Gh PR Checks Plan Fix

Overview

Use gh to inspect PRs for:

• Failing CI checks (GitHub Actions)
• Merge conflicts
• Update Branch requirements (base branch advanced)
• Reviewer comments (review summaries, inline comments, issue comments)
• Change Requests from reviewers
• Unresolved review threads

Then propose a fix plan, implement after explicit approval, reply to every reviewer comment (with action taken or reason for not addressing), resolve all threads, and notify reviewers.

• Depends on the plan skill for drafting and approving the fix plan.

Prereq: ensure gh is authenticated (for example, run gh auth login once), then run gh auth status with escalated permissions (include workflow/repo scopes) so gh commands succeed.
