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

No annotations provided, so description must disclose behaviors. It does not mention side effects, authentication, rate limits, or whether external calls are made. The read-only nature is implied but not explicit.

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 somewhat cluttered with multiple slash-separated phrases and includes pricing info. It could be more structured and concise, but it still conveys key points.

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?

No output schema and no annotations; the description does not explain the return format or what information is provided (e.g., JSON with classification). This leaves the agent guessing about the tool's output.

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 covers 100% of parameters with basic description. The tool description adds value by listing classification categories (public/private/loopback/link-local/multicast/reserved) and detection capabilities beyond just validation.

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 it validates and classifies IP addresses (IPv4/IPv6) into categories like public/private/loopback, with specific verbs 'validate' and 'classify'. It is distinct from sibling tools that handle Chinese astrology, Feng Shui, or other validations.

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 use this tool versus alternatives. The description lacks context for when IP validation is needed compared to other validation tools like validate_email or validate_url.

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