conventional-commits

conventional-commits is a skill for Claude Code from Jamie-BitFlight/claude_skills. It costs 59 tokens per session (4,268 once invoked), scanned A, original, MIT.

A guide for writing Git commit messages in the Conventional Commits format, a shared structure such as `feat`, `fix`, or `docs`. The format can be read by tools that generate changelogs and decide semantic version numbers.

In plain words
What is it for?
Use it to write or review commit messages, configure commit validation, generate changelogs, and support automated versioning.
Why use it?
It makes a project's change history easier for people and automation to understand. Consistent messages also help identify features, fixes, documentation changes, and breaking changes.

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 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 7d 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.

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.
