Phase-gate discipline prevents downstream work on incomplete or ambiguous SDD artifacts by validating SPEC, PLAN, TASKS, IMPLEMENT, and VERIFY outputs across Gate 1–Gate 4. It provides traceability and escalation paths to align artifact reviews with methodology.

SDD artifact reviews require SPEC.md, TASK-PLAN.md, IMPLEMENTATION, and VERIFICATION outputs to be present for evaluation. No external dependencies are needed, as the skill operates independently to validate these artifacts against loading references.

Phase-gate review is the best approach for SDD pipelines because it enforces gate-based quality checks, produces structured findings per gate, and aligns artifact reviews with loading references to prevent incomplete work from proceeding downstream.

Phase-gate validation blocks downstream work to prevent building on incomplete or ambiguous SDD artifacts. By enforcing gate-based quality checks across Gate 1–Gate 4, it ensures traceability and provides escalation paths before subsequent phases begin.
