Debugging

Comprehensive debugging framework combining systematic investigation, root cause tracing, defense-in-depth validation, and verification protocols.

Core Principle

NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST

Random fixes waste time and create new bugs. Find the root cause, fix at source, validate at every layer, verify before claiming success.

When to Use

Always use for: Test failures, bugs, unexpected behavior, performance issues, build failures, integration problems, before claiming work complete

Especially when: Under time pressure, "quick fix" seems obvious, tried multiple fixes, don't fully understand issue, about to claim success

The Four Techniques

1. Systematic Debugging (references/systematic-debugging.md)
