Home — choose an artifact type, enter a brief, and set the design system, working directory, and model before you start.

Plugins — browse official skills by category, search the catalog, and launch a workflow with Try it.

Design System — extract and refine a brand's visual language, preview the result, and create with it in the same workspace.

Prototype — generate or reconstruct web experiences, inspect the rendered page, and iterate with the agent in place.	Deck — create multi-slide presentations, review thumbnails and speaker notes, and export when ready.
Mobile app — generate and polish mobile interfaces in a device preview, with the conversation, output files, and next-step actions beside it.	Image — generate visual assets from the project conversation, preview the result at full size, then download or open it.
Document — create polished, multi-page guides and editorial documents, inspect the rendered layout, and export or share when ready.	HyperFrame — build code-driven motion graphics, preview the animation inside Studio, and export the finished video.

--print` for a dry-run preview · `--uninstall` to remove · full list with `od mcp install --help`. ¹ Automatic MCP configuration for Claude Desktop is currently supported on macOS and Windows only.

**No CLI installed?** The BYOK proxy at `POST /api/proxy/{anthropic,openai,azure,google,ollama,senseaudio}/stream` gives you the same loop (no process spawn) — paste `baseUrl` + `apiKey` + `model`, with presets for OpenAI, Atlas Cloud, Anthropic, Azure OpenAI, Google Gemini, Ollama, LM Studio, vLLM, or any OpenAI-compatible endpoint. Atlas Cloud uses `https://api.atlascloud.ai/v1` with your own key and OpenAI-compatible model ids such as `qwen/qwen3.5-flash`. Per-target SSRF protection blocks internal IPs / link-local / CGNAT at the daemon edge. Runtime definitions live in [`apps/daemon/src/runtimes/defs/`](apps/daemon/src/runtimes/defs/), with registration and shared stream handling under [`apps/daemon/src/runtimes/`](apps/daemon/src/runtimes/). See [`docs/agent-adapters.md`](docs/agent-adapters.md) for the adapter contract. --- ## Demo Four core product categories, all rendered by a coding agent running on your laptop. Click a thumbnail to see the real example. ### 1 · Prototypes — web · desktop · mobile The default output surface. Single-page HTML artifacts that read your `DESIGN.md` and render in a sandboxed iframe.

Web prototype — an editorial dashboard with scrollbars, KPIs, and charts. Rendered straight from design-templates/dating-web/.

Mobile app prototype — a three-screen gamified flow with XP ribbons and quest detail. Hand off straight to Cursor / Codex / Claude Code to turn into React/Next/Vue.

### 2 · Live artifacts & dashboards Live dashboards, decision rooms, KPI walls — single-page artifacts that pull data through a tweaks panel and stay editable in place.

Live dashboard — an editable KPI wall whose tweaks panel surfaces the parameters worth nudging. The agent emits a manifest, and the iframe re-renders without a reload.	Decision room — a multi-source briefing artifact for product / research / ops meetings.
GitHub-style dashboard — repo metrics presented as a live artifact.	Flow live-dashboard template — a domain-specific KPI template, branded through the active DESIGN.md.

### 3 · Decks — magazine decks, weekly updates, pitches

Deck mode (guizang-ppt) — magazine layouts, WebGL hero, P0/P1/P2 checklists. Bundled verbatim from op7418/guizang-ppt-skill with its original license preserved.

Swiss International-style deck — grid-anchored, monochrome accents. One of 15 deck templates and 36 themes under design-templates/html-ppt-*/.

Every deck exports to **HTML** (single file, inlined assets), **PDF** (browser print, deck-aware), **PPTX** (agent-driven skill), **ZIP** (archive), or **Markdown**. ### 4 · Images — `gpt-image-2`, ImageRouter, custom API

Illustrated city food map Hand-drawn editorial travel poster

Cinematic elevator scene Single-frame editorial still

3D stone staircase Hewn-stone infographic

Glamorous portrait Editorial studio shot

**93 ready-to-replicate prompts** live in [`prompt-templates/`](prompt-templates/) — preview thumbnails, full prompt body, target model, aspect ratio, and source attribution. One click drops a brief into the composer. ### 5 · Video & HyperFrames — agent-native motion graphics **[HyperFrames][hyperframes]** is HeyGen's open-source, agent-native video framework, integrated as a first-class citizen in OpenDesign. The agent writes HTML + CSS + GSAP, and HyperFrames renders it to a deterministic MP4 via headless Chrome + FFmpeg. Pair it with **Seedance 2.0** for cinematic t2v / i2v, **Veo 3 / Sora 2 / Kling 2** for routed model variants, and **Suno v5 / Lyria 2** for the audio layer.

