ssh_disconnect

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

With no annotations, the description must carry the full burden. It mentions 'cleanly close' but doesn't disclose side effects like what happens to associated sessions, idempotency, or error behavior. It's minimally adequate but not rich.

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 short and includes a practical JSON example, which helps the agent. It repeats the concept slightly ('Disconnect' and 'close SSH connections'), but overall it's well-structured and efficient.

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?

For a simple one-parameter tool with no output schema, the description is adequate. It provides an example and clear use case. It doesn't cover errors or edge cases, but given the low complexity, this is not a significant gap.

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 coverage is 100% with the parameter described as 'ID of the SSH connection to disconnect'. The example usage adds an illustrative value (raspberry-pi) but doesn't add semantic meaning beyond the schema, so baseline 3 applies.

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 verb 'Disconnect' and the resource 'SSH connection/server', which distinguishes it from siblings like ssh_execute and execute_command. The example usage reinforces the exact action.

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?

It says 'when they're no longer needed', providing clear context for when to use this tool. It doesn't explicitly mention alternatives or when not to use, but the sibling tool names imply the distinction, so a slight deduction is warranted.

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