What crow_media_search does on Crow
AI agents call crow_media_search to retrieve information from Crow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why crow_media_search is rated Low
This tool retrieves and queries data without side effects. The discover_sources parameter adds web searching capability, but this remains a read operation that fetches information rather than modifying, executing, or destructively acting upon data. The blast radius of misuse is minimal—an AI agent could retrieve unwanted articles or RSS feeds, but no persistent harm or data loss would occur.
From the tool's definition Tool performs 'full-text search across articles' and optionally searches 'the web for new RSS feeds' — both read-only query operations with no modification, deletion, or execution of code.
