testing.md) — test/benchmark framework, core abstractions, tolerances, reporting rules
- [tileops-skills.md](docs/tileops-skills.md) — developer decision guide: which repo-provided skill to use for which task
## Reading the ops manifest
The manifest lives at `tileops/manifest/`, one or more YAML files per op family — most families use a single file; large families may be sharded across multiple files. The `tileops.manifest` package merges them into a single `ops` dict at runtime.
- **Programmatic reads**: prefer `from tileops.manifest import load_manifest, load_workloads`. Never re-implement the merge.
- **Structural inspection**: parse the relevant family file with `yaml.safe_load` and index `ops` by op name. Pick the file from the op's family field rather than scanning all of them.
- **Edits**: edit the single family file that owns the op. Use a round-trip parser (`ruamel.yaml`) to preserve comments and key order. Op names must remain unique across files — duplicates raise at load time.
- Reserve `Read`/`grep` for targeted line lookups inside one family file, not structural reading.
## Domain Rules (load on demand)
Read the relevant context file **before** modifying files in that domain. Do not load them if your task does not touch that domain.
| When you modify | Read first |

## 2026 Summer Camp
Summer-camp participants should use the `summer-camp-2026` branch and follow the [Chinese migration guide](docs/summer-camp/README.md). The guide defines operator claiming, the two-PR Manifest/implementation workflow, MetaX GPU validation, benchmarking, Roofline evidence, and acceptance criteria; claimable projects are listed in the [operator migration inventory](docs/summer-camp/TileKernels-MACA-operator-migration-inventory.en.md).
We recommend renting online MetaX C500 compute through the [Gitee AI Compute Marketplace](https://ai.gitee.com/compute) and selecting the summer-camp image: `PyTorch-Agent / 2.8.0 / Python 3.12 / MACA 3.7.1.5`. See the [detailed English guide](docs/summer-camp/README.en.md) for setup and environment self-check requirements.
## Overview
TileOPs is a GPU operator library for LLM training and inference, built on [TileLang](https://github.com/tile-ai/tilelang). Beyond providing a growing collection of production-quality operators, TileOPs explores a **spec-driven development model** where AI agents can read declarative operator specifications, generate kernel implementations, and evaluate them against hardware-theoretical performance bounds — with minimal human scaffolding.
### Architecture
Every operator is split into two layers with a strict boundary:
- **Op** (L2) — stateless Python entry point. Handles validation, dtype casting, and memory layout. Compatible with CUDA-Graph and `torch.compile`.
- **Kernel** (L1) — TileLang GPU implementation with hardware-specific optimizations. Upstream TileOPs kernels declare their support range in NVIDIA architecture terms (Ampere, Hopper); this repository adds `*_maca.py` implementations for some operators, dispatched at the Op layer via `is_maca()`. See [Operator availability on MetaX C500](docs/summer-camp/README.en.md#12-operator-availability-on-metax-c500).
This separation keeps user-facing behavior independent of GPU strategy, allowing agents and developers to modify either layer without side effects on the other.
### Key Properties
- **Spec-driven** — each operator is declared in a machine-readable manifest (`tileops/manifest/`) that specifies signatures, workloads, and roofline formulas, serving as the entry point for both agent code generation and automated validation
- **Roofline-evaluated** — kernel performance is measured against Speed-of-Light hardware bounds, not relative baselines
- **Auto-tuning** — built-in search over tile sizes, pipelines, and scheduling parameters
- **Lightweight** — depends only on TileLang, PyTorch, and einops
## Installation
An MXMACA-capable MetaX GPU is required at runtime.
### Prerequisites
- Python >= 3.10
- PyTorch >= 2.1 (MetaX build, e.g. `2.8.0+metax3.7.1.3`)
- MetaX GPU: **C500**
- [TileLang](https://github.com/tile-ai/tilelang): on MetaX, use the pre-built MACA version shipped in the container
> [!WARNING]
> **Inside a MetaX container, do not run `make install`, `pip install tileops`, or any pip
> command that resolves the tilelang dependency.**
>
> The container's TileLang is an in-place source build for MACA (e.g.
