What problem does it solve? Slice-level QA confirms each piece was built correctly, but nothing verifies the whole phase works as an integrated product with real data. This Skill runs a structured end-to-end phase test and produces a single gate decision: ready to deploy or hold with specific items to resolve. ## Core Features & Use Cases - Seven-stage specialist sequence: environment readiness, use case creation, data validation, scenario testing, regression checking, acceptance review, and a final gate decision. - Derived test plan: builds test scenarios from the discovery brief, design artifact, edge cases, done criteria, and to-be process map rather than inventing them. - Gate decision with receipts: outputs a HOLD or OPEN verdict with named open issues, and appends a phase completion record to the backlog when the gate opens. - Use Case: After all Phase 1 slices reach In Test, invoke the skill to walk every user journey against real APIs, catch regressions between slices, and confirm the phase delivers the original discovery intent before deploying. ## Quick Start Invoke the phase test by saying: run the phase test for this phase now that all slices are in test.
