get_rank_and_traffic_stats

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

No annotations exist, so the description must bear the full burden of behavioral disclosure. It only states that it retrieves time series data but omits details on authentication, rate limits, error handling, or data boundaries.

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 a single 12-word sentence, which is efficient but lacks necessary detail. It is not verbose, but the minimalism comes at the cost of completeness.

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 one parameter, zero schema descriptions, no output schema, and no annotations, the description is extremely sparse. It fails to explain the output format, time range, or how to interpret the data, leaving 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 schema has 0% description coverage for its single parameter site_url. The tool description adds no additional meaning beyond the parameter name; it does not explain format, expected values, or behavior if omitted.

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 verb 'Get' and the resource 'daily impressions/clicks rank & traffic time series' and specifies scope 'for a site'. It is distinguishable from sibling tools like get_crawl_stats or get_keyword_stats, though it may overlap slightly with get_url_traffic_info.

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?

No guidance is provided on when to use this tool vs. alternatives, nor are there any prerequisites or exclusions mentioned. The agent receives no context for tool selection.

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