ga4_top_pages

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

No annotations are provided, so the description carries the full burden of disclosing behavioral traits. It only states what the tool returns (top pages by page views) but gives no information about authorization needs, rate limits, data freshness, or any side effects. For a read-only report tool, this is a notable gap.

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 two sentences and gets straight to the point. 'A convenient shortcut for a common report' adds practical context without waste. No redundancy or fluff.

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 tool is simple, all parameters are documented, and the description clarifies the report type. There is no output schema, so the description could have elaborated on the returned fields, but for a straightforward 'top pages' report, the current description is sufficient. The defaults and date range are handled by the schema.

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%, with all four parameters having clear descriptions and defaults. The description's phrase 'top pages by page views' adds context about the metric, but it does not meaningfully enhance the parameter semantics beyond what the schema already provides. Baseline 3 is appropriate.

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 uses a specific verb 'Get' and clearly identifies the resource: 'top pages by page views for a GA4 property.' It distinguishes itself from sibling tools like ga4_run_report by framing itself as a 'convenient shortcut for a common report.'

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 clear context: it is a shortcut for a common report, implying use when you need a quick top-pages list rather than a custom-built report. However, it does not explicitly name alternative tools like ga4_run_report or state when not to use this tool, so it misses the top tier.

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