+description:
+  "基于 staged diff 生成符合 commit_message.md 的提交信息建议（:emoji:
+  type(scope): subject）。Triggers: commit message, 提交信息, 写提交说明,
+  生成提交信息, emoji commit, git commit."
+---
+
+# Commit Message（提交信息建议器）
+
+目标：基于 `git diff --cached`（staged
+diff）生成 1–3 条提交信息建议：`:emoji: type(scope): subject`（可选 body/footer）。
+
+权威规范（单一真源，优先就近路径）：
+
+- `docs/common/commit_message.md`
+- `docs/standards/playbook/docs/common/commit_message.md`（Playbook
+  vendoring 场景）
+
+## When to use
+
+- 用户要“写提交信息 / 生成 commit message / 按规范写提交说明 / emoji commit”
+- 已经 `git add` 了一批改动，准备 `git commit`
+
+## Procedure（default）
+
+1. **收集 staged 概览（尽量小上下文）**
+   - `git diff --cached --name-status`
+   - `git diff --cached --stat`
+   - 必要时只看关键文件：`git diff --cached -- <path>`
+
+2. **读取并遵循权威规范**
+   - 优先读取就近的
+     `commit_message.md`（见上方路径），以其中的 type/emoji/格式为准。
+
+3. **生成 1 条主建议 + 2 条备选**
+   - 格式固定：`:emoji: type(scope): subject`（scope 可省略）。
+   - subject 用一句话描述“做了什么”，避免含糊词；尽量 ≤ 72 字符，不加句号。
+
+4. **判断是否建议拆分提交**
+   - 当 staged 同时包含多个不相关模块/目的时：建议拆分，并给出拆分方式（按目录/功能点/风险）。
+
+5. **可选：补充 body/footer（如需要）**
+   - body：说明 why/impact/verify（按规范建议换行）。
+   - footer：任务号或 `BREAKING CHANGE:`（若有）。
+
+6. **只给建议，不默认执行 `git commit`**
+   - 仅当用户明确要求时，才根据选定方案生成最终提交信息。
+
+## Output contract（固定输出）
+
+- Detected: staged files summary（文件数 + 关键路径 + 是否可能需要拆分）
+- Proposed:
+  - Option A（recommended）：`:emoji: type(scope): subject`
+  - Option B：...
+  - Option C：...
+- Optional body/footer（如适用）
+- Notes：规范路径命中情况（哪个 `commit_message.md` 被使用）
