Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with an output schema, nested options, and one required ID parameter, the description gives enough to call it correctly: what the input artifact provides, what the options affect, and when to omit a parameter. It could go further by noting whether the result is returned directly or saved asynchronously, but the output schema likely covers return behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
