name	debugging-patterns
description	Root cause analysis frameworks including log-first investigation, git bisect correlation, and pattern-based diagnosis with confidence scoring.

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)
