AI agents call compare_versions to retrieve information from Fichapao without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool compares two recipe versions and reports changed fields. This is a purely informational, read-only operation with no data modification, execution, or destructive capability. Misuse risk is minimal.
From the tool's definition Compara duas versoes da ficha e indica campos alterados — 'compara' (compares) and 'indica' (indicates) describe a read/query operation with no side effects
