list_ip

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the HTTP method and path (GET /ip), which is consistent with the annotations and provides small extra context, but it does not explain the response semantics or whether this exposes the server's or client's IP.

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 appropriately tiny for a zero-parameter, read-only endpoint and is front-loaded with the core action. Both lines ('Get IP.' and 'GET /ip') earn their place, though it is close to being under-specified rather than efficiently concise.

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 trivial zero-parameter read with an output schema and strong safety annotations, the description covers the essentials. However, it fails to disambiguate what 'IP' refers to and gives no hint about how this differs from similar IP-related sibling tools, which is a real gap for agent selection.

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 0 parameters and schema coverage is trivially complete, so the baseline of 4 applies. There is nothing for the description to clarify regarding parameters, and it correctly avoids inventing unnecessary detail.

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?

"Get IP" states a verb and resource and the endpoint "GET /ip" confirms it, so it is not a tautology. However, it is so terse that it leaves ambiguity about whose IP is returned and does not distinguish itself from the adjacent list_geoip or list_identity utilities among the siblings.

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?

There is no guidance about when to use this tool versus alternatives such as list_geoip, list_ping, or list_identity. The description provides neither a condition for selecting this tool nor any exclusions, leaving the agent to guess based on the name alone.

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