WHAT IT DOES

What get_activity_message does on Huly

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

RISK

Why get_activity_message is rated Low

This tool retrieves data by ID lookup. The verb 'Get' combined with the retrieval-only semantics (returning metadata without creating, modifying, or deleting anything) clearly places it in the Read category. The severity is low because querying existing data poses minimal risk to systems or data integrity.

From the tool's definition Tool name is 'get_activity_message' and description states it 'Get[s] a single activity message by ID', which is a retrieval operation with no modification or side effects.

get_activity_message Allowed
