Processing Done by Skill

1. Fetches PRs via GitHub GraphQL API where you're requested as reviewer
2. Calculates human-readable ages and review time estimates
3. Parses CI status, review status (counting unique reviewers), conflict status
4. Extracts PR summaries from descriptions (omitted for dependency updates)
5. Tracks viewing history (marks new PRs with 🆕 badge)
6. Groups PRs into categories (Feature/Bug → Chores → Dependency Updates)
7. Sorts by age (oldest first) within each category
8. Assigns sequential numbers across all PRs
9. Formats as markdown with proper spacing and blank lines
10. Stores lookup mapping in ~/.claude/.cache/fetching-github-prs-to-review.json
11. Updates viewing history in ~/.claude/.cache/fetching-github-prs-to-review-history.json

Notes

• Filters out PRs from ignored repos (currently: recursionpharma/build-pipelines)
• FEATURE/BUG PRs: Not chores, not dependency updates, not drafts
• CHORES: PRs with titles starting with "chore:"
• DEPENDENCY UPDATES: All dependency updates (dependabot, bump PRs, etc.)
• Unique reviewer count: Counts each person once, shows their most recent review state
• Time estimates: Based on total lines changed (0-50: 5min, 51-200: 10min, etc.)
• Formatting: Space before PR numbers prevents markdown list parsing; blank lines separate PRs
