WHAT IT DOES

What task_create does on Claude Flow

AI agents use task_create to create or update resources in Claude Flow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Flow environment.

WHY IT NEEDS A POLICY

Why task_create needs a policy

This tool creates and persists new data (tasks) in a database, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, move money, or read without side effects.

From the tool's definition Tool name 'task_create' and description explicitly states 'Create a new task' with persistent storage to '.swarm/memory.db', modifying a task database. The tool creates new records reversibly (tasks can be deleted or updated later).
