+Addresses PR review feedback end-to-end: reads unresolved comment threads, makes code changes, commits, responds to each reviewer on GitHub, resolves threads, posts a summary comment, dismisses stale "changes requested" reviews, and re-requests review.
+
+**Workflow:**
+1. **Identify PR** — from a PR number, URL, or auto-detect from the current branch
+2. **Fetch threads** — single GraphQL call for all review threads and reviews (up to 100 threads, 20 comments each)
+3. **Detect bot reviewers** — identifies AI bots (copilot, coderabbitai, etc.) to avoid `@mentioning` them (which re-triggers bot reviews)
+4. **Validate each comment** — reads the actual code and checks repo patterns before implementing. Catches false positives where a reviewer's suggestion conflicts with repo conventions
+5. **Categorize and present** — groups comments into code changes, questions, false positives, and discussion items. **Pauses for user approval**
+6. **Address feedback** — makes targeted code changes, delegates complex refactors to `/lfx-backend-builder` or `/lfx-ui-builder`
+7. **Validate** — runs format, lint, build before committing
+8. **Commit** — single commit per review iteration with detailed summary crediting reviewers
+9. **Respond and resolve** — replies to each thread on GitHub, resolves addressed threads
+10. **Push and summarize** — pushes changes, posts a summary comment on the PR
+11. **Refresh reviews** — dismisses stale "changes requested" reviews, re-requests review from addressed reviewers
+
+**Key behaviors:**
+- Validates reviewer suggestions against actual repo patterns before implementing — prevents introducing anti-patterns from misguided feedback
+- Handles false positives gracefully with respectful, evidence-backed explanations
+- Credits human reviewers with `@mentions`, but never `@mentions` bot reviewers (avoids re-triggering AI review tools)
+- Idempotent — safe to re-run; only picks up threads that are still unresolved
+- Delegates complex multi-file changes to builder skills when appropriate

 ### `/lfx-test-journey` — Multi-Branch Journey Testing
 
 Combines feature branches from one or more repos into isolated git worktrees for end-to-end journey testing. Use this when you have a user journey spread across multiple PRs/branches and need to test everything together before merging.
