commit-message

A change reviewer and Conventional Commits message writer. Conventional Commits are a standard format such as `fix: handle empty input` that tools can use to determine release versions.

In plain words
What is it for?
It helps inspect staged and unstaged Git changes, suggest one or more commit messages, explain the reason for the change, and state the implied semantic-release version bump.
Why use it?
It turns the actual working-tree changes into a clear commit message and highlights changes that can affect versioning or defensive code.

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 yesterday.

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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit Message

HARD GATEHARD GATE — Commits must follow Conventional Commits spec (type(scope): description). Do NOT use vague messages like 'fix' or 'updates.' The message must explain the 'why,' not the 'what.'

Modes

  • Default: standard Conventional Commits message
  • --fix-type: Forces type=fix. Use when commit type is unambiguous.

What "last chat" means

  • Primary source of truth: git status, git diff (unstaged), and git diff --cached (staged). Run these in the repo root (or the paths the user changed).
  • Context: use the current conversation to summarize intent and to spot breaking API/behavior changes that diff alone may not show.
  • If the user tracks a session baseline (e.g. branch, tag, or git stash create at start), you may git diff <baseline>..HEAD plus uncommitted diffs; otherwise use only the index and working tree.

Quick workflow

  1. Inventory — List changed paths; group by feature vs chore vs docs vs test-only.
  2. Decide commit shape — One atomic commit is ideal. If the diff mixes unrelated concerns, recommend multiple commits (each with its own type/scope) before suggesting one message.
  3. Classify for semantic releasefix → patch, feat → minor, breaking → major.
  4. Write the messagetype(optional-scope)!: description (see REFERENCE.md). Use ! or a BREAKING CHANGE: footer when behavior contracts change.
  5. Note defensive-code categories touched — from CONVENTIONS.md: Rate limit | Retry with backoff | Circuit breaker | Timeout | Graceful degradation
  6. Note fix-ratio contribution — Each fix: commit counts toward metrics.commit_ratio.fix in specs/state.yaml. After release-branch, session-state recalculates the ratio automatically. A high fix rate (>30%) triggers a deploy + smoke-test suggestion.
  7. Deliver — Output:
    • Proposed full commit message (title + optional body + footers).
    • Release bump this commit would drive: patch | minor | major | none.
    • Optional git add … and git commit -m instructions; do not run destructive git commands unless the user asked.

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.

commit-message is a skill published in the GitHub repository danielvm-git/bigpowers (156 stars, last pushed 25d ago), licensed MIT. It adds 71 tokens to every session and 1,933 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
