WHAT IT DOES

What cancel_task does on Pengstrike

AI agents call cancel_task to permanently remove resources in Pengstrike, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why cancel_task is rated Critical

An AI agent that decides to call cancel_task doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Pengstrike is gone. There is no undo for destructive operations.

RECOMMENDED RULE

The rule that runs cancel_task safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pengstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cancel_task, this is the rule to start with:

cancel_task Hidden

cancel_task is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
