Can this skill help with legacy codebases?

Yes, it includes a specialized Phase 3 workflow for existing logic that uses git blame and predictive testing to ensure old features don't break during fixes.

How does the Debugging Workflow skill trigger?

It automatically activates when Claude detects error logs, test failures, or specific keywords like 'exception' or '3회 실패' in the terminal or log files.

Does it provide documentation for resolved bugs?

Yes, the skill includes a Phase 4 documentation step that records symptoms, causes, and prevention strategies in a KNOWN_ISSUES.md file.

What is the Phase Gate model?

It is a safety mechanism that prevents the AI from modifying code until it has formulated a hypothesis, created a verification plan, and confirmed the evidence.

Security & Testing

Automates a multi-phase debugging protocol to identify root causes and verify hypotheses before applying code changes.

The Systematic Debugging Workflow skill implements a rigorous Phase 0-3 (D0-D4) protocol for Claude, ensuring that bugs are solved through evidence-based analysis rather than trial and error. It automatically triggers upon test failures or error logs, guiding the AI through log insertion, problem classification, and structured hypothesis verification. By enforcing a 'Phase Gate' model, it prevents regressions and side effects while maintaining a history of known issues to streamline future troubleshooting and knowledge sharing.