[hyperframes]: https://github.com/heygen-com/hyperframes --- ## Why OpenDesign > **In April 2026, Anthropic released Claude Design — the first time an LLM stopped writing prose and started delivering design artifacts directly.** It went viral. But it stayed closed-source, paid-only, cloud-only, locked to Anthropic's model, Anthropic's skills, Anthropic's surface. No checkout, no self-host, no Vercel deploy, no swap-in-your-own-agent. OpenDesign (OD) is the open-source alternative. Same loop, same artifact-first mental model, none of the lock-in: - 🤖 **Agent-native, model-agnostic.** We don't ship an agent. The `claude` / `codex` / `cursor-agent` / `copilot` / `hermes` / `kimi` already on your `PATH` are the design engine. Swap with one click. - 🧠 **Brand-grade by default.** Every render reads the active package's `DESIGN.md` as the core brand contract. 151 design-system packages ship with the repo; legacy packages may be `DESIGN.md`-only, while newer packages can add `manifest.json`, `tokens.css`, components, assets, and provenance. Drop a folder in, the picker finds it. - 🖥️ **Local-first, BYOK at every layer.** Native desktop apps for macOS (Apple Silicon + Intel) and Windows (x64). Linux AppImage on the optional release lane. Product analytics and session replay are consent-gated; scrubbed safety and reliability telemetry is always on. Before describing daemon data paths, contributors and operators MUST read `AGENTS.md` → **Daemon data directory contract**. This README MUST NOT restate it. - 🌍 **Composable on four planes.** **Plugins** carry runnable workflows · functional **skills** carry agent behavior · **design templates** carry rendering blueprints · **design systems** carry the brand. All four use portable, versionable directories that anyone can author and publish. - 🔁 **Refresh an existing codebase.** Hand a `git` repo + `DESIGN.md` to the agent and it refactors your real components to the brand spec. Dedicated plugins migrate Figma / Pencil workflows into React / Next.js / Vue code. - 🔒 **Privacy by conviction.** Everything runs where your data lives — your laptop, your team's server, your Vercel project. When the network is needed, the BYOK proxy is SSRF-guarded. ### Comparison | | Claude Design | Figma | Lovable / v0 / Bolt | **OpenDesign** | |---|---|---|---|---| | Open source | ❌ | ❌ | ❌ | **✅ Apache-2.0** | | Self-host / desktop | ❌ | ❌ | ❌ | **✅ macOS + Windows + Docker + Vercel web** | | Agent-native (runs in your CLI) | Anthropic only | ❌ | Cloud agent only | **✅ 25 CLIs + BYOK** | | Brand-grade `DESIGN.md` | Proprietary | Theme JSON | Limited tokens | **✅ 151 systems shipped** | | Skills / plugins / templates | Closed | Plugin store | Closed | **✅ 100+ functional skills · rendering templates · 277 plugins** | | HyperFrames (HTML→MP4) | ❌ | ❌ | ❌ | **✅ First-class** | | Refresh an existing repo to brand | ❌ | ❌ | ❌ | **✅ via agent + `DESIGN.md`** | | Minimum billing | Pro / Max / Team | Pro / Org | Pro / Team | **BYOK · any compatible endpoint** | --- ## Quick start ### 🖥️ Download the desktop app (recommended — zero config) The fastest way to use OpenDesign. No Node, no pnpm, no clone. - **macOS** (Apple Silicon · Intel x64) → [**open-design.ai**](https://open-design.ai/?utm_source=github&utm_medium=referral&utm_content=readme_download_macos) or [GitHub Releases](https://github.com/nexu-io/open-design/releases) - **Windows** (x64) → [**open-design.ai**](https://open-design.ai/?utm_source=github&utm_medium=referral&utm_content=readme_download_windows) or [GitHub Releases](https://github.com/nexu-io/open-design/releases) - **Linux** (AppImage, optional lane) → [GitHub Releases](https://github.com/nexu-io/open-design/releases) After install: the app auto-detects every coding-agent CLI on your `PATH`, loads 100+ functional skills, the separate rendering-template catalog, and 151 design systems, and lets you type a brief in the entry view. ### 🤖 Install into your coding agent (no UI) You can use OpenDesign without ever opening the GUI — call it as a skill, plugin, or MCP server inside Claude Code, Codex, Cursor, Copilot, OpenClaw, Antigravity, Hermes, Kimi, and more. If you installed the macOS desktop app via the DMG or Homebrew cask, your shell may still resolve `od` to Apple's built-in `/usr/bin/od` octal-dump utility. In that case, open **Settings → MCP server** in the desktop app and copy the client-specific snippet; it uses absolute paths and does not rely on the bare `od` command. ```bash # One-line install into the agent you're using: od mcp install # = claude | codex | reasonix | raven | cursor | copilot | openclaw # | antigravity | pi | vibe | hermes | cline | kimi | kiro # | trae | opencode # Hosted equivalent for curl-based setup: curl -fsSL https://open-design.ai/install.sh | sh -s ``` `install.sh` is a thin shell wrapper around `od mcp install`; it exists so the hosted URL returns shell instead of the landing-page HTML fallback and