Batch Url Inspection

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

Annotations are absent, so the description carries full burden. It states the tool 'inspects' which implies a read-only operation but does not explicitly confirm non-destructive behavior. It also doesn't mention any rate limits, authentication requirements, or error handling for invalid URLs. Minimal transparency beyond the basic action.

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?

A single, efficient sentence with no redundant words. It front-loads the action and lists key inspection dimensions in a compact list.

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 has an output schema and fully documented parameters, the description covers the basic action. However, it omits any guidance on when to choose this over the sibling inspect_url, and it does not state the max URL limit (though that's in the schema). For a batch tool, some context about expected use cases would improve completeness.

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 coverage is 100% for both parameters ('urls' and 'site_url'), and the schema descriptions are clear. The tool description adds little beyond restating that it inspects multiple URLs, which is already implied by the parameter name 'urls'. With high schema coverage, the baseline is 3; no additional meaning is provided.

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 ('inspect'), a resource ('multiple URLs'), and specific inspection dimensions (indexing status, mobile usability, rich results). It clearly implies a batch operation distinct from the single-URL sibling 'inspect_url', though it doesn't explicitly name the alternative.

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 no guidance on when to use this tool versus the single-URL inspect_url alternative. It does not mention that inspect_url is for individual URLs or that batch_url_inspection is for bulk checks. No explicit context for selection is given.

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