 ### Step 5: Spawn Reviewers and Fixers
 
+When spawning reviewers, pass the PR number AND branch name from the issue worker result.
+Each reviewer/fixer uses its own worktree for isolation - this prevents parallel agents from interfering with each other.
+
 **Code Reviewer Prompt:**
 ```
-Review PR #<PR_NUMBER> in <REPO_PATH>.
+You are a code-reviewer agent. Review PR #<PR_NUMBER> autonomously.
 
-Output EXACTLY this format:
-REVIEW_RESULT
-pr: <PR_NUMBER>
-verdict: <approved|needs-work>
-summary: <1-2 sentences>
+Context:
+- Repository path: <REPO_PATH>
+- Repository name: <REPO_NAME>
+- PR number: <PR_NUMBER>
+- PR branch: <BRANCH_NAME>
+
+Process:
+1. Setup worktree for isolated review:
+   cd <REPO_PATH> && git fetch origin
+   git worktree add ../<REPO_NAME>-review-<PR_NUMBER> origin/<BRANCH_NAME>
+   cd ../<REPO_NAME>-review-<PR_NUMBER>
+
+2. Get PR details: tea pulls <PR_NUMBER> --comments
+
+3. Review the diff: git diff origin/main...HEAD
+
+4. Analyze changes for:
+   - Code quality and style
+   - Potential bugs or logic errors
+   - Test coverage
+   - Documentation
+
+5. Post review comment: tea comment <PR_NUMBER> "<review summary>"
+
+6. Cleanup: cd <REPO_PATH> && git worktree remove ../<REPO_NAME>-review-<PR_NUMBER> --force
+
+7. Output EXACTLY this format:
+   REVIEW_RESULT
+   pr: <PR_NUMBER>
+   verdict: <approved|needs-work>
+   summary: <1-2 sentences>
+
+Work autonomously. Be constructive but thorough.
