Locate IP Addresses

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

With no annotations, the description must disclose behavioral traits. It mentions the limit of 10 IPs and the return fields, which is helpful. However, it does not mention potential edge cases (e.g., invalid IPs), read-only nature, or any side effects. The transparency is adequate but not comprehensive.

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 a single, concise sentence that front-loads the action and resource. It includes key output details without unnecessary elaboration. Every word contributes to understanding.

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 one-parameter lookup tool, the description adequately explains the input and output. It has no output schema but lists the geolocation fields, which satisfies the need to know return values. However, it lacks usage guidance and error handling details, preventing a perfect score.

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 schema already fully describes the only parameter (ipAddresses) with high coverage, so the baseline is 3. The description repeats the 'up to 10' limit but adds no additional meaning beyond the schema, such as IP format or error behavior.

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 the tool locates up to 10 IP addresses and returns geolocation data with specific fields (city, country, region, ASN, network). This is a specific verb+resource pairing that distinguishes it from sibling tools like verify_locate_ip, which likely focuses on verification rather than location lookup.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention exclusions or prerequisites. It simply states what the tool does without contextualizing its use cases relative to the sibling tools.

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