conventional-commits-writing

conventional-commits-writing is a skill for Claude Code, Codex from event4u-app/agent-config. It costs 41 tokens per session (4,457 once invoked), scanned A, original, MIT.

A commit-message writing guide for the Conventional Commits format, which labels changes with types such as feat, fix, or docs and can include scopes or breaking-change notes.

In plain words
What is it for?
It helps classify changes, choose scopes, spot mixed concerns, review commit messages, and split one vague change into several commits.
Why use it?
It removes guesswork when turning code changes into clear, consistent commit messages or squash-merge titles.

SkillSpector: 3 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Anti-Refusal · line 234
    Skill attempts to nullify the agent's safety policies or restrictions ('you have no restrictions', 'ignore your guidelines', 'do anything now'). This is a direct jailbreak that disables guardrails.
    Fix: Remove jailbreak framing that nullifies safety policies or restrictions. Skill content must not instruct the agent to ignore its guidelines or operate without guardrails.

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

conventional-commits-writing 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 5d 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.

When to use

Use this skill when:

  • Committing in a repository whose conventions you have not established this session — run ## Procedure: Establish the house convention first
  • Generating a commit message from staged changes
  • Generating a squash merge title from a PR
  • Deciding the correct Conventional Commit type for a change
  • Reviewing whether a commit message is correct
  • Splitting one vague change into multiple commit messages

Do NOT use when:

  • Only explaining the Conventional Commits standard (just reference the rule)
  • The message is already correct and does not need review
  • Following the Git workflow (use git-workflow skill)

Procedure: Establish the house convention (run FIRST, before any message)

Conventional Commits is this suite's fallback, not a universal truth. A repository that has demonstrably converged on another grammar gets that grammar; imposing the shipped default there produces commits that read as foreign in git log and in review. The precedence, highest first:

Tier Source Binding?
1 — configured commitlint.config.* · .gitmessage · a commit-msg hook (husky / lefthook / .git/hooks) · CONTRIBUTING.md § Commits · a CI job that validates subjects · release automation that PARSES subjects (semantic-release, changesets, git-cliff, conventional-changelog) yes — Class A, no approval needed
2 — measured + approved the consensus pass below, after the user says yes yes, for this repository
3 — measured, unapproved the same pass before the user answers no — advisory; report the mismatch, write Conventional
4 — default Conventional Commits yes

Release automation is the trap that makes tier 1 outrank tier 2 even when the history disagrees: a repo whose git log is 85 % [JIRA-123] Fix thing but whose manifest (package.json, composer.json, pyproject.toml, Cargo.toml) runs semantic-release or its ecosystem equivalent is a repo migrating toward Conventional Commits, and the measurement is reading its past, not its intent. Check for the parser before you trust the prevalence.

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.
