Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations, no output schema, zero schema description coverage, and a required identifier, the description is not complete enough. An agent cannot tell how to identify the workshop beyond guessing at workshop_id, what permissions are needed, or what the result of a successful update looks like.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
