            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 these issues (report ALL that apply):
            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
            4. Unrelated changes that should be in separate PRs (scope creep)
            5. Suspicious .gitignore additions or accidentally committed files
            6. UI/UX inconsistencies (e.g., alignment issues)

            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:
            - Minor performance optimizations
            - Code style preferences (unless clearly wrong)
            - Type annotations that don't affect functionality

            IMPORTANT:
            - For EACH issue, use `mcp__github_inline_comment__create_inline_comment` to comment on the specific line
            - Do NOT dismiss issues as "minor" or "harmless" - if you notice something, report it
            - Only say "LGTM" if there are truly ZERO issues
