ssh_list_forwards

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

No annotations provided, so description carries full burden. It discloses that the tool lists active port forwards (read-only) and returns a list of forward info dicts. This is sufficient behavioral context for a simple listing operation.

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 extremely concise: one sentence for purpose, plus structured Args/Returns. Every sentence adds value with no waste.

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 tool's simplicity (one parameter, output schema exists), the description adequately covers what it does, its input, and output. Sibling differentiation is clear from context. A small gap: no mention of error conditions (e.g., invalid session).

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?

Even though schema description coverage is 0%, the description adds meaning beyond the schema by explaining session_id as 'The session ID returned by ssh_connect', clarifying its origin and necessity.

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 'List all active port forwards for an SSH session', using a specific verb ('list') and resource ('active port forwards'). It distinguishes from sibling tools like ssh_forward_port (creates forwards) and ssh_close_forward (closes forwards).

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 usage after ssh_connect (references session_id), but does not provide explicit when-to-use or when-not-to-use guidance nor alternatives. The usage context is clear enough for an experienced agent.

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