AI agents call capture_full_scrollable_page to retrieve information from InSite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves visual content from a webpage by taking a screenshot. It has no side effects—it does not modify page state, execute scripts, delete data, or trigger external operations. The action is purely observational and reversible. It falls squarely into the Read category as a data retrieval operation.
