            This is a personal project - an AI-powered draw.io diagram generator built with:
            - Next.js 15 with React 19
            - Vercel AI SDK (streamText, useChat, tool calling)
            - Multiple AI providers: Bedrock, Anthropic, OpenAI, Google, Azure, OpenRouter, Ollama

            Review this PR for ONLY these issues:
            1. Bugs that would cause runtime errors or broken functionality
            2. Security issues (exposed secrets, API key leaks)
            3. AI SDK misuse - specifically check for:
               - Client-side: Should use useChat/useCompletion/useObject hooks, NOT raw fetch()
               - Server-side: Should use streamText/generateText/streamObject/generateObject
               - Message handling: Access message.parts array, not legacy content property
               - Tool definitions: Must use Zod schemas for inputSchema
               - Status handling: Check status (submitted/streaming/ready/error) before actions
               - Stream cleanup: Call stop() when aborting streams

            When reviewing AI SDK usage, fetch https://ai-sdk.dev/docs/ to verify correct patterns.

            DO NOT comment on:
            - Performance optimizations
            - Code style or formatting
            - "Best practices" that don't affect functionality
            - Type safety improvements
            - Error handling additions

            Be very selective - if there are no real bugs, just say "LGTM" in a PR comment.