fails fast if your shell resolves a non-Open-Design `od` binary. > **macOS / WSL2 users:** `/usr/bin/od` is a system octal-dump command and can > shadow OpenDesign's `od` command. Desktop-app users should prefer the > **Settings → MCP server** snippet; WSL2 users should follow the > [`WSL2 setup guide`](docs/wsl-setup.md) first. Then, inside the agent: ``` > Use open-design to generate a landing page with the Linear design system ``` In a filesystem-backed local CLI run, the agent composes the selected functional skill or design template with your `DESIGN.md`, writes the canonical project files, and OpenDesign previews those files. A BYOK/plain-API run without filesystem tools instead returns one complete `` block. ### 🐳 Run with Docker ```bash git clone https://github.com/nexu-io/open-design.git cd open-design/deploy cp .env.example .env echo "OD_API_TOKEN=$(openssl rand -hex 32)" >> .env docker compose up -d # open http://127.0.0.1:7456 ``` If the browser asks for credentials, use `open-design` as the username and the `OD_API_TOKEN` value from `deploy/.env` as the password. This keeps Docker bridge traffic authenticated without requiring host networking. API clients can keep using `Authorization: Bearer `. ### 🚀 Deploy on Sealos [](https://sealos.io/products/app-store/open-design/) The Sealos App Store template runs the published OpenDesign Docker image with persistent workspace storage and Basic Auth on the public proxy. For custom public or shared Docker deployments, follow the reverse-proxy and `OPEN_DESIGN_ALLOWED_ORIGINS` guidance in [`deploy/README.md`](deploy/README.md#local-compose). ### 🧑‍💻 Run from source ```bash git clone https://github.com/nexu-io/open-design.git cd open-design corepack enable && pnpm install pnpm tools-dev run web ``` Open the URL printed by `tools-dev`; development ports are allocated dynamically unless you pass explicit port flags. Node `~24`, pnpm `10.33.x`. WSL2 users, see [`docs/wsl-setup.md`](docs/wsl-setup.md); native Windows users, see [`docs/windows-troubleshooting.md`](docs/windows-troubleshooting.md). Full quickstart, env vars, Nix flake, and packaged build flow → [`QUICKSTART.md`](QUICKSTART.md). ### A full workflow — from brief to artifact `brief → plugin → direction → design system → artifact → handoff → memory` 1. **A PM submits a brief.** The plugin picker offers landing page · pitch deck · dashboard · social post · PM spec · OKR scorecard… 2. **A designer (or the agent) locks the direction.** No brand? Pick from 5 curated directions. Have a brand? Drop a screenshot / URL → the agent connects GitHub, imports Figma, and codifies a reusable `DESIGN.md`. 3. **The agent creates the first deliverable.** Plugin + functional skill or design template + `DESIGN.md` are bound. Filesystem-backed CLI runs write canonical project files and the preview follows them; BYOK/plain-API runs without file tools return one complete `` block. 4. **Hand off to engineering.** The artifact is real HTML/CSS — drop it into Cursor, Codex, or Claude Code to keep building as code. Or export PPTX / PDF / MP4 straight to marketing. 5. **OpenDesign gets smarter as you use it.** Your screenshots, fonts, palettes, and confirmed artifacts accumulate as defaults for the next session. Less rework, less drift. --- ## Use OpenDesign from your coding agent OpenDesign ships a **stdio MCP server** and per-agent **install scripts**. Any MCP-compatible agent in another repo can read files from your local OpenDesign projects directly — tokens CSS, JSX components, entry HTML — as a structured API queryable by name. The agent always sees the live file, not a stale export. ```bash # One-line install (16+ CLIs supported): od mcp install # Then the agent can: od project list --json od files list --json od files read od plugin list --json od skills list --json ``` **Why MCP?** Exporting and re-attaching a zip every iteration breaks flow. MCP exposes the design source directly — the agent always sees the live file. **For an agent starting from scratch,** the installer places `~/.config//open-design.json` (or the platform equivalent) plus a copy-paste MCP snippet. Cursor gets a one-click deeplink; Claude Code gets a `claude mcp add-json` one-liner; every other agent gets JSON in the schema its config expects. On macOS desktop installs, prefer that Settings snippet over typing bare `od mcp install ` in Terminal, because `/usr/bin/od` may win on PATH. Full per-agent flow → **Settings → MCP server** in the desktop app, or [`docs/agent-adapters.md`](docs/agent-adapters.md). **Security model.** Read-only by default, the daemon binds to `127.0.0.1`, and SSRF is blocked at the proxy edge. LAN exposure requires an explicit `OD_BIND_HOST` plus `OD_ALLOWED_ORIGINS`. Connector credentials and live-artifact preview routes stay loopback-only regardless. **Internally-hosted model endpoints.