Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

changelog-gen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
