Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the burden of behavioral disclosure. It reveals that the tool reads from a local directory (~/.ae-mcp/blender-exchange/) and 'List' implies a read-only operation, but it does not explicitly state side-effect-free behavior or what happens if the directory is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
