  4. First observed

TDQS

D1.3/5.0
Behavior2/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description's only added behavior is usage-based billing (~$0.225 estimate, $0.075/credit), which is genuine but tangential context; it says nothing about rate limits, result caps (limit max 20, offset max 100000) or data freshness.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short, but every line is boilerplate pricing markup wrapped in HTML comments rather than front-loaded task information. The space is not earned by anything that helps invoke the tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 10-parameter, 4-required tool with 10% schema coverage, the description supplies zero functional detail. An output schema exists so return values need not be described, but the complete absence of purpose, usage and parameter context leaves the definition inadequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 10% across 10 parameters, so the description must compensate and it does not — it mentions no parameter at all. Required fields (domain, start_date, end_date, limit), enums for web_source/granularity/country, and the traffic_source semantics are left entirely undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description contains no statement of what the tool does. It is entirely a pricing/billing block, so an agent learns nothing about 'popular pages' beyond what the name and title already imply. This is a missing-purpose case rather than a clear one.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no mention of alternatives among the ~35 similarweb siblings, and no exclusions. The text addresses cost, not selection.

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