+
+            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
+
+            First, check previous review comments from github-actions bot using `gh api repos/${{ github.repository }}/pulls/${{ github.event.pull_request.number }}/comments`.
+            For each previous comment:
+            - If the issue is fixed in the current code, resolve the comment thread using:
+              `gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "THREAD_ID"}) { thread { isResolved } } }'`
+              Get the thread ID from the comment's node_id field.
+            - If the issue still exists, leave it alone
+
+            Then review the current diff for NEW issues only:
+
+            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.
+            Key doc pages: /docs/ai-sdk-ui/chatbot, /docs/ai-sdk-core/generating-text, /docs/ai-sdk-core/tools-and-tool-calling
+
+            DO NOT comment on:
+            - Performance optimizations
+            - Code style or formatting
+            - "Best practices" that don't affect functionality
+            - Type safety improvements
+            - Error handling additions
+
+            Use `mcp__github_inline_comment__create_inline_comment` for inline comments.
+            Be very selective - if there are no real bugs, just say "LGTM" in a PR comment.
