# 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.

- Title: a short human headline, capital first letter, no `fix:` or `feat:` prefix. Lead with the outcome, punchy over exhaustive.

- - Body: open on why it exists, then show it with a `diff`, a before/after, or a runnable CLI snippet.

+ - Body: open on why, then short scannable bullets (one point each) plus a `diff`, before/after, or runnable CLI snippet.

- Numbers win: benchmarks, counts, speedups, comparisons over adjectives.

- - One read, one section. No headers, no bullet dump. Plain words, no buzzwords.

+ - One read, one section, no headers. Plain words, no buzzwords.

- No test plans, file lists, or line links.

4. **Apply the update**

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