AI agents call scout_search_posts to retrieve information from Scout without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing posts without creating, modifying, deleting, or executing external operations. While it operates within a browser automation context (Scout), the specific action is purely informational retrieval. The low severity reflects minimal blast radius—searching posts cannot cause unintended data loss, financial harm, or system compromise. Confidence is high due to clear read-only semantics.
From the tool's definition Tool name 'scout_search_posts' and description 'Search for posts on a platform' indicate data retrieval with no modification or deletion. The verb 'search' is explicitly a read operation.
