+   - Look for the line `- [ ] $ARGUMENTS: test_xxx test_yyy ...` to get the direct dependent tests
+   - Run those tests to collect failures:

+   - For example, if deps output shows `- [ ] linecache: test_bdb test_inspect test_linecache test_traceback test_zipimport`, run:
+     ```
+     cargo run --release -- -m test test_bdb test_inspect test_linecache test_traceback test_zipimport 2>&1 | grep -E "^(FAIL|ERROR):"

    - For each failure, use the Task tool with `general-purpose` subagent to investigate:
      - Subagent should follow the `/investigate-test-failure` skill workflow
