WHAT IT DOES

What verse_get_schema does on Uefn

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

RISK

Why verse_get_schema is rated Low

This tool retrieves structural metadata (properties, events, functions) about device classes from digest files. It is purely informational with no side effects, data modification, code execution, or destructive operations. The blast radius of misuse is minimal - an agent could only gather schema information, which is non-sensitive metadata about Verse language structures.

From the tool's definition Tool name contains 'get' and description states 'Get Verse schema...from .digest files' - a retrieval operation with no modification or execution capability.
