Genshijin Commit (ultra-compressed commit messages)

Generates Conventional Commits messages with ≤50-character subjects that explain the "why" instead of restating the diff.

Dev & CodingBeginner★ 331⑂ 14AI score 10/10Last updated: Aug 15, 2026

What it does

  • Reads your staged diff and drafts a <type>(<scope>): summary message in Conventional Commits form.
  • Enforces hard limits: 50-char subject target (72 max), imperative mood, no trailing period.
  • Bans filler: emoji, "this commit will…", first-person phrasing, and any AI attribution footer.
  • Requires a body for breaking changes, security fixes, data migrations and reverts, plus trailers like BREAKING CHANGE: and Closes #42.
  • Matches the repo's existing commit language (Japanese/English) by checking git log.

Who it's for

  • Developers standardizing team commit history on Conventional Commits.
  • Projects relying on semantic-release or auto-generated changelogs.
  • Anyone who wants terse commits that still preserve context for future debuggers.

Examples

  1. After adding a profile endpoint, ask for a commit message → feat(api): add GET /users/:id/profile with a body explaining the bandwidth motivation.
  2. Renaming a public route → feat(api)!: ... subject plus a BREAKING CHANGE: migration deadline body.
  3. Tiny bug fix → a single line, no body: fix(auth): correct token expiry boundary check.

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/InterfaceX-co-jp/genshijin/HEAD/skills/genshijin-commit/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/genshijin-commit folder from the GitHub repo InterfaceX-co-jp/genshijin into my ~/.claude/skills/genshijin-commit/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/InterfaceX-co-jp/genshijin.git && mkdir -p ~/.claude/skills && cp -r genshijin/skills/genshijin-commit ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/InterfaceX-co-jp/genshijin.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r genshijin/skills/genshijin-commit ~/.claude/skills/
  5. Restart Claude Code, git add your changes, then ask "write a commit message".
  6. Paste the returned code block into git commit — the skill never stages or commits for you.
  7. Say "normal mode" to turn the compressed style off.
