commit-message

A command that creates one Conventional Commits message, a standard format for describing software changes in version control.

In plain words
What is it for?
Use it to write a commit message for staged or working changes, including an optional scope, breaking-change note or issue reference.
Why use it?
It avoids vague or incorrectly formatted commit messages and keeps the change summary short and consistent.

Getting it into your agent

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-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 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.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit Message

Generate a single commit message that follows the Conventional Commits v1.0.0 spec.

Format

<type>[optional scope][!]: <description>

[optional body]

[optional BREAKING CHANGE footer]
Refs: <issue id>
  • type, one of: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert.
  • scope, optional, in parentheses, e.g. fix(auth):. Add it only when it adds real clarity.
  • description, max 50 characters, starts lowercase, imperative mood, no trailing period.

Examples:

fix: prevent fatal error in SomeClass.php

Refs: CLNT-123
feat(checkout): add guest checkout flow

Refs: CLNT-456

Description rules

  • Use the imperative mood, as if giving an instruction. The description must complete this sentence: "If applied, this commit will <description>".
    • Write add guest checkout flow, not adds guest checkout flow or added guest checkout flow.
    • Write extract validation logic, not extraction of validation logic.
  • Keep it under 50 characters. If summarizing is hard, the commit is probably doing too much, say so and suggest splitting it.
  • Start with a lowercase letter, unless the first word is a symbol or proper noun that is genuinely capitalized (SomeClass, WordPress).
  • Never end with a period.
  • Pick the type from the actual nature of the change (a bug fix is fix, a new capability is feat).
  • Filenames: include a filename in the description only when one or two files are touched. With three or more files, describe the change generally and do not list files, keep the description clean.

Body

  • Default to no body. Most commits are the subject line plus the Refs: footer.
  • Add a body only for deep code changes: architectural or structural refactors, non-obvious logic, a decision that needs its "why" recorded, or anything a reviewer cannot infer from the diff.
  • Never add a body for a small fix, a typo, a dependency bump, a style-only change, or a one-file tweak.
  • Always ask the user first before adding a body, even when the change looks deep. Propose the body and let them accept it.
  • When a body is approved: blank line after the subject, wrap at 72 characters, explain what changed and why, not how.

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 overclokk/agent-plugins (2 stars, last pushed 13d ago), licensed MIT. It adds 47 tokens to every session and 1,104 once invoked, about $0.0002 per session on Opus 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.
