What problem does it solve? Turning a finished PRD into an ordered build plan is hard: teams either guess what to build first or over-plan with timelines that immediately become fiction. This Skill reads a PRD, probes the existing codebase, and produces a dependency-ordered roadmap of vertical, user-visible slices ready for per-change planning. ## Core Features & Use Cases - PRD readiness scoring: Applies a 4-signal heuristic (vision, user stories, must-have FRs, business logic) and warns before generating a roadmap from a hollow PRD. - Automated codebase baseline: Runs parallel subagent probes across frontend, backend, data, auth, deploy, and observability layers so foundations reflect what actually exists. - 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 without extra questions. - Dependency-ordered output: Emits context/foundation/roadmap.md with F-NN foundations and S-NN slices, blocking unknowns, and parallelizable items — no time estimates or implementation details. - Use Case: After finishing a PRD for a new SaaS product, invoke the Skill to get a sequenced list of milestones like "auth scaffold → first end-to-end user flow → dashboard", each ready to hand to a per-change planner. ## Quick Start Run /10x-roadmap after your PRD exists at context/foundation/prd.md to generate a sequenced roadmap of vertical slices.
