commit is a skill for Claude Code from juxt/claude-plugins. It costs 98 tokens per session (2,123 once invoked), scanned A, original, MIT.

A procedure for creating a Git commit with a message body that explains why the change was made.

In plain words
What is it for?
Use it when staging related changes and writing or amending a commit message, especially when the body needs to explain design decisions.
Why use it?
It keeps each commit focused and records the reasoning future developers need when reviewing the project history.

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 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Contextual Git Commit

Interpret MUST, MUST NOT, SHOULD, SHOULD NOT, MAY, etc. per RFC 2119.

The user MAY provide the commit headline as an argument (e.g. /chalk:commit fix: boolean logic error in expression.clj).

Before you draft

A commit body is an explanation artefact and MUST be drafted in the chalk voice, not your own default prose habits.

You MUST load these skills first:

  • chalk:voice — the audience, the specification register, the mindmap structure, the line-format rule.

  • chalk:code-comments — the body is where a comment's design rationale belongs, so this is the moment the misfiled ones surface.

Your responsibilities

  1. Stage relevant changes.

    Each commit MUST be an atomic, cohesive unit of change — a transition from one valid state to another — and unrelated changes MUST NOT be staged together.

    • If two changes don't make sense independently, they're one commit; if they're distinct, they're two.

    • Keep unrelated bugfixes separate.

    • Where reasonable, separate behaviour-preserving changes (refactorings) from behaviour-advancing ones.

  2. Weed the staged comments.

    Delegate to the weed-comments agent, passing the paths of the staged files and nothing else.

    • You MUST NOT tell it what the change is for. Not the issue, not the problem, not what you decided. It stands in for a reader who has none of that, and briefing it makes it a second opinion from your own context rather than a first opinion from the reader's.

    • Its deletions apply. They land in the working tree and you stage them; you do not review them back into place. The user sees them in the commit diff, which is the human review point.

    • Its Misfiled list is input to Draft the body — a comment deleted for being design rationale is rationale the body now has to carry.

    • Where a comment survives, its Kept line names the misunderstanding it prevents; that belongs in neither the body nor the code.

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.
