cidr_shield_lookup

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

No annotations are provided, so the description carries the full behavioral burden. It discloses the detection categories and a latency claim, but omits authentication requirements, rate limits, and what the response actually looks like, leaving meaningful behavioral gaps for a lookup service.

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, front-loaded sentence that states the input, performance claim, and detection scope 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 single-parameter lookup tool with no annotations and no output schema, the description covers the input and detection categories but does not describe the return format or result semantics. The agent knows what to pass but not exactly what structure to expect back.

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%, and the single parameter is fully documented in the schema with the same IPv4 example format provided in the description. The description adds no syntax or semantic detail beyond the schema, so the baseline of 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?

The description states a specific verb ('Query') and resource ('IPv4 address') and explains what the query detects: Datacenter/Cloud servers, VPNs, Tor, and bot proxies. The function is immediately clear, and the sibling tools are unrelated, so no further differentiation is needed.

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 detection categories imply the tool's use case (IP intelligence / proxy detection), but there is no explicit guidance on when to use it versus alternatives or any exclusions. This is adequate implied usage, not explicit routing advice.

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