commit-message

commit-message is a skill for Claude Code, Codex from byerlikaya/claude-starter-kit. It costs 40 tokens per session (1,012 once invoked), scanned A, original, MIT.

A guide for writing Git commit messages in the Conventional Commits format, such as `fix(api): handle expired sessions`. It reads the staged changes and describes one logical change per commit.

In plain words
What is it for?
Use it to propose a commit type, optional scope, summary, body, and footer from the changes currently staged in Git.
Why use it?
Consistent messages make a project’s history easier to understand and help distinguish features, fixes, documentation, tests, and maintenance.

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

commit-message 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit Message (Conventional Commits v1.0.0)

Trigger phrases: "commit message", "make a commit", "conventional commit", "write a commit", "git commit"

Format: type(scope): summary + (optional blank line + body) + (optional footer).

Type (required)

  • feat — new feature · fix — bug fix
  • docs — docs only · refactor — restructure with no behavior change
  • perf — performance · test — add/fix tests
  • build — build/dependency · ci — CI configuration
  • chore — maintenance/automated · revert — revert a previous commit
  • style — formatting (no logic)

Which type? (deciding when ambiguous)

  • A new capability for the user? → feat. Fixing an existing wrong behavior? → fix.
  • Behavior the same, only the structure changed? → refactor (if behavior changed it's feat/fix, not refactor).
  • Touched only tests/docs/formatting? → test/docs/style (don't touch code logic).

Scope (optional, preferred)

The affected area/module: auth, api, backend, db, frontend, session, agent, etc. One word, consistent with the project's module name.

Summary line

  • In the project's established language (English by default for open source), imperative/summary mood, start lowercase, NO period at the end, ≤ ~72 characters.
  • Say what it does, not how; avoid vague words ("fix", "update", "wip"). ✅ feat(auth): one-time code TTL + brute-force limitfix: bug · ❌ update · ❌ changes

After a blank line: the WHY (motivation) + notable consequences/tradeoffs. Wrap at ~72 characters. Leave context for the future reader who opens git-blame — the diff already shows the "what"; you write the "why".

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
