Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (7-stage pipeline, registration side effects, multiple parameters), the description is complete: it covers the validation process, success/failure outcomes, promotion path, parameter semantics, and return schema. The only mild gap, alternative tool selection, is already covered under usage guidelines. An agent has enough context to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
