+## Task
+
+Monitor and fix local + GitHub CI checks for the PR branch.
+
+## Context
+
+- Target branch: $ARGUMENTS (use current branch if not specified)
+
+## Instructions
+
+1. **Run Local Tests First** (faster feedback):
+   - Run tests locally
+   - If tests fail locally:
+     - Analyze the root cause
+     - Fix the issues in the code
+     - Re-run local tests to verify the fix
+     - Commit the fix with a clear message
+     - Push the changes
+   - If tests pass locally, proceed to step 2
+
+2. **Check CI Status**: Use the GitHub MCP tools
+
+3. **If CI is still running**:
+   - Wait 30-60 seconds
+   - Check again
+   - Repeat until all checks complete
+
+4. **If CI checks pass**: Report success and stop.
+
+5. **If CI checks fail**:
+   - Identify which checks failed
+   - Fetch the failure logs/details
+   - Analyze the root cause
+   - Fix the issues in the code
+   - Commit the fix with a clear message
+   - Push the changes
+   - Go back to step 1 to verify the fix (run local tests first)
+
+## Important
+
+- Always explain what failed and why before attempting fixes
+- Make minimal, targeted fixes - don't refactor unrelated code
+- If you cannot determine the fix, ask for help instead of guessing
