## Example call (MCP tools/call, JSON-RPC 2.0)

## Why get_dom_overview is rated Low

The tool name and context indicate it retrieves DOM structure information. It is part of a UI analysis workflow using Playwright for inspection and diagnostics. No side effects, modifications, code execution, or destructive operations are implied. Although the description is empty, the naming convention and sibling tools strongly suggest this is a Read operation that returns DOM data structure information.

From the tool's own definition: "Tool name 'get_dom_overview' and sibling tools like 'analyze_page', 'get_screenshot', 'get_accessibility_snapshot', 'get_element_details' all follow read-only patterns for web UI inspection."

## Use case

AI agents call get_dom_overview to retrieve information from UI Analyzer MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
