gsc_bulk_inspect_urls

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

Beyond the annotations (read-only, idempotent, non-destructive), the description discloses two meaningful behavioral traits: concurrency limiting ('bounded concurrency') and per-URL error handling ('partial failures are returned per URL'). This adds value without contradicting the annotations.

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 conveys the core action and key operational behavior. Every word contributes meaning without unnecessary verbosity.

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 moderate complexity (4 parameters, no output schema) and low schema coverage, the description is too sparse. It does not explain what the inspection results look like, the maximum URL count, the meaning of 'partial failures', or any usage prerequisites. The mention of partial failures is helpful but incomplete without clarifying the response structure.

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 only 25% (only siteUrl has an inline description). The tool description provides no parameter-level detail about concurrency limits, languageCode, or inspectionUrls format. It only alludes to 'multiple URLs', which overlaps with inspectionUrls. With low schema coverage, the description fails to compensate for the missing parameter semantics.

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 function: 'Inspect multiple URLs' with a specific distinctive feature ('bounded concurrency'). It distinguishes itself from the sibling gsc_inspect_url by explicitly targeting multiple URLs rather than a single one.

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 implies a batch use case ('multiple URLs') but does not explicitly contrast with alternatives like gsc_inspect_url for single-URL inspection. It mentions bounded concurrency and partial failures, which hint at operational context, but lacks clear 'when to use / when not to use' guidance.

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