caveman-commit

caveman-commit is a skill for Claude Code, Codex from RainMT-dv/skills-pack. It costs 79 tokens per session (654 once invoked), scanned A, a copy of caveman-commit, MIT.

A commit-message writer that produces short messages in Conventional Commits format, a common structure used to describe software changes.

In plain words
What is it for?
Use it when creating commit messages, especially when you need the right change type, a concise subject, or a brief explanation of a non-obvious change.
Why use it?
It removes filler and keeps the message focused on the change and, when needed, the reason behind it.

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

caveman-commit 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 3d 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.

Origin

This is a copy

89% identical to caveman-commit — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Write commit messages terse and exact. Conventional Commits format. No fluff. Why over what.

Rules

Subject line:

  • <type>(<scope>): <imperative summary><scope> optional
  • Types: feat, fix, refactor, perf, docs, test, chore, build, ci, style, revert
  • Imperative mood: "add", "fix", "remove" — not "added", "adds", "adding"
  • ≤50 chars when possible, hard cap 72
  • No trailing period
  • Match project convention for capitalization after the colon

Body (only if needed):

  • Skip entirely when subject is self-explanatory
  • Add body only for: non-obvious why, breaking changes, migration notes, linked issues
  • Wrap at 72 chars
  • Bullets - not *
  • Reference issues/PRs at end: Closes #42, Refs #17

What NEVER goes in:

  • "This commit does X", "I", "we", "now", "currently" — the diff says what
  • "As requested by..." — use Co-authored-by trailer
  • "Generated with Claude Code" or any AI attribution — unless the user's own rule requires an Assisted-by/AI-attribution trailer, then add it as a trailer
  • Emoji (unless project convention requires)
  • Restating the file name when scope already says it

Examples

Diff: new endpoint for user profile with body explaining the why

  • ❌ "feat: add a new endpoint to get user profile information from the database"
  • feat(api): add GET /users/:id/profile
    
    Mobile client needs profile data without the full user payload
    to reduce LTE bandwidth on cold-launch screens.
    
    Closes #128
    

Diff: breaking API change

  • feat(api)!: rename /v1/orders to /v1/checkout
    
    BREAKING CHANGE: clients on /v1/orders must migrate to /v1/checkout
    before 2026-06-01. Old route returns 410 after that date.
    

Auto-Clarity

Always include body for: breaking changes, security fixes, data migrations, anything reverting a prior commit. Never compress these into subject-only — future debuggers need the context.

Boundaries

Only generates the commit message. Does not run git commit, does not stage files, does not amend. Output the message as a code block ready to paste. "stop caveman-commit" or "normal mode": revert to verbose commit style.

Files

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.
