Capture simulator screenshot
AI agents call simulator_screenshot to retrieve information from Xclaude Plugin 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 passive observation action with no side effects, data modifications, or external operations triggered. It merely captures and returns the current visual state of the simulator. This aligns with the Read category definition of retrieving data with no side effects. Severity is low because screenshot capture poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'simulator_screenshot' and description 'Capture simulator screenshot' indicate a read-only operation that retrieves visual state of a running iOS simulator without modifying any data or state.
