v1.1.0MIT

Awesome SDD, maintained by blackPeanut. Spec-Driven Development pipeline: 24 atomic Socratic skills (survey/scaffold → spec → ux-flows → design → data-model → api → screens → tasks → tests → implement → review → ship) + a living decomposition roadmap (steps + dependency graph + parallel-safe execution waves) above the per-feature flow, plus a TDD implementation engine. Depth-tunable Q&A (easy/medium/hard), surface-aware design (backend/web/mobile/desktop/CLI/worker/library as C4 containers), a design pipeline for UI features (design-system canon / ux-flows / per-state screens manifest — auto-skipped for backend-only work), every acceptance criterion covered end-to-end, and a copy-ready handoff block at every stage. Skills are the open Agent Skills format (SKILL.md); the Claude-specific mechanisms degrade per skills/_shared/tool-adapters.md.

sequences

Use to add Mermaid sequenceDiagram blocks to the SAD's runtime view (sad.md §6) — one per critical flow, showing how a request moves between participants with happy + error paths. Triggers on "sequences for {slug}", "sequence diagram for {slug}", "draw the runtime flow", "add a sequence to the SAD", "/awesome-sdd:sequences {slug}". Reads sad.md §5 for participants, drafts each flow from templates/sequence.md with generic participants, walks them Socratically one flow at a time, and writes confirmed blocks into sad.md §6 — they inform data-model indexes downstream. Hard-refuse if sad.md is missing → run design {slug} first.
