# Stage Gate Reviewer This skill decides whether a stage may proceed. A stage cannot pass by self-declaration. ## Input Artifacts - `00-stage.json` - `00-artifact-registry.json` - Current stage artifacts - Evidence inventory when verifying completion ## Output Artifact - `docs/full-stack-development/requirements/<feature-slug>/00-gate-report.md` ## Required MCP Tool - `review_stage_gate` - `review_requirement_workspace_stage` - `review_visual_evidence` - `review_completion_gate` ## Hard Stops - No visual design without approved requirements. - No UI implementation without approved Pencil/Figma visuals reviewed by `review_visual_evidence`. - No verification pass without test, build, screenshot when UI applies, code review, and acceptance evidence. ## Pressure Test Responsibility - Jump-to-design requests must block. - Jump-to-code requests must block. - A `visualDesignApproved` boolean without visual evidence must block. - Verification with missing evidence must block. ## Next Gate - The next stage named by `review_stage_gate.nextAllowedStage`.
