Changelog 自动生成

触发条件

当用户要求生成 changelog、更新日志、版本记录、release notes 时激活此技能。

工作流程

第 1 步：获取 Git 历史

# 先获取最近的 tag，再用 revision range 查询
git describe --tags --abbrev=0
git log --oneline <last-tag>..HEAD

# 或指定范围
git log --oneline v1.0.0..HEAD

# 仓库没有 tag 时，明确选择起始提交或查看全部历史
git log --oneline

第 2 步：分类提交

按 Conventional Commits 分类：

| 分类 | Type 标识 | 图标 |

|------|----------|------|

| 新功能 | feat | ✨ |

| Bug 修复 | fix | 🐛 |

| 文档 | docs | 📝 |

| 重构 | refactor | ♻️ |

| 性能优化 | perf | ⚡ |

| 测试 | test | 🧪 |

| 构建/工具 | chore | 🔧 |

| Breaking Changes | 含 BREAKING CHANGE: 或 ! | ⚠️ |

| 安全修复 | fix(security) 或含 CVE | 🔒 |

| 依赖更新 | deps 或 chore(deps) | 📦 |

第 3 步：版本号确定策略

遵循 Semantic Versioning 规则：

| 变更类型 | 版本变化 | 示例 |

|---------|---------|------|

| Breaking Changes | 主版本 +1 | 1.2.0 → 2.0.0 |

| 新功能 (feat) | 次版本 +1 | 1.2.0 → 1.3.0 |

| Bug 修复 (fix) | 修订版本 +1 | 1.2.0 → 1.2.1 |

| 安全修复 (fix(security)) | 修订版本 +1（紧急发布） | 1.2.0 → 1.2.1 |

判断依据：

提交信息含 BREAKING CHANGE: 或 type 后加 !（如 feat!:）→ 主版本
存在 feat 提交 → 次版本
仅 fix/docs/chore 等 → 修订版本

第 4 步：生成 CHANGELOG

输出格式

# Changelog

注意事项

Breaking Changes 必须放在最前面，加粗突出显示
每条记录关联 Issue/PR 编号，便于追溯
安全修复需注明 CVE 编号（如有）
版本号应与 git tag 保持一致
如果是预发布版本，使用 -beta.1、-rc.1 后缀
可维护一个 CHANGELOG.md 文件，每次 release 追加到顶部
