What it does
Commit Message is an agent skill from revfactory/harness-engineering-with-cc. 스테이지된 변경을 바탕으로 Conventional Commits 형식의 커밋 메시지를 2인 팀(author·reviewer)으로 생성. '커밋 메시지', 'commit message', '커밋 메시지 만들어줘' 같은 자연어 요청 시 반드시 사용. 단, 이미 메시지가 작성된 git commit -m 대체는 아니다.
Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Commit messages. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Commit messages
Example prompts
- “commit message”
- “/commit-message”
Requirements
- Pre-approved tools (allowed-tools): Bash, Read, Write
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Precondition 체크.
- author 호출.
- reviewer 호출.
- 판정 분기.
- 루프 종료.
What it can do on your machine
Read from SKILL.md and the folder at commit d81b72b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Commit Message loads about 222 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 101 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Write
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
The full file from revfactory/harness-engineering-with-cc at commit d81b72b, republished under its Apache-2.0 licence (© revfactory). 101 words, ~222 tokens.

Commit Message Skill
2인 팀을 순차로 호출해 Conventional Commits 형식의 커밋 메시지를 생성한다.
Workflow
- Precondition 체크.
git diff --cached --quiet를 실행한다. exit code 1(변경 있음)이면 통과, exit code 0(변경 없음)이면 "먼저git add" 안내 후 종료. - author 호출.
commit-msg-author에이전트를 Agent 도구로 호출. 출력은_workspace/commit-draft.md. - reviewer 호출.
commit-msg-reviewer에이전트를 Agent 도구로 호출. 출력은_workspace/review-report.md. - 판정 분기.
- PASS.
_workspace/commit-draft.md내용을 사용자에게 제시하고 완료. - REDO. reviewer 수정 지시를 프롬프트에 포함해 author 재호출 (최대 2회).
- PASS.
- 루프 종료. PASS 또는 재호출 2회 초과 시 종료. 초과 시 "자동 승인 한계 도달 — 수동 검토 권장" 경고와 함께 마지막 draft 반환.

When should I use Commit Message?
Commit Message fits situations like: tasks that involve Commit messages.
How do I install Commit Message in Claude Code?
Run `npx skills add revfactory/harness-engineering-with-cc --skill commit-message -a claude-code`. Or copy the skill folder (ex-02-02-my-first-harness/.claude/skills/commit-message in revfactory/harness-engineering-with-cc) into .claude/skills/commit-message in your project. Claude Code loads it when a task matches its description.
How do I install Commit Message in Codex?
Run `npx skills add revfactory/harness-engineering-with-cc --skill commit-message -a codex`. Or copy the skill folder (ex-02-02-my-first-harness/.claude/skills/commit-message in revfactory/harness-engineering-with-cc) into .agents/skills/commit-message in your project. Codex loads it when a task matches its description.
Can I use Commit Message in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add revfactory/harness-engineering-with-cc --skill commit-message -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/commit-message, .gemini/skills/commit-message, .github/skills/commit-message and .opencode/skills/commit-message in your project.
What does Commit Message need to run?
Going by SKILL.md and its folder, Commit Message needs the command-line tools its instructions call (git). Its frontmatter pre-approves these tools: Bash, Read, Write.
Does Commit Message access the network?
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Commit Message safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Commit Message use?
Commit Message is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Commit Message use?
About 222 tokens (SKILL.md is roughly 888 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Commit Message?
Skills that share tags, products or a category with Commit Message: Contextual Commit Messages (yamadashy/repomix, 29k stars), React Router Release Notes Prep (remix-run/react-router, 57k stars), PR Finalize Review (microsoft/garnet, 12k stars) and Caveman Commit (vishiri/fantasia-archive, 409 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
