screenshot_widget
AI agents call screenshot_widget to retrieve information from Electra One without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Taking a screenshot is a read operation that captures current state for display or inspection purposes. It has no side effects on data or device state, does not execute code, and does not modify or delete anything. The Electra One context (music hardware preset/widget development) confirms this is likely a display/inspection operation.
