systematic-debugging

Quick Review

Exceptional systematic debugging skill with comprehensive methodology. The description clearly indicates when to use it (any bug/test failure/unexpected behavior), and the four-phase process (Root Cause Investigation, Pattern Analysis, Hypothesis Testing, Implementation) provides extensive task knowledge with concrete steps, examples, and anti-patterns. Structure is excellent with clear phases, quick reference tables, and well-organized supporting documents. The 'Iron Law' and multi-component diagnostic instrumentation are particularly strong. Novelty is high - enforcing disciplined root-cause analysis before fixes meaningfully reduces wasted debugging cycles that would consume many AI tokens through trial-and-error. Minor room for improvement: the description could be slightly more explicit about the four phases to aid initial invocation, but overall this is a highly valuable, well-documented skill that addresses a common failure mode (premature fixing).
