Agnosticui
AgnosticUI Local (v2) is a CLI-based UI component library that copies components directly into your project. Works with AI tools, agent-driven UIs, and prompt-ready workflows.

Source-first architecture
AgnosticUI components are copied into your project at install time.
They live in your repo (not hidden inside node_modules):
- Full control over the source
- Native integration with your framework
- AI-readable, high-fidelity context
You own the source (and the Context)
cd your-project
npx agnosticui-cli init --framework vue # or react, lit, svelte
npx agnosticui-cli add Button Card Input
The component source lands directly in your project. Readable, editable, and yours.
src/
components/
ag/
Button/
Button.vue ← your file now
Button.css ← your tokens now
Button.test.ts ← your tests now
Components land under src/components/ag/ by default: a dedicated namespace that keeps AgnosticUI components separate from your own. Configurable if you prefer otherwise.
🤖 AI-Native by Design
Because the code is local, it solves the "Black Box" problem of traditional libraries hidden in node_modules.
Cursor · Claude · Copilot · Windsurf · Aider · Gemini · Replit · Kiro · Antigravity
Every tool sees the raw source. This creates a high-fidelity environment for Generative UI and Agent-driven interfaces:
- Reduce Hallucination: No more "invented" props or APIs. Since the LLM reads local files like any other code, it knows exactly what is possible.
- Better Token Efficiency: Using semantic HTML and standard CSS provides "clean context." Agents spend fewer tokens to understand the UI, leading to faster, more accurate generations.
- Agent Skills: Treat AgnosticUI Playbooks as pre-defined skills. Use them to prompt an agent to scaffold complex, accessible workflows (Login, Onboarding, Discovery Dashboard, Support Center, Data Grids) using the local components it already "sees."
This is the architecture for the next era of development: context-aware, framework-agnostic, and AI-ready.
The schema-driven layer ships with three companion documents:
v2/docs/sdui-architecture.md— full system architecture: codegen pipeline, node graph model, renderers, CI gates, and key design decisionsv2/docs/llm-prompt-guide.md— copy-paste system prompt template and few-shot examples for generating validAgNode[]graphsv2/docs/schema-coverage.md— per-component SDUI coverage registry, renderer parity status, and omission reasons
Built once. Runs everywhere.
AgnosticUI's components are authored as Lit Web Components, a standards-based layer over native Custom Elements. The CLI wraps them for your framework at copy time.

AI Playbooks: AI-Prompt-Driven UI Components
Playbooks (Login Form, Onboarding Wizard, Discovery Dashboard, Support Center, Data Grid, Blog / Article Reader, Landing / Marketing Page) demonstrate modular, prompt-driven UI components. Each Playbook can be used in agent systems, for context-aware applications, or to create generative UI patterns.
| Playbook | What it builds | | ------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | Login Form | Responsive login: mobile, floating card, two-column desktop; works with AI prompt-driven generation | | Onboarding Wizard | Multi-step flow with progress, validation, and skip logic; supports agent-assisted workflows | | Discovery Dashboard | Dashboard shell with header, sidebar, and data regions — ideal for agent-generated interfaces | | Support Center | Help center with search, categories, and article layout; integrates with prompt-driven workflows | | Data Grid | Responsive, interactive data grid with sorting, filtering, and multiple view modes; compatible with agent-driven and context-aware interfaces | | Blog / Article Reader | Typography-first editorial layout with scroll-aware components and in-article search highlighting; theme switcher, dark/light mode, React/Vue/Lit demos | | Landing / Marketing Page | Polished product marketing page with hero, features, testimonials, pricing, and FAQ; animated components, theme switcher, dark/light mode, React/Vue/Lit demos |
Each Playbook on the docs site includes live StackBlitz examples for React, Vue, and Lit, and ships with:
PROMPT-3-FRAMEWORKS.md: one prompt to generate the pattern across all three frameworks- Skin switcher to preview your theme tokens instantly
Fully prompt-ready for agent-driven UI generation. Drop a Playbook prompt into Cursor, Claude Code, or Copilot and watch it assemble Input, Button, Card, and FormGroup correctly on the first try — because it has the full recipe, not just a component reference.
The prompts are yours to adapt. Feed one to your LLM as a crash course in AgnosticUI's patterns, fork it for your own stack, or use it as a blueprint for writing Playbooks around your own UI patterns.
Theme skins via CSS custom properties
AgnosticUI components expose their entire visual surface through CSS custom properties. Swap a skin and every component updates; no code changes, no find-and-replace.
/* Base tokens are required, then layer your skin on top */
@import "./components/ag/styles/ag-tokens.css";
@import "./components/ag/styles/ag-tokens-dark.css";
@import "./components/ag/styles/brutalist-light.css";
@import "./components/ag/styles/brutalist-dark.css";
Hand it to a designer. Get back a token file. Import it. Done.
Quick Start
React
cd my-react-app
npx agnosticui-cli init --framework react
npx agnosticui-cli add Button Card Input
Vue
cd my-vue-app
npx agnosticui-cli init --framework vue
npx agnosticui-cli add Button Card Input
Svelte
cd my-svelte-app
npx agnosticui-cli init --framework svelte
npx agnosticui-cli add Button Card Input
Lit / Web Components directly
cd my-lit-app
npx agnosticui-cli init --framework lit
npx agnosticui-cli add Button Card Input
After running add, your terminal prints the exact import path for your project. No guessing. Supports agent-driven and prompt-ready UI workflows.
