Thread, Streaming & Markdown Capabilities +- **Thread Experience**: + - Virtualized auto-scrolling message list with smooth pin-to-bottom behavior. + - Multi-turn conversation display with branch switching (edit previous user prompt & view alternative branches). + - Suggested starter prompt pills on empty thread state. +- **Streaming Markdown & Code Blocks**: + - Handled via `@assistant-ui/react-markdown` and `@assistant-ui/react-syntax-highlighter`. + - Syntax highlighting for 50+ programming languages. + - Copy code button with confirmation feedback. +- **Message Actions**: + - Stop generation button (AbortController). + - Reload / Regenerate button. + - Copy message text / markdown. + +### 4.3. Generative UI & Tool Calling +Integrate custom tool renderers inside `assistant-ui`'s `` / `makeAssistantToolUI`: +1. **`searchDocumentation`**: + - Searches Nextra docs and sitemap. + - Renders interactive HeroUI card with document title, excerpt snippet, and direct link navigation. +2. **`setTheme`**: + - Switches active theme (`light`, `dark`, `system`) on the client and renders a theme switch status pill. +3. **`getSystemInfo`**: + - Queries stack metadata (Next.js 16, React 19, HeroUI v3, Tailwind v4) and reports environment status. +4. **`navigatePage`**: + - Renders confirmation card with a button to navigate to target route. + +### 4.4. Input, Speech & Persistence +- **Composer**: + - Auto-growing multiline textarea with `Enter` (send) and `Shift + Enter` (newline). + - Integrated speech-to-text voice input button using Web Speech API with fallback. +- **Local Persistence**: + - Chat history preserved across page reloads via `localStorage` integration. + +### 4.5. Multi-Provider & Zero-Config Fallback +- **Environment Driven Provider**: + - `AI_PROVIDER`: `"mock"` (default) | `"google"` | `"openai"` | `"anthropic"` | `"custom"`. + - `AI_MODEL`: Specific model identifier (e.g. `gemini-2.5-flash`, `gpt-4o-mini`, `claude-3-7-sonnet`). + - `GOOGLE_GENERATIVE_AI_API_KEY`, `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `AI_BASE_URL`. +- **Zero-Config Mock Provider**: + - When no API key is present or `AI_PROVIDER="mock"`, realistic streaming responses and mock tool calls are simulated. + +--- + +## 5.

TypeScript & Code Quality +- Strict TypeScript (`"strict": true`), zero `any` types. +- Explicit interfaces for all custom tool components and hook parameters. +- Co-located component structure under `app/components/AIAssistant/`. + +### 5.2. Accessibility & Performance +- Full keyboard operability and focus management provided by `@assistant-ui/react` primitives. +- ARIA live region announcements for streaming message updates. +- Axe-core accessibility clean (zero WCAG violations). + +### 5.3. Testing Strategy +- **Vitest Unit Tests ($\ge 80\%$ coverage)**: + - `app/api/chat/route.test.ts` (API route streaming, error handling, mock fallback). + - `app/components/AIAssistant/index.test.tsx` (Assistant trigger, modal state, tool card rendering). + - `app/lib/ai/tools.test.ts` (Tool schemas & execution). +- **Playwright E2E Tests**: + - End-to-end verification of opening modal, submitting prompt, streaming mock response, and running axe-core a11y audit. + +--- + +## 6.
