commit

Write one good commit for a completed change.

Commit only. This skill never runs tests, typecheck, lint, or a build — not in any mode, --yes included. Something else already verified; if nothing did, that is a gap in the caller, not work for this skill to absorb.

--yes runs non-interactively: no confirmation prompt. It is not permission to push or amend.

1. Resolve the change and the issue reference

Resolve the change by trying, in order:

1. An explicit change name argument
2. The current branch name (feat/<name>, fix/<name>)
3. The most recently modified openspec/changes/*/ directory

Ask only when the session is interactive and all three fail. Under --yes, never ask — report which rungs were tried and stop with a one-line message.

Extract an issue reference from the branch when one was not passed: feat/RD-65-task-page → RD-65 · fix/PROJ-123-login-bug → PROJ-123

If the branch looks like a feature branch but no reference was found:

⚠️ No issue reference found. Branch <name> looks like a feature branch — pass one as /interlock:commit <REF> to avoid rewriting the message later.

Interactive: wait for the user to confirm or supply one. Under --yes: emit that single line, proceed without a ref, and surface it again in the final report. On main, develop, or any branch without a feat//fix/ prefix, proceed silently — the reference is genuinely optional there.

2. Gather context

openspec status --change "<name>" --json
git status --short
git diff --stat

Read proposal.md for the one-line intent, design.md for scope, and the checked items in tasks.md for what was actually done. Inspect the diff to confirm the message matches reality rather than matching the plan.

3. Compose the message

<type>(<scope>): <verb phrase, imperative, lowercase>

Summary of changes:
- <outcome, not task completion>
- <outcome>

Refs: <ISSUE-REF>

• Scope is the issue reference when one exists (feat(RD-65): …), otherwise the primary module or feature area (feat(tasks): …).
• Summary bullets describe outcomes, not "completed task 2.3".
• Refs: line appears only when a reference exists. Omit the line entirely otherwise — never write Refs: none.

4. Preview and commit

Show the full message. Interactive: ask "Commit with this message?" and allow edits. Under --yes: print it and commit.

Stage by naming every path explicitly, then commit.

Guardrails

• Never git add -A or git add .. Name every path. Leave unrelated dirty files unstaged.
• Never push. --yes is not that permission.
• Never amend unless the user explicitly asks and the amend conditions hold. --yes is not that permission.
• Never run tests, typecheck, lint, or build — in any mode.
• Never re-implement or quick-fix failing code here. If the tree looks broken: interactive, warn and ask whether to commit anyway; under --yes, commit and report the observation. Never start a verify/fix loop either way.

5. Report

Commit hash and subject, files committed, anything left unstaged, and the warning from step 1 if it fired. Suggest the next step: /interlock:settle to open or update the pull request.
