A reference for commitlint, a tool that checks whether Git commit messages follow defined rules. It also describes how to find relevant guidance and map tasks to categories.

Use it to define or check commit-message conventions and to locate guidance for commit-related tasks.

It helps teams keep commit history consistent and catch incorrectly formatted messages before they enter the project history. Consistent messages make changes easier to review and organize.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00065	$0.01055
Opus 5	$0.00032	$0.00528
Sonnet 5	$0.00013	$0.00211
Haiku 4.5	$0.00006	$0.00105

Security

Grade A, and why

commitlint 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 9d 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.

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.