> `/opt/tilelang-metax-v0.1.10`), not a pip package — `pip show tilelang` finds nothing.
> pip therefore treats it as "not installed" and pulls the official **CUDA** wheel from the
> index into site-packages, shadowing the MACA build so kernels compile for the wrong backend.
>
> For the same reason, do not use `python3 -m venv` without `--system-site-packages`: it cuts
> off the MetaX PyTorch build and the `apache-tvm-ffi` that `libtilelang.so` is ABI-coupled to.
>
> Do not pass `-c constraints.txt` either. Those pins target the CUDA CI runner and would
> downgrade `apache-tvm-ffi` below what the in-place build was compiled against. Such a
> mismatch is invisible at `import` time and only fails when the first kernel compiles.
### MetaX: use the container's pre-built TileLang
Nothing needs to be installed. Set `PYTHONPATH` and you are ready:
```bash
# Point at the container's pre-built MACA TileLang, plus this repository root
export PYTHONPATH=/opt/tilelang-metax-v0.1.10:/path/to/TileOPs-Metax:$PYTHONPATH
```
`tileops` imports without `pip install`; Manifest validation and tests run directly.
If you do need `tileops` registered in the environment (for example to run scripts from outside the repository), `--no-deps` is the only safe form:
```bash
python -m pip install -e . --no-deps --no-build-isolation
```
`--no-deps` is the essential part — it stops pip from resolving `tilelang`. The repository's CI uses exactly this form in [`scripts/ci/install_tileops.sh`](scripts/ci/install_tileops.sh).
Verify:
```bash
# MetaX GPU status. If the output has a Sliced GPU section, the usable memory and compute
# are the slice quota, not the whole-card values shown in the first section
mx-smi
python --version
python -c "import torch; print(f'GPU available: {torch.cuda.is_available()}')"
# PyTorch must be the MetaX build (version string contains 'metax')
python -c "import torch; print(f'PyTorch {torch.__version__}')"
# TileLang must come from the container's MACA build, not a pip-installed CUDA wheel.
# The path should be under /opt/tilelang-metax-*; site-packages means it was overwritten
python -c "import tilelang; print(tilelang.__version__); print(tilelang.__file__)"
# The compilation backend must be maca, not cuda
python -c "from tilelang.utils.target import determine_target; print(determine_target('auto'))"
python -c "import einops; print('einops OK')"
```
## Quick Start
```python
import torch
from tileops.ops import GemmOp
M, N, K = 1024, 1024, 512
# GemmOp is input-inferred: m/n/k and dtype come from the forward inputs, so the
# constructor only declares layout. trans_b=False means B is stored [K, N];
# the default True corresponds to [N, K].
gemm = GemmOp(trans_a=False, trans_b=False)
A = torch.randn(M, K, device="cuda", dtype=torch.float16)
B = torch.randn(K, N, device="cuda", dtype=torch.float16)
C = gemm(A, B) # [M, N]
```
> [!NOTE]
> Set `PYTHONPATH` first (see Installation above).
>
> On C500, `GemmOp` dispatches through `is_maca()` to
> `tileops/kernels/gemm_maca.py`. Not every operator has a MACA implementation — before
> picking an operator or a workload, read
> [Operator availability on MetaX C500](docs/summer-camp/README.en.md#12-operator-availability-on-metax-c500).

