This is a systematic debugging skill that walks you through the standard process: reproduce, isolate, analyze, fix. It includes a solid table of common error categories (null/undefined, type errors, async issues, race conditions), language-specific debug commands for JavaScript, Python, and Go, and practical patterns like divide-and-conquer and minimal reproduction. The skill activates when you mention bugs, errors, or debugging explicitly. Honestly, this is mostly a reference guide rather than something that fundamentally changes how Claude debugs. The real value is in the structured checklist and error lookup tables if you're stuck on a particular error message or need a methodical approach when you're in the weeds.
