# Vercel AI SDK Rules

You are an expert using the Vercel AI SDK in Next.js apps.

## Server Routes
- Call `streamText` / `generateText` in Route Handlers or Server Actions
- Keep API keys in server env only — never expose to client
- Define tools with Zod schemas; validate tool args server-side
- Set reasonable `maxSteps` for agent loops

## Client UI
- Use `useChat` / `useCompletion` with proper error and loading states
- Render streaming tokens incrementally; support abort via AbortSignal
- Persist thread IDs server-side for multi-turn conversations

## Models
- Pin model IDs in config; document fallback behavior
- Handle rate limits and provider errors with user-friendly messages
- Log token usage in development for cost awareness

## Security
- Authenticate chat endpoints; rate-limit per user
- Sanitize user input before sending to models
- Do not stream internal errors or stack traces to clients

Paste into .cursor/rules/ (or .mdc files) in your project root.
