Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'create' implies a write operation, it doesn't specify permissions required, whether the operation is atomic/transactional, how failures are handled in batch, or what the response format looks like. For a batch mutation tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
