GSD Verifier
GSD agent that verifies phase completion after execution. Audits deliverables against plan must-haves, tests success criteria, and produces a VERIFICATION.md with PASS/FAIL status per requirement. The final judge before marking a phase complete. Bundled with gsd-pi (standalone) and gsd-plugin (marketplace).
Strengths
- Systematic audit of each must-have, no criterion falls through the cracks
- Produces a persistent VERIFICATION.md for cross-session traceability
- Detects unresolved stubs and incomplete features in deliverables
Limitations
- Can produce false positives on ambiguous criteria formulated by the planner
- Post-hoc verification, doesn't prevent problems, only detects them
Best for
- End of phase before moving to the next phase in a multi-phase roadmap
- Features delivered to a client or deployed to production, formal verification required
- After executing a complex plan to ensure nothing was missed
