Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses a specific behavioral trait: Blender appends .001 if the name is taken. However, with no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention the optional rename_data parameter or its effect on the data block, nor any side effects, reversibility, or permissions. This is limited transparency beyond the single conflict-resolution detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
