roadmap

Use to break a product idea into incremental steps and keep that decomposition living — one docs/roadmap.md with a destination sentence, the steps table (source-anchored, sized XS–XL or marked fog), the fog vocabulary (what's in scope but not yet formulated, what never graduates, which decisions are still open and who owns them), the dependency graph that owns every edge, and the execution path: dependency-respecting waves that show what can run in parallel (e.g. in worktrees) and what must wait. Triggers on "roadmap", "break this down", "decompose the idea", "what depends on what", "execution plan", "/awesome-sdd:roadmap". Takes any scope — a whole product, an epic, or a single feature. Reads docs/idea-brief.md or a PRD (+ design canon and architecture map when they exist; neither is required). It decomposes and orders — it is NOT a prioritization scorecard and NOT a dated Gantt; specify/ship keep step statuses in sync as features move.
