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, but it offers no information about what the tool does, its effects, permissions, rate limits, or output format. This leaves the agent completely uninformed about how the tool behaves or what to expect from its operation.

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?

While concise with only two words, the description is under-specified and fails to convey essential information. Conciseness should not come at the cost of clarity; here, the brevity results in a lack of useful content, making it inefficient for the agent's understanding.

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?

Given the tool's complexity is unknown but likely involves network data, with no annotations, no output schema, and a minimal description, the description is completely inadequate. It doesn't explain what ISP information is checked, the return values, or any behavioral context, leaving significant gaps for the agent.

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 100% description coverage for its single parameter 'ip', with an example provided. The description adds no additional meaning beyond the schema, but since schema coverage is high, the baseline score is 3, as the schema adequately documents the parameter without needing compensation from the description.

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 'ISP Checker' is a tautology that merely restates the tool name without specifying what action it performs or what resource it operates on. It doesn't indicate whether it checks, retrieves, analyzes, or validates ISP information, nor does it differentiate from sibling tools like 'asn_checker' or 'ip_geolocation_checker' that might handle related IP data.

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. It doesn't mention context, prerequisites, or exclusions, leaving the agent to guess its applicability among many sibling tools that process IPs or domains, such as 'ip_geolocation_checker' or 'whois_domain_lookup'.

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