gsc_page_performance

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

No annotations are provided, so the description carries the full disclosure burden, yet it says nothing about authentication against the verified property, row limits, date-range constraints, or result volume. It does imply the shape of the output (daily series plus top queries), which is the only behavioral hint present.

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 with no filler; every clause carries content. It is appropriately sized, though it is too terse to be exemplary.

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 annotations and no output schema, the description should carry more weight, but the fully documented input schema offsets the parameter gap. It hints at return contents without specifying date-range limits or result 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 100% and all four parameters are documented in the schema with format and pattern detail, so the baseline is 3. The description adds only the notion that the url must be an exact page, which the schema already conveys.

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 names a specific resource (una página exacta) and the data returned (serie diaria y consultas principales) inside Google Search Console, so an agent knows exactly what it fetches. It does not, however, explicitly distinguish itself from siblings like gsc_search_performance or gsc_query_advanced.

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 prerequisites and no mention of the alternative tools for site-wide or query-level reporting. The only signal is the implicit inference that this is the per-page variant.

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