WHAT IT DOES

What memento_toggle_superpowers does on Memento

AI agents invoke memento_toggle_superpowers to trigger actions in Memento. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why memento_toggle_superpowers needs a policy

Toggling agentic superpowers changes the operational mode of an autonomous AI system, enabling or disabling proactive/autonomous behaviors that can trigger external operations and auto-generate tasks. This is an Execute-level action because it governs whether the agent autonomously acts in the environment. Severity is high due to the blast radius of enabling unconstrained autonomous agent behaviors.

From the tool's definition 'Toggle Memento Agentic Superpowers (Proactive Warnings and Auto-Generative Tasks)' — enables or disables autonomous agent behaviors including proactive warnings and auto-generative tasks
