get_url_traffic_info

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

No annotations are provided, so the description must convey behavioral traits. It implies a read operation but does not explicitly state safety, idempotency, or permission requirements. The description offers minimal transparency beyond the fact that it returns traffic data.

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 brief with two sentences, front-loading the main purpose. It is efficient, but the second sentence could be integrated or expanded slightly. Still, it earns its place with minimal 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?

For a tool with two required parameters, no output schema, and no annotations, the description is sparse. It covers the basic purpose and a parameter feature but omits details like return structure, date range, or any side effects. This leaves the agent underinformed.

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 has 0% description coverage, so the description must compensate. It only explains that the 'url' parameter can include a 'domain:' prefix for domain-level info, but the 'site_url' parameter is left entirely unexplained. This partial explanation is insufficient.

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 that the tool retrieves index traffic details (clicks, impressions) for a single page, using the verb 'get' and specifying the resource. It also mentions a special case with 'domain:' prefix. However, it does not explicitly differentiate it from sibling tools like get_page_stats or get_query_stats that might also return traffic data.

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 no guidance on when to use this tool versus alternatives such as get_page_stats or get_url_info. It only gives a technical detail about the 'domain:' prefix but lacks context on typical use cases or prerequisites.

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