+# 科研项目复现性审计（repro-audit）
+
+把 [`gitlink-repro-audit` Skill](../../../skills/gitlink-repro-audit/SKILL.md) 包成**可直接运行的科研辅助工具**（子赛题四：应用 GitLink 辅助科研）：
+
+> **采集 → 评估 → 报告 → 回写**：用 `repo +tree` / `file +view --raw` / `release +list` 采集仓库结构、README 与发布信息，做八维**确定性复现性检查**（文档 / 许可证 / 引用 / 依赖固化 / 运行入口 / 数据说明 / 测试 / 版本固化），输出 0-100 评分卡 + A/B/C/D 等级 + 逐项修复建议，并（仅在 `--apply` 时）用 `issue +create` 把报告作为改进 tracking issue 回写。
+
+## 科研赋能价值
+
+- **课题组自查**：论文投稿/开源发布前对代码仓库做复现性体检，逐项补齐
+- **学术规范检查**：许可证、引用信息（CITATION.cff/BibTeX）、数据可得性一次性核验
+- **可进 CI**：退出码 `2` 表示存在明显复现缺口，可作为科研仓库的发布门禁
+
+## 交付物
+
+- `scripts/repro_audit.py`：完整审计闭环（纯标准库，Python ≥3.9，零第三方依赖）
+- `tests/test_audit.py`：确定性回归护栏（7/7 全绿，同输入同分同等级）
+- `docs/verification.md`：真实科研仓库验证证据
+- `examples/demo-outputs/`：两个真实仓库的审计报告
+
+## 快速运行（默认 dry-run，不写远端）
+
+```bash
+npm install -g @gitlink-ai/cli
+gitlink-cli auth login
+
+python3 scripts/repro_audit.py --owner <owner> --repo <repo> --output-dir outputs
+# 回写改进 tracking issue（请先确认报告内容）：加 --apply
+```
+
+## 已在真实科研仓库验证
+
+见 [`docs/verification.md`](docs/verification.md)：
+
+| 仓库 | 类型 | 得分 | 等级 |
+|------|------|------|------|
+| GengzhaoWang/UAV-Paper | 论文笔记仓库 | 8/100 | D（复现困难，符合预期） |
+| momomym/paper-summarizer | 科研工具代码仓库 | 58/100 | C（缺引用/数据说明/release，建议明确） |
+
+两个仓库得分区分度显著，逐项证据均可在仓库页面人工复核。
+
+## 评分标准
+
+| 检查项 | 分值 | 判据 |
+|--------|------|------|
+| README 与运行说明 | 15 | README 存在且含运行/复现章节（仅 README 得 8） |
+| 开源许可证 | 15 | LICENSE / COPYING |
+| 引用信息 | 10 | CITATION.cff 或 README BibTeX |
+| 依赖清单 | 15 | requirements.txt / environment.yml / go.mod 等 |
+| 运行入口 | 10 | Makefile / run.sh / main.py / Dockerfile / scripts |
+| 数据可得性说明 | 10 | data 目录或 README 数据说明 |
+| 测试/验证代码 | 10 | tests 目录 |
+| 版本发布 | 15 | ≥1 个 release |
+
+等级：≥85 A / ≥70 B / ≥50 C / <50 D。
+
+> 依赖 `file` 快捷命令组（PR #330）；在其合并前可用 `--cli` 指向包含该命令的本地构建。

+## 1. 论文笔记仓库（预期低分）

+- 完整报告：[`../examples/demo-outputs/repro-audit-GengzhaoWang-UAV-Paper.md`](../examples/demo-outputs/repro-audit-GengzhaoWang-UAV-Paper.md)
+
+## 2. 科研工具代码仓库（中等分，建议明确）

+```bash

+```
+
+- 结果：**58/100 — C（存在明显缺口）**，退出码 `2`
+- 检出：LICENSE ✅、requirements.txt ✅、scripts 入口 ✅、tests ✅
+- 缺口：README 无运行章节（部分分 8/15）、无引用信息、无数据说明、无 release

+**CRITICAL — 开始前必须先阅读 [`../gitlink-shared/SKILL.md`](../gitlink-shared/SKILL.md)，其中包含认证、权限处理和 API 注意事项。**
+**CRITICAL — 审计本身只读；`--apply` 回写 tracking issue 前必须先向用户展示报告并确认。**
+**CRITICAL — GitLink 操作只能用 `gitlink-cli`。**

+## 功能概述
+
+论文代码「跑不起来」是科研复现危机的核心。本技能对科研代码仓库做系统化复现性评估：
+
+| 检查项 | 分值 | 判据 |
+|--------|------|------|
+| README 与运行说明 | 15 | 存在 README 且含 How to run / 复现步骤章节（仅有 README 得 8 分） |
+| 开源许可证 | 15 | LICENSE / COPYING 文件 |
+| 引用信息 | 10 | CITATION.cff 或 README 中的 BibTeX/引用章节 |
+| 依赖清单（环境固化） | 15 | requirements.txt / environment.yml / go.mod / package.json 等 |
+| 运行入口 | 10 | Makefile / run.sh / main.py / Dockerfile / scripts 目录 |
+| 数据可得性说明 | 10 | data 目录或 README 中的数据集来源说明 |
+| 测试/验证代码 | 10 | tests 目录 |
+| 版本发布（成果固化） | 15 | 至少一个 release |
+
+总分映射等级：≥85 A（可复现性良好）/ ≥70 B / ≥50 C / <50 D（复现困难）。
+
+## 使用方式
+
+### 方式一：确定性脚本（推荐，可进 CI）
+
+```bash
+python3 examples/research/repro-audit/scripts/repro_audit.py \
+  --owner <owner> --repo <repo> [--ref <branch>] [--apply]
+```
+
+- 默认 dry-run 只输出报告；`--apply` 用 `issue +create` 回写改进 tracking issue
+- 退出码：`0` 总分 ≥70（基本可复现），`2` 存在明显缺口
+
+### 方式二：AI Agent 手工执行命令链
+
+```bash
+# 1. 结构采集
+gitlink-cli repo +tree --owner <owner> --repo <repo> --format json
+# 2. README 内容
+gitlink-cli file +view --owner <owner> --repo <repo> --path README.md --raw
+# 3. 版本发布
+gitlink-cli release +list --owner <owner> --repo <repo> --format json
+# 4.（确认后）回写改进 issue
+gitlink-cli issue +create --owner <owner> --repo <repo> -t "[repro-audit] 复现性审计报告" -b "<报告>"
+```
+
+AI 按上表逐项打分，报告须给出每项证据与修复建议，不允许笼统结论。
+
+## 注意事项
+
+- 判据基于仓库顶层结构与 README 文本，属于必要条件检查：高分不代表结果一定可复现，低分则一定存在工程缺口。
+- 对论文笔记类仓库（纯 Markdown）等级普遍偏低，属预期行为；报告建议仅在其确为「实验代码仓库」时回写。
+- 与 [`../gitlink-doc-sync/SKILL.md`](../gitlink-doc-sync/SKILL.md)（文档一致性）、[`../gitlink-license-compliance/SKILL.md`](../gitlink-license-compliance/SKILL.md)（许可证合规）互补：本技能聚焦复现性维度的整体评估。
