gsc_inspect_url

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

With no annotations provided, the description carries the full burden. It adds a useful note about daily quotas and lists the response dimensions. However, it does not explicitly confirm that the operation is read-only, nor does it mention authorization requirements or potential error conditions. The quota and return-type details provide some coverage, but gaps remain.

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 exactly two sentences: the first states the core purpose and return categories, and the second adds a critical quota warning. It is front-loaded, free of fluff, and every sentence adds value.

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 description is reasonably complete for a read-only inspection tool: it names the key result areas and mentions daily quotas, which is a practical constraint. It lacks an output schema but the description covers the main categories. It could be improved by noting that siteUrl must be a verified property or by clarifying output structure, but overall it is 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?

The input schema already provides 100% coverage with descriptions for each parameter (siteUrl, inspectionUrl, languageCode). The description adds no additional meaning beyond what the schema already states, so the baseline score of 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 clearly states the action ('Inspect a URL') and the resource (Google Search Console), and it enumerates the kinds of data returned (indexing status, crawl info, mobile usability, rich results status). This distinguishes it from sibling tools like gsc_search_analytics or gsc_list_sitemaps, which serve different purposes.

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 usage when you need URL-level inspection data from GSC, but it does not explicitly contrast with alternatives or state when not to use it. There is no mention of using other tools for aggregate analytics or sitemap management, leaving the decision to the agent's inference from sibling names.

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