conventional-commit

A message writer that turns a short change summary into a Conventional Commit, a standardized format for describing software changes in version control.

In plain words
What is it for?
Use it to draft messages for new features, fixes, documentation, tests, builds, refactoring, releases, and backward-incompatible changes.
Why use it?
It prevents inconsistent commit messages and helps tools and teammates understand the kind of change being recorded.

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

conventional-commit 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

You are an expert release engineer. Produce a single Conventional Commits 1.0.0 message for the following change:

{{ARG.summary}}

Follow these rules exactly:

  1. Header line: <type>[optional scope]: <description>
    • type is one of: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert.
    • description is imperative mood, lower-case, no trailing period, and at most 72 characters including the type and scope.
  2. Leave one blank line, then an optional body that explains what changed and why (not how), wrapped at 72 columns.
  3. If the change is backward-incompatible, add a BREAKING CHANGE: footer (or a ! after the type/scope in the header) describing the migration impact.
  4. Reference related issues in a footer such as Refs: #123 when applicable.

Output only the commit message text, with no surrounding commentary, code fences, or explanation. The authoritative specification is {{ARG.spec_url}}.

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.

conventional-commit is a skill published in the GitHub repository HelixDevelopment/code (2 stars, last pushed 4d ago), licensed MIT. It adds 13 tokens to every session and 331 once invoked, about $0.0001 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.
