AI agents call ax_read_table to retrieve information from MacWright without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries table/outline view data from macOS applications. It performs no modifications, deletions, or external operations. The read-only nature and limited scope to native UI data access make it a straightforward Read category tool with low severity.
From the tool's definition Tool description states 'Read row data from a native macOS AX table' - the verb 'read' and absence of modification language clearly indicate data retrieval without side effects.
