ssh_close_session

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

With no annotations, the description provides critical behavioral context: it kills running processes and releases all resources. The warning about processes is explicitly stated. However, it does not describe whether the operation is synchronous or if there are any side effects beyond what is mentioned.

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 brief and front-loaded: the first sentence states the main purpose, followed by a warning, then the parameter description. Every sentence adds value with no redundancy. It is well-structured for an AI agent to quickly understand.

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 simplicity of the tool (one parameter, no nested objects), the description covers key aspects: what it does, what it releases, the warning, the parameter source, and the return type. Output schema exists but is not shown; the description mentions a confirmation message. It feels complete for effective use.

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?

The only parameter, session_id, is described as 'The session ID returned by ssh_connect,' which adds valuable context beyond the schema's data type. Since schema coverage is 0%, this description compensates well. No other parameters exist.

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 closes an SSH session and releases all resources, including shell, SFTP, and port forwards. It distinguishes from siblings like ssh_close_forward by specifying it closes the session itself. The warning about killing processes adds further specificity.

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 does not explicitly state when to use this tool versus alternatives, though the context from sibling names makes it somewhat clear. It lacks explicit exclusions or guidance on prerequisites. However, the purpose is evident from the name.

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