2. js_code must be exactly: async function workflow(input) with proper MCP calls
3. Input schema: documentPath, outputPath, analysisType (all required strings)
4. Use exact mcp.call() format for each workflow step
5. Include comprehensive error handling with try/catch blocks
6. Return structured success/error responses

Expected JSON:

    "type": "object",
    "properties": {
