Quality Assurance Features ​

15. Nyquist Validation ​

Purpose: Map automated test coverage to phase requirements before any code is written. Named after the Nyquist sampling theorem — ensures a feedback signal exists for every requirement.

Requirements:

  • REQ-NYQ-01: System MUST detect existing test infrastructure during plan-phase research
  • REQ-NYQ-02: System MUST map each requirement to a specific test command
  • REQ-NYQ-03: System MUST identify Wave 0 tasks (test scaffolding needed before implementation)
  • REQ-NYQ-04: Plan checker MUST enforce Nyquist compliance as 8th verification dimension
  • REQ-NYQ-05: System MUST support retroactive validation via /gsd-validate-phase
  • REQ-NYQ-06: System MUST be disableable via workflow.nyquist_validation: false

Produces: \{phase\}-VALIDATION.md — Test coverage contract

Retroactive Validation (/gsd-validate-phase [N]):

  • Scans implementation and maps requirements to tests
  • Identifies gaps where requirements lack automated verification
  • Spawns auditor to generate tests (max 3 attempts)
  • Never modifies implementation code — only test files and VALIDATION.md
  • Flags implementation bugs as escalations for user to address

16. Plan Checking ​

Purpose: Goal-backward verification that plans will achieve phase objectives before execution.

Requirements:

  • REQ-PLANCK-01: System MUST verify plans against 8 quality dimensions
  • REQ-PLANCK-02: System MUST loop up to 3 iterations until plans pass
  • REQ-PLANCK-03: System MUST produce specific, actionable feedback on failures
  • REQ-PLANCK-04: System MUST be disableable via workflow.plan_check: false

17. Post-Execution Verification ​

Purpose: Automated check that the codebase delivers what the phase promised.

Requirements:

  • REQ-POSTVER-01: System MUST check against phase goals, not just task completion
  • REQ-POSTVER-02: System MUST produce VERIFICATION.md with pass/fail analysis
  • REQ-POSTVER-03: System MUST log issues for /gsd-verify-work to address
  • REQ-POSTVER-04: System MUST be disableable via workflow.verifier: false

18. Node Repair ​

Purpose: Autonomous recovery when task verification fails during execution.

Requirements:

  • REQ-REPAIR-01: System MUST analyze failure and choose one strategy: RETRY, DECOMPOSE, or PRUNE
  • REQ-REPAIR-02: RETRY MUST attempt with a concrete adjustment
  • REQ-REPAIR-03: DECOMPOSE MUST break task into smaller verifiable sub-steps
  • REQ-REPAIR-04: PRUNE MUST remove unachievable tasks and escalate to user
  • REQ-REPAIR-05: System MUST respect repair budget (default: 2 attempts per task)
  • REQ-REPAIR-06: System MUST be configurable via workflow.node_repair_budget and workflow.node_repair

19. Health Validation ​

Command: /gsd-health [--repair]

Purpose: Validate .planning/ directory integrity and auto-repair issues.

Requirements:

  • REQ-HEALTH-01: System MUST check for missing required files
  • REQ-HEALTH-02: System MUST validate configuration consistency
  • REQ-HEALTH-03: System MUST detect orphaned plans without summaries
  • REQ-HEALTH-04: System MUST check phase numbering and roadmap sync
  • REQ-HEALTH-05: --repair flag MUST auto-fix recoverable issues

20. Cross-Phase Regression Gate ​

Purpose: Prevent regressions from compounding across phases by running prior phases' test suites after execution.

Requirements:

  • REQ-REGR-01: System MUST run test suites from all completed prior phases after phase execution
  • REQ-REGR-02: System MUST report any test failures as cross-phase regressions
  • REQ-REGR-03: Regressions MUST be surfaced before post-execution verification
  • REQ-REGR-04: System MUST identify which prior phase's tests were broken

When: Runs automatically during /gsd-execute-phase before the verifier step.

21. Requirements Coverage Gate ​

Purpose: Ensure all phase requirements are covered by at least one plan before planning completes.

Requirements:

  • REQ-COVGATE-01: System MUST extract all requirement IDs assigned to the phase from ROADMAP.md
  • REQ-COVGATE-02: System MUST verify each requirement appears in at least one PLAN.md
  • REQ-COVGATE-03: Uncovered requirements MUST block planning completion
  • REQ-COVGATE-04: System MUST report which specific requirements lack plan coverage

When: Runs automatically at the end of /gsd-plan-phase after the plan checker loop.
