Write Pr Title

Use this skill when the user asks for a PR title, pull request title, what to call a PR-bound change, or title options for a branch intended for a PR.

Source of truth

• If the request targets an existing PR, base the title on that PR's exact current remote diff, not local-only WIP.
• If the request targets the current branch, base the title on the exact branch diff the user wants to publish.
• If the current branch already backs an open PR but local commits or worktree changes differ from the published PR tip, do not silently title the PR from that local-only state. Use the remote PR diff for PR-scoped requests, and ask a brief follow-up when a branch-scoped request is ambiguous between the published PR and unpublished local changes.
• Use changed files and the user's stated goal only after pinning the diff source above.
• Prefer the actual behavior change over implementation detail.

Diff check

1. Identify whether the user is asking about an existing PR, the current branch, or a provided diff.
2. For an existing PR, inspect the PR metadata and remote diff before writing the title.
3. For the current branch, inspect the in-scope branch diff or changed file summary before writing the title.
4. If the user supplied the relevant diff or change summary directly, use that as the source.
5. If the source is ambiguous between published PR state and unpublished local changes, ask one brief follow-up instead of guessing.

Title rules

• Return one short title unless the user asks for options.
• Use title case.
• Keep it direct and descriptive.
• Do not end with punctuation.
• Avoid vague prefixes like Updates, Various Fixes, or Cleanup unless the diff is truly only cleanup.

Writing heuristics

• Bug fix titles should usually start with Fix, Prevent, Handle, or Fallback.
• Feature titles should usually start with Add, Support, Show, Allow, or Track.
• Docs or workflow titles should usually start with Document, Clarify, or Add.
• Mention the user-facing surface or workflow when that is clearer than the implementation detail.

Output format

• Return only the proposed PR title unless the user asks for alternatives.
