Address PR Review Comments

Fetch all review comments for the current branch's open PR, present a numbered summary, and apply fixes for the comments the user selects.

Prerequisites

Verify gh authentication before doing anything else:

gh auth status

If unauthenticated, ask the user to run gh auth login, then stop.

Workflow

1. Resolve the PR

# if the user specified a PR number or URL:
gh pr view <number-or-url> --json number,url,headRefName

# otherwise (current branch):
gh pr view --json number,url,headRefName

Extract owner and repo from the returned url field — PR URLs have the form https://github.com/<owner>/<repo>/pull/<number>, so split on / to get the 4th and 5th segments. These are the base (target) repository coordinates, and are reliable even for cross-fork PRs.

2. Fetch comments

Run the following to get all review threads (inline) and conversation comments:

gh api graphql -f query='
query($owner:String!, $repo:String!, $number:Int!) {
  repository(owner:$owner, name:$repo) {
    pullRequest(number:$number) {
      number url title state
      comments(first:100) {
        nodes { id body author { login } createdAt }
      }
      reviews(first:100) {
        nodes { id state body author { login } submittedAt }
      }
      reviewThreads(first:100) {
        nodes {
          id isResolved isOutdated path line
          comments(first:100) {
            nodes { id body author { login } createdAt }
          }
        }
      }
    }
  }
}' -F owner=<owner> -F repo=<repo> -F number=<pr-number>

If GraphQL is unavailable, fall back to:

gh pr view <pr-number> -R <owner>/<repo> --json reviews,reviewRequests,comments

Note: the fallback output does not include thread-level isResolved/isOutdated fields. In fallback mode, treat all returned comments as actionable.

3. Present a numbered summary

List every unresolved comment/thread (or all comments in fallback mode) with a number, author, file/line (if inline), and a one-line description of the requested change. Example:

1. @alice [src/auth.ts:42] — Use bcrypt instead of MD5 for password hashing
2. @bob — Nit: rename `doThing` to `processPayload` for clarity
3. @alice [src/auth.ts:88] — Add input validation before DB query

4. Ask which to address

If the user already provided numbers in the skill argument, proceed with those. Otherwise ask:

Which comments should I address? (e.g. "1 3" or "all")

5. Apply fixes

For each selected comment:

• Read the relevant file and context.
• Apply the requested change.
• Note any cases where the comment is unclear or the fix has side effects — confirm with the user before proceeding.

6. Summarize

After all fixes, provide a brief summary listing which comments were addressed and any that were skipped (with reason).