** To prevent SSRF, the daemon blocks provider base URLs that resolve to private/internal address ranges (RFC1918, link-local, CGNAT, and cloud-metadata IPs) by default, surfacing `Internal IPs blocked`. If you run an internally-hosted gateway (e.g. LiteLLM or Ollama on a VPN-only `10.x`/`192.168.x` address), opt that host out with `OD_ALLOWED_INTERNAL_HOSTS=,,...` — a comma- or whitespace-separated list of bare hostnames or IPs (`10.0.0.5`, `litellm.internal.corp`; a `host:port` or full URL is accepted and reduced to its hostname; IPv6 must be bracketed, e.g. `[fd00::1]`). The allowlist is strict opt-in (empty by default), exact-host (no subdomain/substring matching), and applies **only** to provider endpoints you configure (connection test, model discovery, BYOK chat). It deliberately does **not** relax the guard on download URLs returned inside upstream responses, which stay blocked. A malformed entry — or CIDR notation, which is not supported — is dropped with a warning rather than silently trusted, so a typo never quietly widens (or fails to widen) the guard. Allowlisting a hostname trusts whatever it resolves to (like `OD_ALLOWED_ORIGINS`); allowlist the resolved IP instead if you want the DNS-resolved address re-checked. --- ## Skills and design templates **100+ functional skills ship in [`skills/`](skills/)**. Each follows the Agent Skills [`SKILL.md`][skill] convention and supplies reusable agent behavior, references, or utilities. Renderable starters live separately in [`design-templates/`](design-templates/); they may also use `SKILL.md`, but they populate the design-template catalog rather than the functional-skill registry. Two **modes** anchor the design-template catalog: `prototype` (web/mobile/desktop single-page artifacts) and `deck` (horizontal-swipe presentations). Other templates cover `image`, `video`, `audio`, and utility surfaces. The **`scenario`** field groups templates by audience: `design` · `marketing` · `operation` · `engineering` · `product` · `finance` · `hr` · `sale` · `personal`. | Design template | Mode | Scenario | What it produces | |---|---|---|---| | [`web-prototype`](design-templates/web-prototype/) | prototype | design | Default landing page / hero | | [`saas-landing`](design-templates/saas-landing/) | prototype | marketing | Hero / features / pricing / CTA | | [`dashboard`](design-templates/dashboard/) | prototype | operation | Admin / analytics (with sidebar) | | [`mobile-app`](design-templates/mobile-app/) | prototype | design | iPhone 15 Pro / Pixel framed app | | [`mobile-onboarding`](design-templates/mobile-onboarding/) | prototype | design | Splash · value-prop · sign-in flow | | [`social-carousel`](design-templates/social-carousel/) | prototype | marketing | 3-card 1080×1080 carousel | | [`email-marketing`](design-templates/email-marketing/) | prototype | marketing | Table-fallback-safe brand email | | [`magazine-poster`](design-templates/magazine-poster/) | prototype | marketing | Single-page magazine layout | | [`motion-frames`](design-templates/motion-frames/) | prototype | marketing | Looping CSS motion hero | | [`sprite-animation`](design-templates/sprite-animation/) | prototype | marketing | 8-bit pixel animated explainer | | [`pm-spec`](design-templates/pm-spec/) | prototype | product | PM spec doc (with TOC + decision log) | | [`team-okrs`](design-templates/team-okrs/) | prototype | product | OKR scorecard | | [`eng-runbook`](design-templates/eng-runbook/) | prototype | engineering | Incident runbook | | [`finance-report`](design-templates/finance-report/) | prototype | finance | Exec finance summary | | [`hr-onboarding`](design-templates/hr-onboarding/) | prototype | hr | Role onboarding plan | | [`guizang-ppt`](design-templates/guizang-ppt/) | deck | marketing | Magazine-style web PPT (deck default) | | [`html-ppt-*`](design-templates/) | deck | marketing | 15 deck templates × 36 themes (master template in [`design-templates/html-ppt/`](design-templates/html-ppt/)) | | [`hyperframes`](design-templates/hyperframes/) | video | marketing | HTML → MP4 motion graphics (HeyGen OSS framework) | | [`critique`](design-templates/critique/) | utility | design | Five-dimensional self-critique scoresheet | | [`tweaks`](design-templates/tweaks/) | utility | design | AI-emitted tweaks-panel manifest | Full protocol and directory split → [`docs/skills-protocol.md`](docs/skills-protocol.md). Registry endpoints: `GET /api/skills` for functional skills and `GET /api/design-templates` for rendering templates. --- ## Design Systems **151 brand-grade design-system packages centered on `DESIGN.md`** ship with the repo. Legacy packages may contain only that Markdown contract; newer packages can also carry `manifest.json`, compiled `tokens.css`, component fixtures, assets, and provenance evidence. The catalog mixes upstream-derived systems with project-owned additions; [`design-systems/README.md`](design-systems/README.md) records the package shape and provenance. Switch a system → the next render uses the new tokens.

