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 and no output schema, the description is inadequate. It doesn't explain what happens on success/failure, return values, error conditions, or important behavioral constraints. Given 3 parameters (including a nested object) and the creation nature, more context about permissions, idempotency, and response format is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
