AI agents call check_grammar to retrieve information from BeLikeNative Grammar Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It is purely analytical with no side effects, fitting the Read category. Severity is low because misuse would at worst provide incorrect grammatical feedback with no destructive, financial, or operational consequences.