[acd2]: https://github.com/VoltAgent/awesome-design-md --- ## Plugins **277 official plugins plus 183 remixable reference examples** live in [`plugins/_official/`](plugins/_official/). Each entry is a portable plugin directory anchored by `open-design.json` plus the payload required by its type: for example `SKILL.md` for agent workflows, `template.json` for media templates, or `DESIGN.md` for design-system entries. Jump straight to a category: | Category | Count | Contents | |---|---|---| | [`scenarios/`](plugins/_official/scenarios/) | 13 | Complete design scenarios — [`od-default`](plugins/_official/scenarios/od-default/), [`od-design-refine`](plugins/_official/scenarios/od-design-refine/), [`od-figma-migration`](plugins/_official/scenarios/od-figma-migration/), [`od-code-migration`](plugins/_official/scenarios/od-code-migration/), [`od-react-export`](plugins/_official/scenarios/od-react-export/), [`od-nextjs-export`](plugins/_official/scenarios/od-nextjs-export/), [`od-vue-export`](plugins/_official/scenarios/od-vue-export/), [`od-media-generation`](plugins/_official/scenarios/od-media-generation/), [`od-new-generation`](plugins/_official/scenarios/od-new-generation/), [`od-tune-collab`](plugins/_official/scenarios/od-tune-collab/), [`od-plugin-authoring`](plugins/_official/scenarios/od-plugin-authoring/), [`od-share-to-community`](plugins/_official/scenarios/od-share-to-community/), [`od-web-effect-extractor`](plugins/_official/scenarios/od-web-effect-extractor/) | | [`image-templates/`](plugins/_official/image-templates/) | 45 | One-shot image prompts — editorial, cinematic, product, portrait | | [`video-templates/`](plugins/_official/video-templates/) | 63 | HyperFrames / Seedance / Veo motion templates | | [`design-systems/`](plugins/_official/design-systems/) | 143 | Brand `DESIGN.md` wrapped as plugins | | [`atoms/`](plugins/_official/atoms/) | 13 | Reusable UI fragments (buttons, heroes, KPI cards) | | [`examples/`](plugins/_official/examples/) | 183 | Remixable reference outputs | Also [`plugins/community/`](plugins/community/) for community plugins and [`plugins/registry/`](plugins/registry/) for the publishing flow. ### What plugins can do - 🤖 **Run in any coding agent** — [Claude Code](docs/agent-adapters.md), Codex, Cursor, Copilot, [OpenClaw](https://github.com/openclaw/openclaw), [Antigravity](https://antigravity.google), Hermes, Kimi… through the same skill protocol the agent already knows. - 🔁 **Migrate Figma / Pencil workflows** → React, Next.js, or Vue source. See [`od-figma-migration`](plugins/_official/scenarios/od-figma-migration/). - 🛠️ **Refresh an existing codebase to a brand spec** — point a plugin at a `git` repo + `DESIGN.md`, get a PR. See [`od-code-migration`](plugins/_official/scenarios/od-code-migration/). - 💾 **Persist custom workflows** — your team's reusable templates sit next to the shipped ones. ### Using plugins Plugins are at full parity across the **web UI** and the **`od` CLI** — same `/api/plugins` endpoints, pick whichever fits. **In the desktop / web app:** open the **Plugin** page to browse the marketplace and click **Install**; inside a project's Studio, plugins appear as composer chips you click to apply (with the inputs they declare). **On