Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter delete operation with strong annotations and an explicit description, this is largely complete. It covers the action, the trigger, and related tools. The lack of an output schema is compensated by the straightforward nature of the operation, though it never states what happens after deletion (e.g., success confirmation).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
