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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, and idempotentHint=false, covering the safety profile. The description adds that results are fetched live per URL from an external source (consistent with openWorld) and names the data categories returned, but it omits pagination, rate limits, or what happens when a URL is not indexed.

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 front-loaded sentence that names the source, resource, and payload with no wasted words. Its brevity is efficient, though the same space could have carried sibling-routing guidance.

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?

With no output schema, the description helpfully sketches the returned fields (indexing, crawl info, issues), which is a plus. But for a tool sitting among near-duplicate inspection siblings and requiring a connected site_id, the absence of routing or prerequisite context leaves the definition only minimally adequate.

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%, so both parameters are already documented in the schema, including the meaningful 'concise' vs 'detailed' verbosity toggle. The description adds nothing about either parameter, so the baseline 3 applies.

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 gives a specific verb (inspections) plus resource (URL) and enumerates the returned data: indexing status, crawl info, and issues per URL, sourced from Google Search Console. However, it does not distinguish this tool from close siblings such as inspect_url, batch_inspect, get_index_status, or get_crawl_results, leaving an agent unsure when this is the right 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?

There is no when-to-use guidance, no mention of prerequisites (e.g. site_id must correspond to a connected GSC property), and no reference to alternatives like inspect_url or batch_inspect. The agent must infer the use case purely from the resource name.

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