Update PR Title Skill

Updates the current PR's title based on analysis of the changes.

Usage

Invoke with /update-pr-title or /update-pr-title <PR-number>.

Workflow

1. Get PR info: Run gh pr view to get the current PR (or specified PR number)
2. Get diff: Run gh pr diff to see the changes
3. Analyze: Review the diff to understand what changed
4. Generate title: Create a conventional commit-style title:
   • feat(scope): description for new features
   • fix(scope): description for bug fixes
   • refactor(scope): description for refactoring
   • docs(scope): description for documentation
   • chore(scope): description for maintenance
5. Update: Run gh pr edit --title "new title" to update the PR

Execution

Run autonomously without user confirmation. Execute all steps and report the result.

Step 1: Get PR Information

gh pr view --json number,title,headRefName

If a PR number was provided as an argument, use:

gh pr view <PR-number> --json number,title,headRefName

Step 2: Get the Diff

gh pr diff

Step 3: Analyze and Update

After analyzing the diff:

1. Determine the primary type of change (feat/fix/refactor/docs/chore)
2. Identify the scope (affected area/package)
3. Write a concise description of the change
4. Update the PR:

gh pr edit --title "type(scope): description"

Output

Report the old title and new title after updating.