## 首届开源英才夏令营
夏令营学员应使用 `summer-camp-2026` 分支，并遵循[算子迁移指南](docs/summer-camp/README.zh-CN.md)。
### 任务说明
学员以小组为单位，从筹备组发布的[候选算子清单](docs/summer-camp/TileKernels-MACA-待迁移算子盘点.md)中选择一个主算子。候选算子主要来源于 [`MetaX-MACA/TileKernels-Metax`](https://github.com/MetaX-MACA/TileKernels-Metax) 的 `dev` 分支，并已初步评估 MetaX C500 适配或性能优化空间。学员需要按照 TileOPs 的接口和工程规范完成算子泛化、迁移或优化，而不是简单复制源实现：
1. 认领算子并提交 Manifest；
2. 完成 Op、TileLang Kernel、正确性及边界测试；
3. 在真实 MetaX C500 上完成正确性验证、Benchmark、Profiler 和 Roofline 分析；
4. 提交可 Review 的实现 PR，并参加成果答辩。
完整时间安排、提交要求和验收标准见[算子迁移指南](docs/summer-camp/README.zh-CN.md)。
**可认领范围以筹备组发布的候选算子清单为准，源仓库中的算子不会默认全部开放认领。每组应优先选择一个中等或较高难度的主算子；在保证主算子完整交付并经助教确认后，最多可追加两个算子。每个算子须单独认领并分别提交 PR，不得提前占用尚未开始的算子。**
### 结营证书
按要求完成任务并参加成果答辩的学员，可获得本届开源英才夏令营结营证书。
### 优秀项目评选
答辩结束后，评委将结合小组答辩、PR、代码与测试质量、MetaX C500 验证证据、性能分析及开源复用价值，综合考虑算子难度、实际完成情况、优化效果和工程贡献，评出以下三个奖项：
- **最佳性能优化（1 组）**：性能分析准确，优化方案合理，在代表性工作负载上取得稳定且可信的性能提升。
- **最佳工程实践（1 组）**：算子交付完整，代码结构清晰，测试覆盖充分，PR 和复现材料规范。
- **最佳开源贡献（1 组）**：成果具有较高的复用、扩展或推广价值，能够帮助后续算子开发、硬件适配和社区协作。
原则上每组最多获得一个主奖。评奖不以绝对加速比作为唯一依据，评委将结合算子基础难度、工作量、完成质量和证据可信度综合判断。
## 项目简介
TileOPs-Metax 是一个基于 [TileLang](https://github.com/tile-ai/tilelang)、面向大语言模型训练和推理的 GPU 算子库。项目采用规范驱动的开发模式，帮助开发者和 AI Agent 构建、评估和优化高性能算子。
### 主要特性

## 首届开源英才夏令营
夏令营学员应使用 `summer-camp-2026` 分支，并遵循[算子迁移指南](docs/summer-camp/README.md)。该指南规定了算子认领、Manifest/实现双 PR 流程、MetaX GPU 验证、Benchmark、Roofline 证据和验收要求；可认领课题见[候选算子清单](docs/summer-camp/TileKernels-MACA-待迁移算子盘点.md)。
推荐通过[模力方舟算力市场](https://ai.gitee.com/compute)租用在线 MetaX C500 算力，并选择夏令营专属镜像：`PyTorch-Agent / 2.8.0 / Python 3.12 / MACA 3.7.1.5`。具体使用方法和环境自检要求见[详细中文指南](docs/summer-camp/README.zh-CN.md)。
## 概述
TileOPs 是一个基于 [TileLang](https://github.com/tile-ai/tilelang)、面向大语言模型训练和推理的 GPU 算子库。除了持续提供可用于生产的算子，TileOPs 还探索一种**规范驱动的开发模式**：AI Agent 可以读取声明式算子规范、生成 Kernel 实现，并依据硬件理论性能上限进行评估，同时尽量减少人工脚手架。
### 架构
每个算子都严格分为两个层次：
- **Op**（L2）——无状态 Python 入口，负责参数校验、dtype 转换和内存布局，并兼容 CUDA Graph 与 `torch.compile`。
- **Kernel**（L1）——TileLang GPU 实现，包含针对具体硬件的优化策略。上游 TileOPs 的 Kernel 按 NVIDIA 架构（Ampere、Hopper）声明支持范围；本仓库为部分算子提供 `*_maca.py` 专用实现，由 Op 层通过 `is_maca()` 分派。参见 [MetaX C500 上的算子可用范围](docs/summer-camp/README.zh-CN.md#12-metax-c500-上的算子可用范围)。
这种分层使面向用户的行为与 GPU 策略相互独立，AI Agent 和开发者可以修改其中一层，而不对另一层产生意外影响。
### 主要特性
- **规范驱动**——每个算子都由机器可读的 Manifest（`tileops/manifest/`）声明，
其中定义签名、工作负载和 Roofline 公式，同时作为 AI Agent 生成代码与自动验证的入口。
- **Roofline 评估**——Kernel 性能依据硬件 Speed-of-Light 理论上限评估，而不是只与相对基线比较。
- **自动调优**——内置对 tile 大小、流水线和调度参数的搜索。
- **轻量依赖**——仅依赖 TileLang、PyTorch 和 einops。
## 安装
运行时需要支持 MXMACA 的 MetaX GPU。
### 前置条件
- Python >= 3.10
- PyTorch >= 2.1（MetaX 定制版，如 `2.8.0+metax3.7.1.3`）
- MetaX GPU：**C500**
- [TileLang](https://github.com/tile-ai/tilelang)：MetaX 环境使用容器内预编译的 MACA 版本
