What remove_simpler_slice does on Livepilot
AI agents call remove_simpler_slice to permanently remove resources in Livepilot, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why remove_simpler_slice is rated Critical
The tool removes (irreversibly deletes) a slice from a Simpler instrument at a specific sample-frame position. This is a destructive action as removing a slice cannot be trivially undone programmatically, though Ableton's undo history may allow manual recovery. Blast radius is medium as it affects a single slice within a single instrument device.

The rule that runs remove_simpler_slice safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Livepilot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For remove_simpler_slice, this is the rule to start with:
remove_simpler_slice is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Livepilot, apply this rule, and every remove_simpler_slice call is checked against it from then on.