the command line** (runs without a UI — this is the path external agents use): ```bash od plugin list # list installed plugins (--task-kind / --mode / --tag filters) od plugin search "landing page" # search by keyword od plugin info od-default # inspect a plugin's metadata, inputs, capabilities od plugin install od-figma-migration # install from a registry; also accepts ./local-folder or an https://… link od plugin apply od-default --input brief="a one-page pitch for our seed round" od plugin upgrade od-default # upgrade od plugin uninstall od-default # uninstall ``` Every command supports `--json`, so you can pipe it through `jq` / `xargs` into automation. ### Building a plugin An OpenDesign plugin requires `open-design.json` plus the payload required by its type. A workflow skill or scenario also includes `SKILL.md`; manifest-only template and design-system entries use their own payloads instead: ``` my-plugin/ ├── open-design.json ← required: marketplace metadata + inputs + pipeline + capabilities ├── SKILL.md ← required for agent-skill/scenario entries; omitted for other plugin types ├── README.md ← optional: usage, install, registry links ├── preview/ ← optional: index.html / poster.png (strongly recommended for visual plugins) └── examples/ ← optional: concrete use cases ``` Core `open-design.json` fields: `specVersion` (currently `1.0.0`), `name` (stable ID), `version` (semver), optional `compat.agentSkills[].path` (points at `./SKILL.md` when the entry exposes an Agent Skill), `od.kind` (`skill` / `scenario` / `atom` / `bundle`), `od.taskKind` (`new-generation` / `figma-migration` / `code-migration` / `tune-collab`), `od.mode` (the output surface, e.g. `prototype` / `deck` / `live-artifact` / `image` / `video` / `hyperframes` / `audio` / `design-system` / `scenario`), `od.capabilities[]` (**declare the minimum** — a restricted install grants only `prompt:inject` by default), `od.inputs[]` (apply-time parameters). Scaffold + validate locally: ```bash od plugin scaffold --id my-plugin --title "My Plugin" # generate the skeleton od plugin validate ./my-plugin # check manifest / file layout pnpm guard && pnpm --filter @open-design/plugin-runtime typecheck ``` Full field set and runtime contract → [`plugins/spec/SPEC.md`](plugins/spec/SPEC.md); developing a plugin with a coding agent → [`plugins/spec/AGENT-DEVELOPMENT.md`](plugins/spec/AGENT-DEVELOPMENT.md); copy-paste minimal templates → [`plugins/spec/examples/`](plugins/spec/examples/). ### Contributing a plugin 1. Drop the plugin folder into [`plugins/community/`](plugins/community/) (third-party plugins), or — to ship it bundled with OpenDesign — into the matching tier of [`plugins/_official/`](plugins/_official/). 2. Pass validation: `od plugin validate`, `pnpm guard`, `pnpm --filter @open-design/plugin-runtime typecheck`. 3. Fill the PR using the template in [`plugins/spec/CONTRIBUTING.md`](plugins/spec/CONTRIBUTING.md) (ID, version, lane, mode, capabilities, trigger examples; attach a screenshot / preview for visual plugins). 4. To publish to an external registry (skills.sh / ClawHub / standalone GitHub) → [`plugins/spec/PUBLISHING-REGISTRIES.md`](plugins/spec/PUBLISHING-REGISTRIES.md). Plugin registry endpoint: `GET /api/plugins`.

