geolocate_ip

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does disclose the payment cost, which is useful, but it omits important behavioral traits such as network usage, authorization requirements, return behavior, and potential errors. The core behavior is left implicit in the tool name.

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 front-loaded, but the opening phrase merely repeats the tool name and the 'Data & Weather tool' label adds little value. The cost information is concrete and earns its place, so the conciseness is acceptable but under-specified.

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?

With no output schema and no annotations, the description should provide more complete context. It omits expected return format, input syntax, and usage boundaries, making it difficult for an agent to confidently invoke the tool or interpret its results.

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 input schema exposes only a generic 'params' object with no meaningful field definitions, and the description adds no explicit parameter semantics. The tool name implies the parameter is an IP address, but there is no clarification of IPv4 vs IPv6, required fields, or optional parameters.

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 mostly restates the tool name ('geolocate ip') and labels it as a 'Data & Weather tool' without specifying its actual operation. It fails to clearly state that this tool performs IP address geolocation or what kind of output it returns, and it does not distinguish it from sibling tools like geocode or reverse_geocode.

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 explicit guidance is given about when to use this tool versus alternatives. The only usage-related detail is the cost and payment method ($0.001 USDC via x402), but there is no mention of when IP geolocation is appropriate or when a different tool should be used instead.

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