What problem does it solve? Coordinating the implementation of every feature in a PRD across backend, frontend, and testing layers is error-prone and often results in stub components, missing states, and orphaned code. This Skill automates Stage 5 of the Transmute Plan Casting pipeline by orchestrating agent teams to build the complete product with quality gates between features. ## Core Features & Use Cases - Feature Queue Orchestration: Builds a dependency-ordered implementation queue from the PRD feature map (P0 through P3), splitting large features into sub-features and handling blocked or circular dependencies. - Per-Feature Agent Cycle: Spawns backend, frontend, and E2E test teammates sequentially for each feature, with a lead-run quality gate enforcing typecheck, tests, traceability, and anti-stub scans. - Session Recovery & Completion: Resumes interrupted sessions from plancasting/_progress.md, re-runs features flagged by the Stage 5B audit, and produces a final implementation report with launch readiness assessment. - Use Case: After completing PRD, scaffolding, and CLAUDE.md setup, run this Skill to implement all 23 features of your product — each with real backend logic, composed frontend components, and Playwright E2E tests — ending with 100% PRD coverage. ## Quick Start Ask the agent to run Stage 5 feature implementation from the PRD and build the complete product.
