Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00050 | $0.00678 |
| Opus 5.5 | $0.00020 | $0.00271 |
| Sonnet 5.5 | $0.00010 | $0.00136 |
| Haiku 4.5 | $0.00005 | $0.00068 |
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 19d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Commit Message Generation
Generate clear, concise commit messages following the Conventional Commits specification.
Read the changes with git diff --cached (or git diff when nothing is staged), git status and git log for the repository's style, then output the message. Don't stage, format, commit or amend anything unless the user explicitly asks for it.
Do not mention the AI assistant in the commit message (eg., "Co-authored-by: AI Assistant"). Instead, focus on the changes made, their purpose, and any relevant context.
Format
<type>(<scope>): <subject>
[optional body]
[optional footer(s)]
Rules
- type: Required, lowercase —
feat,fix,docs,style,refactor,perf,test,chore,ci,build,revert - scope: Optional, lowercase, in parentheses — module/component name
- subject: Required, lowercase, imperative mood, no period, max 72 chars
- body: Optional, wrap at 72 chars, explain what and why (not how)
- footer: Optional —

Type Selection
| Question | Type |
|---|---|
| Adding functionality? | feat |
| Fixing a bug? | fix |
| Documentation only? | docs |
| Code cleanup/restructure? | refactor |
| Improving performance? | perf |
| Tests only? | test |
| CI/build/deps? | ci / build / chore |
Commit Principles
- Atomic commits — one logical change per commit
- Independently revertable — each commit meaningful on its own
- Squash noise — merge "fix typo" / "address review" before merging
- Never mix unrelated changes in one commit
Examples
feat(auth): add password reset functionality
fix(api): resolve null pointer in user endpoint
feat(api)!: change user endpoint response format
BREAKING CHANGE: The user endpoint now returns an object instead of an array.
feat(payment): integrate stripe payment gateway
- Add stripe SDK integration
- Implement payment processing flow
- Add webhook handlers for payment events
Closes #234
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 this-is-tobi/tools (5 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 678 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 2026-08-31.
