We split this skill into the rules it gives an agent

2 rules. 0 are common, 1 is distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 4 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Check it: Write the draft to a file, then commit check --file <path> --key <KEY>.

    line 37
  2. Distinctive:

    One logical change per commit: If the subject needs an "and", it is probably two commits.

    line 50

“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

write-commit

wb <args>    # wb not on PATH: python <this skill's directory>/../../lib/wb.py <args>

This skill writes the message. Committing stays the user's call: the CLI prints the command and runs it only for an explicit --execute.

Steps

  1. Learn the house style. commit convention. It reports what this repo already does — conventional commits, ticket-prefixed subjects, or free-form — from its own history, plus the author identity and whether it matches the context. Follow it; a message in a different style is noise in the log forever. If it reports free-form and the team has decided to adopt a style, record it once with commit convention --set <style> — do not impose one silently.
  2. See what changed. git diff for the files, review context if you need the zones. If a plan exists: sdd get <KEY> --section summary gives the objective in one line.
  3. Write it.
    • Subject: imperative, specific, under 72 characters, no trailing period. "fix expired coupon charging the card" — not "fixes" and not "bug fix".
    • Body, when the change is not self-evident: why, not what. The diff already says what. Wrap at 72.
    • Reference the ticket key if the repo's history does.
    • BREAKING CHANGE: in the body if a contract changed.
  4. Check it. Write the draft to a file, then commit check --file <path> --key <KEY>. On pass with a key it is saved to .workflow/<KEY>/commit.txt; on failure nothing is saved and the reasons are listed. Fix the message, not the check.
  5. Hand it over. Show the message. git commit <KEY> prints the exact commit command, carrying the saved message and the author the context expects; add --execute only if the user asked you to commit. It refuses on a protected branch and with nothing staged — choosing what goes in a commit stays theirs.

Rules

  • One logical change per commit. If the subject needs an "and", it is probably two commits.
  • Never describe what you did not do. No "add tests" in the subject when no test file changed.
  • No unfinished markers. wip, fixup! and squash! are rejected.
  • Never put a credential in a message. The check refuses anything that looks like one.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
