Tonight's learnings:
- Parallel Codex army for batch PR reviews
- Fetch PR refs: git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'
- Use git diff origin/main...origin/pr/XX (don't checkout)
- Post results with gh pr comment
- Successfully reviewed 13 PRs in parallel! 🦞

-### PR Review Tips
-- Fetch PR refs first: `git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'`
-- Tell Codex to use: `git diff origin/main...origin/pr/XX`
-- Don't let it checkout branches (conflicts with parallel reviews)
+### Tips for PR Reviews
+- **Fetch refs first:** `git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'`
+- **Use git diff:** Tell Codex to use `git diff origin/main...origin/pr/XX`
+- **Don't checkout:** Multiple parallel reviews = don't let them change branches
+- **Post results:** Use `gh pr comment` to post reviews to GitHub
