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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what data is collected, but does not describe permissions, rate limits, whether active port/vulnerability scanning may trigger alerts, or what the response contains. The feature list is useful context but falls short of required behavioral transparency.

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 with no filler. It efficiently communicates the tool's feature set without wasting space. Every element earns its place, though the terseness contributes to gaps in other dimensions.

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 a fairly complex aggregator with an undocumented parameter, no annotations, and no parameter description. While an output schema exists and reduces the need to explain return values, the description still omits essential calling information: what 'q' expects and when to use this over similar IP tools. It is insufficiently complete for an agent to invoke it reliably.

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 schema has one parameter, 'q', with no description and 0% schema coverage. The tool description never mentions 'q' or explains that it should receive an IP address. An agent must guess the parameter's meaning from the tool name alone.

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 names a specific resource ('IP Deep Intel') and enumerates the data types it aggregates: Geo, ASN, VPN/proxy/Tor risk, open ports/vulns, and reverse DNS. This distinguishes it from narrower siblings like ipgeo or ipint. It lacks an explicit verb and does not state the required input, but the purpose is clear enough.

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 lists features but gives no guidance on when to choose this tool over alternatives such as ipfull, ipgeo, ipint, or ipwhois. There is no mention of prerequisites, exclusions, or the conditions under which a deep lookup is appropriate. Usage must be inferred entirely by the agent.

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