## Pattern-Based Diagnosis

- Check patterns.md for known gotchas matching the error
- Cross-reference with common patterns: null pointer, race condition, resource leak, config error
- Rate root cause confidence (>=80% to proceed with fix)

## Evidence Collection

- Stack traces with full call chain
- Error messages with context
- Exit codes from reproduction attempts
- Git blame/log for change correlation
- Environment differences (if applicable)

## When to Use

- During DEBUG workflow investigation phase
- When BUILD tests fail unexpectedly
- When reviewing error handling gaps

## Agents Used

- `bug-investigator` (primary consumer)
- `silent-failure-hunter` (pattern reference)