> [!WARNING]
> **MetaX 容器内不要执行 `make install`、`pip install tileops`，或任何会解析 tilelang 依赖的 pip 命令。**
>
> 容器里的 TileLang 是源码就地编译的 MACA 版本（例如 `/opt/tilelang-metax-v0.1.10`），
> 不是 pip 包（`pip show tilelang` 查不到）。因此 pip 会认为它「未安装」，从镜像源拉取
> 官方 **CUDA** 构建的 wheel 装进 site-packages，遮蔽 MACA 编译产物，导致 Kernel 编译走错后端。
>
> 同理，不要使用不带 `--system-site-packages` 的 `python3 -m venv`，否则会切断 MetaX 定制版
> PyTorch 和与 `libtilelang.so` ABI 耦合的 `apache-tvm-ffi`。
>
> 也不要在 pip 命令中带 `-c constraints.txt`：该文件的钉版面向 CUDA CI 环境，会降级
> `apache-tvm-ffi`，与容器内编译产物 ABI 不匹配。这类不匹配在 `import` 阶段看不出来，
> 要到第一次编译 Kernel 时才会失败。
### MetaX 环境：使用容器内预编译的 TileLang
不需要安装任何东西。设置 `PYTHONPATH` 后即可直接使用：
```bash
# 指向容器内预编译的 MACA 版 TileLang，以及本仓库根目录
export PYTHONPATH=/opt/tilelang-metax-v0.1.10:/path/to/TileOPs-Metax:$PYTHONPATH
```
`tileops` 无需 `pip install` 即可导入，Manifest 校验和测试都能直接运行。
如果确实需要把 `tileops` 注册进环境（例如想在仓库外的目录运行脚本），只能用 `--no-deps`：
```bash
python -m pip install -e . --no-deps --no-build-isolation
```
`--no-deps` 是关键，它让 pip 不去解析 `tilelang` 依赖。仓库 CI 使用的 [`scripts/ci/install_tileops.sh`](scripts/ci/install_tileops.sh) 就是这个写法。
验证安装：
```bash
# 检查沐曦 GPU 状态。注意：若输出含 Sliced GPU 段落，实际可用显存和算力是切片配额，
# 不是第一段显示的整卡值
mx-smi
# 检查 Python 版本
python --version
# 检查 PyTorch 是否能识别 GPU
python -c "import torch; print(f'GPU available: {torch.cuda.is_available()}'); print(f'GPU count: {torch.cuda.device_count()}')"
# 检查 PyTorch 是 MetaX 定制版（版本号应含 metax）
python -c "import torch; print(f'PyTorch {torch.__version__}')"
# 检查 TileLang 来自容器内的 MACA 构建，而不是 pip 装的官方 CUDA 版。
# 路径应指向 /opt/tilelang-metax-*；若指向 site-packages，说明已被覆盖，需要恢复
python -c "import tilelang; print(tilelang.__version__); print(tilelang.__file__)"
# 检查编译后端是 maca 而不是 cuda
python -c "from tilelang.utils.target import determine_target; print(determine_target('auto'))"
python -c "import einops; print('einops OK')"
```
## 快速开始
```python
import torch
from tileops.ops import GemmOp
M, N, K = 1024, 1024, 512
# GemmOp 是输入推断的：m/n/k 和 dtype 由 forward 的输入决定，构造时只声明布局。
# trans_b=False 表示 B 按 [K, N] 存储；默认值 True 对应 [N, K]。
gemm = GemmOp(trans_a=False, trans_b=False)
A = torch.randn(M, K, device="cuda", dtype=torch.float16)
B = torch.randn(K, N, device="cuda", dtype=torch.float16)
C = gemm(A, B) # [M, N]
```
> [!NOTE]
> 运行前需要先设置 `PYTHONPATH`（见上文安装小节）。
>
> 在 C500 上，`GemmOp` 通过 `is_maca()` 分派到 `tileops/kernels/gemm_maca.py`。
> 并非所有算子都有 MACA 实现，选择算子和工作负载前请先阅读
> [MetaX C500 上的算子可用范围](docs/summer-camp/README.zh-CN.md#12-metax-c500-上的算子可用范围)。

3. For each of *n_trials* trials, profile *n_repeat* iterations

L2 is flushed before every iteration. Input tensors are cloned

Uses CUPTI via torch.profiler for accurate kernel-only timing, with
direct Kineto C++ event iteration to avoid Python parsing overhead.

