ssh_close_forward

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

No annotations are provided, so the description carries the full burden. It states the action and the return value (confirmation message), but does not disclose potential side effects on the session or any prerequisites beyond the parameter origins.

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, front-loading the purpose, and then efficiently listing arguments and return. Every sentence is necessary and avoids redundancy.

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 tool with two straightforward parameters and an output schema (indicated), the description covers all essential information: what it does, how to get parameters, and what to expect as a result.

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?

With 0% schema description coverage, the description fully compensates by explaining each parameter's provenance: session_id comes from ssh_connect, forward_id from ssh_forward_port. This adds significant meaning beyond the schema's bare type declarations.

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 starts with 'Close a specific port forward,' clearly stating the action (close) and the resource (port forward). This distinguishes it from sibling tools like ssh_forward_port (open) and ssh_close_session (close session).

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 explicitly details how to obtain the required parameters: session_id from ssh_connect and forward_id from ssh_forward_port. This provides clear usage context, but it does not explicitly state when not to use this tool or mention alternatives.

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