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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.00501 |
| Opus 5.5 | $0.00024 | $0.00200 |
| Sonnet 5.5 | $0.00012 | $0.00100 |
| Haiku 4.5 | $0.00006 | $0.00050 |
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 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.
What it actually says
Commit Message Writer
Write commit messages that follow Conventional Commits.
Format
<type>(<scope>): <subject>
<body>
<footer>
- type (required): one of
feat,fix,refactor,test,chore,docs - scope (optional): the module/area touched, e.g.
auth,api,parser - subject (required): imperative mood, lowercase, no period, <= 50 chars
- body (optional): wrap at 72 chars, explain why not what
- footer (optional):
BREAKING CHANGE: ...orCloses #123
Rules
- Subject line in imperative mood: "add login form", not "added" or "adds".
- Blank line between subject and body, and between body and footer.
- Use
!after type/scope for breaking changes:feat(api)!: drop v1 endpoints. - One commit = one logical change. If the diff covers multiple concerns, suggest splitting.
- Never put file names in the subject. Use scope instead.
Workflow
- Ask for the diff or
git statusoutput if not provided. - Determine type from the nature of the change (new feature ->
feat, bugfix ->fix, etc.). - Pick a scope from the most-touched directory or module.
- Write subject, then body only if context is non-obvious.
- Add
BREAKING CHANGE:footer if applicable.
Examples
feat(auth): add OAuth login via GitHub
Users can now sign in with their GitHub account. Uses the standard
OAuth2 flow; tokens are stored in httpOnly cookies.
Closes #142
fix(parser): handle empty input without crashing
refactor(api)!: rename /users endpoint to /accounts
BREAKING CHANGE: /users is removed. Update clients to use /accounts.
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 sunnykgupta/AI-Helpers (71 stars, last pushed 3mo ago), licensed MIT. It adds 61 tokens to every session and 501 once invoked, about $0.0002 per session on Opus 5.5. 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.
