-            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
-
-            STEP 1: Check existing comments to avoid duplicates.
-            Run: `gh api repos/${{ github.repository }}/pulls/${{ github.event.pull_request.number }}/comments`
-
-            Build a list of files and line numbers that already have comments. For each existing comment:
-            - If the issue is FIXED in current code, resolve the thread using:
-              `gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "THREAD_ID"}) { thread { isResolved } } }'`
-            - If the issue still exists, remember this file:line - DO NOT create a new comment for it
-
-            STEP 2: Review the diff for issues, but SKIP any file:line that already has a comment.
-
-            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:
-            - NEVER create a comment on a file:line that already has a comment - this causes duplicates
-            - For each NEW issue, use `mcp__github_inline_comment__create_inline_comment` to comment on the specific line
-            - ALWAYS include a suggested fix using GitHub's suggestion syntax: ```suggestion\n<fixed code>\n```
-            - Only say "LGTM" if there are truly ZERO new issues to report
