What problem does it solve? Turning a finished PRD into an actionable build order is hard: teams either plan horizontally (database first, then API, then UI) or guess at sequencing. This Skill reads a PRD, probes the existing codebase, and produces a roadmap of vertical, user-visible slices ordered by dependency. ## Core Features & Use Cases - PRD readiness scoring: Applies a 4-signal heuristic (vision, user stories, must-have FRs, business logic) before generating, warning when the PRD is too thin to roadmap. - Automated codebase baseline: Probes frontend, backend, data, auth, deploy, and observability layers via parallel subagents, reporting present/absent/partial with file evidence. - Lean framing interview: Asks at most three anchor questions (main goal, north-star slice, top blocker), each with a grounded recommendation and reasoned alternatives, then derives investment areas. - Use Case: After finishing a PRD for a fitness coaching app, run the Skill to get a roadmap.md listing foundation items (auth scaffold, deploy skeleton) and vertical slices (workout logging, progress dashboard) in dependency order, ready to hand each slice to a per-change planner. ## Quick Start Ask the AI to generate the roadmap from context/foundation/prd.md after your PRD is complete.
