Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description provides minimal behavioral information beyond the basic operation. Given no annotations, it should disclose what happens if the charge ID does not exist (e.g., returns null vs error), whether the operation is read-only, and any permission requirements. It only states 'Get', leaving important behavior undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
