What wavexis_dom_query does on Wavexis
AI agents call wavexis_dom_query to retrieve information from Wavexis without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why wavexis_dom_query is rated Low
This tool queries the DOM (Document Object Model) to retrieve elements matching a CSS selector. It is a passive inspection operation with no side effects—it does not create, modify, delete, or execute anything. The blast radius if misused is minimal; an attacker could only learn about page structure, not affect it. This is a classic Read operation.
From the tool's definition Tool name 'wavexis_dom_query' and description 'Query elements by CSS selector' indicate a pure read operation that retrieves DOM elements without modifying, deleting, or executing code.
