Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the burden of disclosing behavior. It details what detections are included and that the enterprise dimension scans specific frameworks via 'MEGA MCP oracles', adding useful behavioral context. However, it does not state whether the operation is read-only, potential performance implications, or any side effects, leaving gaps for a non-annotated tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
