Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple status poll with 1 parameter and no output schema, the description covers purpose, deployment context, and return fields. However, it lacks detail on the format of progress metadata, possible error states, or how the 'degrades to info' behavior manifests. Given the simplicity, it is mostly adequate but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
