+export const REPLACEMENT_MESSAGE = `TodoRead/TodoWrite are DISABLED because experimental.task_system is enabled.
+
+**ACTION REQUIRED**: RE-REGISTER what you were about to write as Todo using Task tools NOW. Then ASSIGN yourself and START WORKING immediately.
+
+**Use these tools instead:**
+- TaskCreate: Create new task with auto-generated ID
+- TaskUpdate: Update status, assign owner, add dependencies
 - TaskList: List active tasks with dependency info
 - TaskGet: Get full task details
 
-IMPORTANT: 1 task = 1 delegate_task. Maximize parallel execution by running independent tasks concurrently.`
+**Workflow:**
+1. TaskCreate({ subject: "your task description" })
+2. TaskUpdate({ id: "T-xxx", status: "in_progress", owner: "your-thread-id" })
+3. DO THE WORK
+4. TaskUpdate({ id: "T-xxx", status: "completed" })
+
+CRITICAL: 1 task = 1 delegate_task. Fire independent tasks concurrently.
+
+DO NOT retry TodoWrite. Convert to TaskCreate NOW.`
