What's inside

The instructions your model reads when the skill loads.

SKILL.md24 linessingle file

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)
