# volume_ramp

Generic volume ramp to a target percent over N minutes (up OR down, step-controlled, optional end-state pause/play) — a superset of schedule_wind_down (which is down-only with floor+pause). Quota: 🟢 stepped PUT /me/player/volume writes (ceil(minutes/step_minutes) calls), in-process, cancel-safe (restart replaces).

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

## Use case

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

## Recommended policy (PolicyLayer)
