ipify_get_ip

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and non-destructive, covering the safety profile. 'Via ipify' usefully signals a third-party network call, but nothing about rate limits, failure modes, or what happens if the upstream service is unreachable.

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?

One short sentence with the purpose front-loaded and zero filler. Nothing to trim.

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 zero-required-param lookup with annotations and a documented schema, the essentials are present. It nonetheless omits the ipv6 option and any sense of the external dependency's behaviour, which is the only thing an agent could get wrong here.

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?

Schema coverage is 100% and the single `ipv6` boolean is fully documented ('Use IPv6 endpoint'), so the schema carries the parameter meaning. The description adds nothing about the flag, which is baseline behaviour when the schema is complete.

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?

States a specific verb and resource: 'Get your public IP address via ipify', which tells the agent exactly what it returns. It does not differentiate from the many siblings doing similar work (httpbin_ip, ip_lookup, ipinfo_lookup, country_by_ip), so an agent can't pick it over those on name alone.

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 choose this over httpbin_ip or ip_lookup, and no mention of when the ipv6 flag matters. The agent is left to guess from the name.

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