 The **Design system** dropdown ships with 71 built-in systems — 2 hand-authored starters (Neutral Modern, Warm Editorial) and 69 product systems imported from [`awesome-design-md`](https://github.com/VoltAgent/awesome-design-md), grouped by category (AI & LLM, Developer Tools, Productivity, Backend, Design Tools, Fintech, E-Commerce, Media, Automotive). Pick one to skin every prototype in that brand's aesthetic.

 This Quickstart is the runnable seed of the spec in [`docs/`](docs/). The spec describes where this grows (see [`docs/roadmap.md`](docs/roadmap.md)). Highlights:
 
 - `docs/architecture.md` proposes Next.js; we picked Vite for a simpler dev loop. The daemon contract is identical, so migrating is a port, not a rewrite.
-- `docs/skills-protocol.md` describes the full `ocd:` frontmatter (typed inputs, sliders, capability gating). This MVP reads `name` / `description` / `triggers` / `ocd.mode` / `ocd.design_system.requires` only — extend `daemon/skills.js` to add the rest.
+- `docs/skills-protocol.md` describes the full `od:` frontmatter (typed inputs, sliders, capability gating). This MVP reads `name` / `description` / `triggers` / `od.mode` / `od.design_system.requires` only — extend `daemon/skills.js` to add the rest.
 - `docs/agent-adapters.md` foresees richer dispatch (capability detection, streaming tool-calls). Our `daemon/agents.js` is a minimal dispatcher — enough to prove the wiring.
 - `docs/modes.md` lists four modes: prototype / deck / template / design-system. We ship skills for the first two; the picker already filters by `mode`.
