asuswrt_open_ports

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

The description implies a read-only inspection operation but provides no additional behavioral context beyond the basic purpose. With no annotations, the description should offer more details like permissions or side effects, though the tool is simple.

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?

A single sentence of 8 words, starting with the verb, no filler. Every word earns its place.

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 parameterless tool with no output schema, the description sufficiently explains the tool's purpose. However, it could hint at the output format (e.g., list of port/state) to better aid an agent.

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 tool has zero parameters, and schema coverage is 100%. The description adds no param-specific meaning but is not required to. Following the baseline rule for 0 parameters, a score of 4 is appropriate.

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 uses a specific verb 'inspect' and identifies a clear resource 'listening TCP/UDP sockets reported by netstat', distinguishing it from sibling tools that deal with other network aspects like DHCP, ARP, or firewall. No tautology.

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?

No guidance on when to use this tool versus alternatives like asuswrt_network_overview or asuswrt_port_forwarding. No context about prerequisites or typical scenarios.

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