Write Teach Commit

Overview

Write a commit message that both triggers the workflow and gives $improve-add-skill enough context to learn the reusable correction.

The workflow only runs on pushes to branches matching ai-* when the head commit message starts with teach:. If the correction should not update .codex/skills/add/**, do not use a teach: subject.

Workflow

1. Inspect the user-provided diff, staged changes, PR review comments, .reason.md, and changed plugin list entries.
2. Identify the actual correction: a plugin moved between categories, an exclusion, a changed category path, or explicit rationale for why $add was wrong.
3. Separate evidence from the lesson: evidence may name repositories and files; the lesson should describe the reusable placement rule.
4. Draft a subject that starts exactly with teach: and names the generic lesson, not just the repository touched.
5. Add a short body when the subject alone cannot explain the correction.

Message Shape

Prefer this structure:

teach: <generic add-skill lesson>

Correction:
- <owner/repo>: <old category or decision> -> <new category or decision>

Reusable lesson:
- <category/exclusion rule that would have prevented the mistake>

Evidence:
- <short source, such as review comment, .reason.md row, or file path>

Keep the subject concise. Use the body for category paths and details.

Quality Rules

• Start the first line with teach: exactly; Teach:, fix: teach, and body-only markers will not trigger the workflow.
• Use full category paths from .reason.md or the markdown heading hierarchy when available.
• Make the reusable lesson domain-based, such as user workflow or plugin purpose, rather than implementation surface.
• For exclusions, state the exclusion trigger explicitly, such as fork, colorscheme, no README, non-English README, config repo, or sample plugin.
• Do not use teach: for formatting-only, ordering-only, badge-only, typo-only, or ambiguous corrections.

Output

When the user asks for a commit message, output one message only. Prefer a fenced text block unless the user requests a command.

If there is no safe reusable lesson, say that teach: should not be used and provide a normal non-triggering commit subject instead.
