Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool reads text content, but does not disclose behavioral traits such as error handling (e.g., if clipboard is empty), permissions required, or format limitations (e.g., non-text content). This leaves gaps in understanding how the tool behaves in edge cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
