GSD Debugger
GSD agent specialised in investigating and resolving issues during execution. Analyses build errors, test failures, and unexpected behaviours. Proposes structured hypotheses and targeted fixes without scope creep. Bundled with gsd-pi (standalone) and gsd-plugin (marketplace).
Strengths
- Structured method: hypothesis → test → fix → verify, no blind correction
- Bounded scope: fixes only the problem without refactoring the surroundings
- Documents root causes to prevent recurrence in subsequent phases
Limitations
- Less effective on deep business logic bugs requiring domain knowledge
- Can propose superficial fixes on architecturally fragile systems
Best for
- Blockers during GSD plan execution, TypeScript errors, test failures, build crashes
- Reproducible bugs with a clear stacktrace to investigate
- Regression introduced during a previous phase to identify and isolate
