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

No annotations are provided, so the description carries full burden. It accurately states the tool classifies IP addresses with no side effects, implying a safe read-only operation. No contradictions or hidden behaviors are suggested.

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, efficient sentence that concisely conveys purpose, classification categories, and use case without unnecessary words.

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 classification tool with one parameter and no output schema, the description is reasonably complete. It lists the classification categories and hints at the SSRF use case, though it does not describe the output format or error handling.

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 input schema has 0% coverage and a single parameter 'ip' with no description. The tool name implies IPv4, and the description lists classification categories, but it does not explicitly specify parameter format, validation, or acceptable values.

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 specifies a clear verb 'Classify' and resource 'IP' with explicit categories (private/loopback/link-local/global) and the use case 'SSRF helper', distinguishing it from sibling tools like ip_version_detect or geolocation.

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 context (SSRF helper) but does not explicitly state when to use or avoid this tool versus alternatives. No exclusion criteria are mentioned.

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