bgpview_ip

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

Annotations already declare readOnly, idempotent, openWorld, non-destructive, so the safety profile is fully covered structurally. The description adds the useful detail of what data categories come back (PTR, prefix, ASN) in the absence of an output schema, but says nothing about rate limits, upstream failures, or response shape.

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?

A single front-loaded sentence naming verb, resource, returned fields, and upstream source, with no filler.

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 read-only lookup whose annotations cover safety and whose only input is fully documented, the description is nearly sufficient. The minor gap is the absence of IPv4/IPv6 or error-behavior detail, which matters slightly for an external API wrapper.

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?

One parameter with 100% schema description coverage, so the schema carries the semantics. The description adds no format constraints (IPv4 vs IPv6), no prefix-length or CIDR guidance, so the baseline 3 is appropriate.

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 (look up) and resource (IP address details), and enumerates the returned data classes (PTR, prefix, ASN), which distinguishes it from the sibling ASN/prefixed-focused tools. It does not explicitly name the alternative lookups (ipinfo_lookup, rdap_ip, bgpview_asn), so not a 5.

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 statement of when to use this versus ipinfo_lookup, rdap_ip, ip_lookup, or bgpview_asn. The only guidance is implicit in the tool name and the word 'look up'.

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