test_sftp_connection

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of explaining behavior. It merely says 'test', which implies a connection attempt, but it does not disclose what happens on success or failure, whether any state is modified, what permissions are required, or what the response format looks like. This is a significant gap for a tool that could have side effects like network calls or credential validation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, compact sentence that is to the point. It avoids unnecessary verbosity. However, it is so brief that it omits important behavioral details, so while it is concise, it could be slightly more informative without becoming bloated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations and output schema, the description should compensate by explaining the tool's purpose and behavior. It fails to clarify what 'test' means operationally (e.g., does it authenticate, check connectivity, validate credentials?), what the return value represents, or whether specific fields are required for a successful test. The description is incomplete for a tool with five parameters and no structured output information.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with each parameter (host, path, port, password, username) having a short description. The tool description adds no additional meaning beyond the schema. Since the schema already documents the parameters, a baseline of 3 is appropriate; no extra value is provided by the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: 'Test an SFTP connection with the provided credentials'. The verb 'test' is specific and the resource 'SFTP connection' is clear. It distinguishes itself from sibling tools like create_sftp_connection, get_sftp_connection, and delete_sftp_connection, which manage the lifecycle of SFTP connections rather than testing them.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is used to validate SFTP credentials, but it does not explicitly state when to use this tool versus alternatives such as create_sftp_connection or get_sftp_connection. It lacks clear context about prerequisites or exclusions, though the intended use case is reasonably inferable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
