classify_ip

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

No annotations exist, so the description must fully convey behavioral traits. It states it classifies by 'scope and allocation type' but does not disclose possible output values, format, or any side effects. The agent cannot infer the classification categories or return structure.

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 sentence, which is concise and front-loads the purpose. However, it is overly brief, sacrificing necessary details for the sake of brevity.

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?

The tool is simple (one parameter) but the description is incomplete. It does not explain what 'scope and allocation type' means, list possible outputs, or relate to sibling tools. An agent cannot reliably invoke this tool without additional context.

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 0%, requiring the description to explain the parameter. However, it only mentions 'IPv4 address' generically, not specifying the format (e.g., dotted decimal) or constraints. The parameter name 'ip' and title 'Ip' offer no additional meaning.

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 tool's purpose: classifying an IPv4 address by scope and allocation type. The verb 'classify' and resource 'IPv4 address' are specific, and the tool is distinct from its sibling tools (e.g., check_coverage, cidr_to_range) which perform different operations.

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 is provided on when to use this tool versus alternatives, such as checking coverage or converting IPs. The description lacks context about prerequisites, limitations, or exclusion criteria.

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