Find and fix bugs, error analysis
debug
by ZachArticulateV
"Find the root cause of a bug and fix it with proof: reproduce the failure, test competing explanations, trace the cause from trigger to symptom, and fix it behind a regression test. Use when something is broken, failing, flaky, slower than it used to be, or behaving differently than expected."

troubleshooting
by jkitchin
Systematic debugging and problem diagnosis using structured troubleshooting methodologies applicable to any domain - technical issues, process failures, system problems, or general obstacles. Use when users report errors, describe malfunctions, encounter unexpected behavior, or need help diagnosing root causes. Triggers include 'debug this,' 'troubleshoot,' 'why isn't this working,' 'getting an error,' 'something's wrong with,' 'how do I fix,' or any problem description.
systematic-testing
by xbklairith
Use when writing tests, debugging failures, or investigating bugs - provides TDD guidance, test generation patterns, systematic debugging framework. Activates when user says "write tests", "this test fails", "debug this", mentions "TDD", "test coverage", or encounters errors/bugs.
