Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one integer parameter, no output schema, destructive action), the description is nearly complete. It covers the action, the side effect (clients deletion), and irreversibility. It doesn't mention error handling (e.g., behavior if ID doesn't exist), but that information is often not necessary for a deletion tool, and the annotations (idempotentHint) hint at behavior for repeats. Overall, the essential context is present.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
