Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly states the tool lists all available templates, indicating a read-only operation with no filtering. It does not mention potential nuances like archived templates or pagination, but given the simplicity of the operation, the core behavior is transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
