+# EDDI Chat UI — AI Agent Guidelines
+
+> **This file is loaded by AI coding assistants. Follow ALL rules below.**
+
+## 1. Project Context
+
+**eddi-chat-ui** is a standalone React 19 chat widget for [EDDI](https://github.com/labsai/EDDI) agents. Built with Vite + TypeScript 5.7, vanilla CSS with CSS custom properties, and `react-markdown` for rich message rendering.
+
+### Tech Stack
+
+| Technology     | Version | Purpose                        |
+| -------------- | ------- | ------------------------------ |
+| React          | 19      | UI framework                   |
+| TypeScript     | 5.7     | Type safety                    |
+| Vite           | 6       | Build tool + dev server        |
+| Vitest         | 3.x     | Unit testing (jsdom)           |
+| react-markdown | 9.x     | Markdown rendering in messages |
+
+### Ecosystem
+
+- **EDDI backend** — Quarkus REST API at `/agents/{env}/{agentId}`, serves chat UI from `META-INF/resources/`
+- **EDDI Manager** — Admin UI with embedded chat panel, shares API patterns
+- All repos at `c:\dev\git\`
+
+---
+
+## 2. Project Structure
+
+```
+src/
+├── api/            # API layer
+│   ├── chat-api.ts     # Pure fetch functions (start, read, send, stream, undo, redo)
+│   └── demo-api.ts     # Mock API for demo mode
+├── components/     # UI components
+│   ├── ChatWidget.tsx      # Main orchestrator (lifecycle, SSE, query params)

+│   ├── MessageBubble.tsx   # User/agent messages with markdown
+│   ├── ChatInput.tsx       # Auto-grow textarea, Enter/Shift+Enter
+│   ├── QuickReplies.tsx    # Pill buttons for suggested replies
+│   ├── Indicators.tsx      # Typing (dots) + Thinking (brain) indicators
+│   └── ScrollToAgenttom.tsx  # Floating scroll button
+├── hooks/
+│   └── useTheme.ts     # Dark/light/system theme with localStorage
+├── store/
+│   └── chat-store.tsx  # Context + useReducer state management
+├── styles/
+│   ├── variables.css   # CSS custom properties (dark/light tokens)
+│   └── chat.css        # All component styles (BEM naming)
+└── types.ts            # Shared TypeScript types
+```
+
+---
+
+## 3. Key Conventions
+
+1. **CSS** — BEM naming: `.chat-header__logo`, `.message--user`, `.quick-replies__btn`. No Tailwind.
+2. **State** — `ChatProvider` → `useChatState()` / `useChatDispatch()`. No prop drilling.
+3. **API** — Pure `fetch` in `chat-api.ts`. SSE streaming uses `AsyncGenerator`.
+4. **Testing** — Wrap components in `<ChatProvider>`. Mock `window.matchMedia` in `test-setup.ts`.
+5. **Demo mode** — `/chat/demo/showcase` uses `demo-api.ts`. Check with `isDemoMode()`.
+6. **Query params** — `hideUndo`, `hideRedo`, `hideNewConversation`, `hideLogo`, `theme`, `title`.
+
+---
+
+## 4. Build & Deploy
+
+Production build goes to **EDDI backend** at `src/main/resources/META-INF/resources/`:
+
+```bash
+npm run build    # Outputs to EDDI backend resources
+```
+
+---
+
+## 5. Mandatory Workflow
+
+1. **Before work**: `git status`, read this file + any `changelog.md`
+2. **During work**: Commit with `feat(chat-ui):` / `fix(chat-ui):`. Each commit must build.
+3. **After work**: Update `changelog.md`
+
+### DO NOT
+
+- Add external state libraries (zustand, redux) — use Context + useReducer
+- Add CSS frameworks — use CSS custom properties
+- Duplicate logic from `demo-api.ts` into components

-# Getting Started with EDDI Chat UI
-
-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
-
-## Available Scripts
-
-In the project directory, you can run:
-
-### `npm start`
-
-Runs the app in the development mode.\
-Open `http://localhost:3000/chat/managedbots/:intent/:userId` or `http://localhost:3000/chat/:environment/:botId?userId=:userId` to view it in your browser.
-
-The page will reload when you make changes.\
-You may also see any lint errors in the console.
-
-### `npm test`
-
-Launches the test runner in the interactive watch mode.\
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
-
-### `npm run build`
-
-Builds the app for production to the `build` folder.\
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.\
-Your app is ready to be deployed!
-
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
-
-### `npm run eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can't go back!**
-
-If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
-
-You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.

+
+## Embedding
+
+The chat UI can be embedded in any HTML page via iframe:
+
+```html
+<iframe
+  src="https://your-eddi-server/chat/production/your-agent-id?hideNewConversation=true&theme=dark"
+  style="width: 400px; height: 600px; border: none; border-radius: 12px;"
+></iframe>
+```
+
+## Backend Integration
+
+The production build is deployed into the EDDI Quarkus backend at:
+
+```
+EDDI/src/main/resources/META-INF/resources/
+```
+
+This makes the chat UI available at `http://your-eddi-server/chat.html`.
