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

tldr-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 1mo 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

86% identical to caveman-commit — 13 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.

What it actually says

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
  • 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 tldr-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.
