Individual skill
test-guided-bug-detector
Analyze failing tests to detect functional bugs in code. Takes repository and failing test output as input, analyzes execution behavior, assertions, and stack traces to identify suspicious code regions and root causes. Use when debugging test failures, investigating regression bugs, or understanding why tests fail. Explains the bug mechanism, identifies affected code, and suggests fixes based on test expectations vs actual behavior.

# Test-Guided Bug Detector
Analyze failing tests to detect and explain functional bugs in code.
## Overview
When tests fail, they provide valuable clues about bugs in the code. This skill analyzes:
1. **Test failure output** - Error messages, stack traces, assertion failures
2. **Test expectations** - What the test expects to happen
3. **Actual behavior** - What actually happened
4. **Code execution path** - Which code was executed
5. **Suspicious patterns** - Common bug patterns that match the failure
