systematic-debugging
Structured approach to diagnosing and fixing bugs. Use when a bug is reported, a test fails unexpectedly, behavior doesn't match expectations, or when "something is wrong" but the cause isn't clear. Triggers on "debug this", "why is this broken", "this doesn't work", "investigate this failure", unexpected test failures, or when multiple fix attempts have failed.
