Implementation Reference
- src/index.ts:597-661 (handler)Handler for 'update_task' tool call. Constructs and executes a Python script that creates a TaskUpdate object with the provided parameters (duid required, others optional), wraps it in an UPDATE Operation for TASK model, and submits via client.transact with TASK_UPDATE transaction kind.