Many of the most-used skills, design systems, and plugins were written by people outside the core team. ### 🎯 Where to start (max leverage, min change) | Want to ship… | How | Where | |---|---|---| | A new functional **skill** | Drop a folder with `SKILL.md` + optional `assets/` + `references/` | [`skills/`](skills/) · spec in [`docs/skills-protocol.md`](docs/skills-protocol.md) | | A new rendering **design template** | Add a renderable `SKILL.md` bundle | [`design-templates/`](design-templates/) | | A new **design system** | Drop a package centered on `DESIGN.md`; add `manifest.json`, `tokens.css`, components, assets, or provenance when needed | [`design-systems//`](design-systems/) | | A new **plugin** | Drop `open-design.json` + the type-specific payload under a category folder | [`plugins/community/`](plugins/community/) · spec in [`plugins/spec/SPEC.md`](plugins/spec/SPEC.md) · agent dev guide in [`plugins/spec/AGENT-DEVELOPMENT.md`](plugins/spec/AGENT-DEVELOPMENT.md) | | Support a new **coding-agent CLI** | One runtime definition + registry entry; add a parser only for a new wire format | [`apps/daemon/src/runtimes/defs/`](apps/daemon/src/runtimes/defs/) | | Fix a bug or polish UI | Browse the [`good-first-issue`](https://github.com/nexu-io/open-design/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) label | [Issues →](https://github.com/nexu-io/open-design/issues) | | Translate the docs | Update the `README..md` files | [`TRANSLATIONS.md`](TRANSLATIONS.md) | ### 🤖 Contributing as an agent If *you are the agent reading this*, the fastest path is: ```bash # 1. Boot locally git clone https://github.com/nexu-io/open-design.git cd open-design && corepack enable && pnpm install pnpm tools-dev run web # 2. Find a good-first-issue and assign yourself gh issue list --label "good first issue" --state open --limit 20 gh issue develop # create a branch and worktree # 3. Make the change, run the checks pnpm guard && pnpm typecheck pnpm --filter @open-design/ test # 4. Open the PR gh pr create --fill ``` Full agent-friendly contribution flow, code style, and PR bar → [`CONTRIBUTING.md`](CONTRIBUTING.md) ([Deutsch](docs/i18n/CONTRIBUTING.de.md) · [Français](docs/i18n/CONTRIBUTING.fr.md) · [简体中文](docs/i18n/CONTRIBUTING.zh-CN.md) · [日本語](docs/i18n/CONTRIBUTING.ja-JP.md) · [한국어](docs/i18n/CONTRIBUTING.ko.md) · [Português](docs/i18n/CONTRIBUTING.pt-BR.md) · [ภาษาไทย](docs/i18n/CONTRIBUTING.th.md)). ### 🏅 OpenDesign Fellow program We're recruiting **OpenDesign Fellows** around the world — Fellows shape the product alongside the core team, represent OpenDesign officially in their region, and grow the community locally, backed by funded support ($1,000 / MR), free LLM credits, and a direct review track. Details → [`MAINTAINERS.md`](MAINTAINERS.md) and the announcement on [Discord](https://discord.gg/mHAjSMV6gz). --- ## Maintainers They carry a lot of the load — daily maintenance, review, and community support.