# Hardware Microbenchmarks
GPU hardware characterization benchmarks that produce calibration factors for `tileops/perf/profiles/`.
## Prerequisites
- NVIDIA GPU with CUDA toolkit (`nvcc` in PATH)
- TileOPs installed (`pip install -e .` from project root)
- Root/sudo access for clock locking (recommended)
## HBM Bandwidth
Measures peak HBM bandwidth using vectorized CUDA kernels (float4 load/store) with cudaEvent timing. The calibration factor is derived from the **STREAM Triad** kernel (`a[i] = b[i] + s*c[i]`, 2 reads + 1 write), the industry-standard pattern for roofline bandwidth calibration.
Triad's 2:1 read:write ratio is closer to real compute kernels than pure copy (1:1), which suffers worst-case HBM bus turnaround overhead. Copy, read-only, and write-only results are included as reference measurements.
### Lock GPU clocks (recommended)
GPU boost clocks fluctuate during benchmarks. Lock memory and SM clocks to their maximum for stable, reproducible results:
```bash
# Lock clocks (requires root/sudo)
sudo nvidia-smi -lgc $(nvidia-smi --query-gpu=clocks.max.sm --format=csv,noheader,nounits)
sudo nvidia-smi -lmc $(nvidia-smi --query-gpu=clocks.max.mem --format=csv,noheader,nounits)
```
After benchmarking, reset to default:
```bash
sudo nvidia-smi -rgc
sudo nvidia-smi -rmc
```
### Run
Run from project root:
```bash
python benchmarks/hardware/memory/hbm_bandwidth.py --profile h200 --arch sm_90
```
Options:
| Flag | Default | Description |
| ----------- | ------- | ----------------------------------------------------------------------- |
| `--profile` | `h200` | GPU profile name (reads theoretical peak from `tileops/perf/profiles/`) |
| `--arch` | `sm_90` | CUDA compute capability for nvcc |
| `--size-mb` | `2048` | Working set size in MB |
### Output
```
Measured peak (triad vec4): 4070.44 GB/s
Theoretical: 4800.0 GB/s
Calibration: 0.8480
Update tileops/perf/profiles/h200.yaml:
hbm.calibration: 0.8480
```
### Methodology
- **Calibration kernel:** STREAM Triad `a[i] = b[i] + s*c[i]` (2 reads + 1 write, `float4` vectorized)
- **Reference kernels:** Copy (1:1 read:write), Read-only, Write-only
- **Timing:** `cudaEvent` (GPU-side, no host overhead)
- **Warmup:** 100 iterations per config (ensures boost clocks stabilize)
- **Measurement:** 200 iterations × 5 runs, report best and median
- **Working set:** 2 GB default (>> L2 cache, ensures HBM is measured)
- **Calibration source:** best Triad bandwidth across block size sweep (128/256/512)
## Adding a new GPU profile
1. Create `tileops/perf/profiles/<gpu>.yaml` with theoretical specs from the datasheet
1. Lock GPU clocks (see above)
1. Run `python benchmarks/hardware/memory/hbm_bandwidth.py --profile <gpu> --arch <sm_XX>`
1. Update `<gpu>.yaml` with the measured calibration factor
1. Reset GPU clocks
