What GSD Debug does

GSD Debug systematically debugs issues using the scientific method with subagent isolation, maintaining persistent state across context resets. It orchestrates a debugger subagent and session manager, supports a diagnose-only mode, and lets users list, check status, or continue debug sessions.

GSD Debug is cataloged under Quality on DirSkills. GSD Debug comes from a repository tagged claude-code, context-engineering, meta-prompting and spec-driven-development.
