Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter GET tool with a clear sibling (oauth2_clients_list), the description is mostly adequate. However, with no annotations and no output schema, there's no mention of what details are returned (scopes, redirect URIs, client secret, status, etc.) or whether the result includes sensitive fields. For such a lightweight tool, this is adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
