Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (one param, no output schema), and annotations cover safety. However, since there is no output schema, the description could clarify what the tool returns (e.g., the password string) or any prerequisites (e.g., SSH must be enabled). It only says 'Get the current SSH/SFTP password', which implies the return value but leaves potential error cases unspecified. For a tool this straightforward, this is a minor gap, so a 3 is appropriate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
