WHAT IT DOES

What karea_doing does on Karea

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

WHY IT NEEDS A POLICY

Why karea_doing needs a policy

This tool creates a new task entity in reversible manner—the task can be edited or closed later. It modifies the task management system by adding a new record, but does not execute external code, delete data, or have financial implications. The blast radius is minimal as the operation is confined to task creation within the system and poses low risk if invoked incorrectly by an agent.

From the tool's definition Tool description states 'Create a task' which creates a new record with status 'in_progress'. The word 'Create' indicates data creation rather than retrieval, deletion, or code execution.
