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 | $0.00028 | $0.00299 |
| Opus 5.5 | $0.00011 | $0.00120 |
| Sonnet 5.5 | $0.00006 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
commit-helper 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 Helper
Generate well-structured commit messages following conventional commit format.
Instructions
- Run
git diff --stagedto see staged changes - Analyze the changes to understand:
- What files were modified
- What type of change (feat, fix, refactor, docs, etc.)
- The scope/component affected
- Generate a commit message with:
- Summary line under 50 characters
- Type prefix (feat, fix, docs, refactor, test, chore)
- Optional scope in parentheses
- Detailed body explaining what and why
Commit Types
feat: New featurefix: Bug fixdocs: Documentation changesrefactor: Code restructuring without behavior changetest: Adding or updating testschore: Maintenance tasks
Best Practices
- Use present tense ("Add feature" not "Added feature")
- Explain what and why, not how
- Keep summary concise but descriptive
- Reference issue numbers when applicable
Example Output
feat(auth): add OAuth2 support for GitHub login
- Implement OAuth2 flow with PKCE
- Add token refresh mechanism
- Store tokens securely in encrypted storage
Closes #123
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-helper is a skill published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 6mo ago), licensed MIT. It adds 28 tokens to every session and 299 once invoked, about $0.0001 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.
