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

With no annotations provided, the description carries the full burden. It successfully discloses the return payload categories (country, city, coordinates, network info) but omits other behavioral traits like rate limits, error handling for invalid IPs, or data freshness. For a simple lookup tool, this is minimally adequate.

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?

Single sentence, front-loaded with the verb, includes input type, output specification, and provider attribution ('Geoapify') with zero redundant words. Excellent information density.

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 single-parameter tool with complete schema coverage, the description adequately compensates for the missing output schema by enumerating the return data categories. It successfully conveys the tool's utility despite lacking formal output schema documentation.

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 description coverage is 100%, providing detailed parameter documentation including examples ('8.8.8.8'). The description mentions 'IPv4/IPv6' which aligns with the schema but adds no additional semantic context (validation rules, format requirements) beyond what's already specified in the structured schema.

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 action ('Geolocate'), input ('IP address'), and specific output fields ('country, city, coordinates, and network info'). It distinguishes itself as a geolocation-specific tool (vs. generic IP intelligence) by listing geographic output fields, though it doesn't explicitly differentiate from siblings like 'ip.intelligence.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?

No explicit when-to-use guidance or alternatives are mentioned. Given siblings like 'ip.intelligence.lookup' and 'security.ipqs.ip_check' also handle IP data, the description should clarify that this tool is specifically for geographic location data rather than threat intelligence or general IP metadata.

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