Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (destructive, 2 params, output schema), the description fully covers all necessary aspects: purpose, behavior, parameters, and return value. It also addresses an edge case (omitting show_name) and references the manual, making it complete for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
