Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema) and the annotations covering destructive/read-only/idempotent behavior, the description is fairly complete. It explains what the tool does, the fallback behavior, and the confirmation requirement. It does not describe the return value or post-deletion effects, but with no output schema, that is not required. It also doesn't explain how to obtain the quiz ID, but that is presumably available from other tools (e.g., edubase_get_quiz). Overall, the description is adequate for an agent to invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
