Update PR Summary

Update a PR title and description based on the complete changeset.

When explicitly invoked with extra text, treat that text as the PR number or URL.

Process

1. Fetch PR info

   • Use gh pr view <pr> --json title,body,baseRefName,headRefName.

2. Analyze the complete changeset

   • Use git diff <base-branch>...HEAD to review all committed changes in the branch.
   • Ignore unstaged changes.
   • Make the summary describe the full branch diff, not just the latest commit.

3. Generate the updated summary

   • Follow the create-pr skill format for title and body.
   • Start the title with a capital letter and a verb, with no fix: or feat: prefix.
   • Use plain language. Avoid jargon and internal shorthand unless an exact command or tool name is needed.
   • Keep the body to a single short section.
   • Include 1-2 sentences, a few bullets, and one usage snippet or before/after example when helpful.
   • Do not include test plans, changed file lists, or line-number links.

4. Apply the update

   • Use gh pr edit <pr> --title "..." --body "...".
