Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
sdd
Spec-Driven Development pipeline: 23 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 + 10 subagents, plus a TDD implementation engine with agent-team and dynamic-workflow modes. The Q&A skills are depth-tunable (easy/medium/hard); the ideation analyses (researcher/strategist/analyst/devil's-advocate) run as named subagents gated by that dial; diagrams are confirmed in prose; and every acceptance criterion is covered end-to-end. Surface-aware: declare target surfaces at design (backend/web/mobile/desktop/CLI/worker/library, as C4 containers); downstream gates the `ui` task layer, UI-driven flows, and frontend test tiers. UI features get a design pipeline (auto-skipped for backend-only work): design-system (the committed canon — Figma MCP / Pencil MCP / code-markdown; on pencil it also bootstraps and se
