commit-helper

A commit-message helper for Git, the version-control system used to record code changes. It turns a change description into a Conventional Commit subject line, a standard format such as "fix: correct login error".

In plain words
What is it for?
Use it when you need a short, correctly formatted commit subject for a new feature, bug fix, documentation change, refactor, test, or maintenance task.
Why use it?
It removes the need to remember the required commit-message format and wording rules.

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.

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

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 yesterday.

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

When the user describes a change they made, produce a Conventional Commits subject line for it.

Call the format_commit tool with:

  • type — one of feat, fix, docs, refactor, test, chore
  • scope — optional; the package or area that changed
  • summary — a short, imperative one-line description

Return the tool's output verbatim as the commit subject. Do not hand-format the subject yourself; the tool owns the formatting rules.

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.
