unassign_worker · Baselings MCP: Risk & Policy

WHAT IT DOES

What unassign_worker does on Baselings

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

WHY IT NEEDS A POLICY

Why unassign_worker needs a policy

This tool modifies the state of a worker/baseling by removing their job assignment. This is a reversible write operation (the worker can be reassigned), not destructive. However, misuse could disrupt yield-generating strategies in a financial game context, warranting medium severity.
