TDQS

A4.5/5.0
Behavior5/5

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

Annotations already declare readOnlyHint and openWorldHint, but the description adds substantial context: it identifies the public Ads Transparency Center as the source, states no private account access is needed, specifies up to 40 ads returned, mentions the optional region filter, and discloses pricing details including that no ads found is free.

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

Conciseness5/5

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

The description is front-loaded with the core purpose and returned data, then adds usage context and pricing in concise, non-repetitive sentences. Every sentence contributes useful information without bloat.

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

Completeness5/5

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

Given that an output schema exists and annotations cover safety semantics, the description is complete enough for an agent to call the tool correctly. It explains the data source, what is returned, optional filtering, privacy scope, and cost model.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all three parameters well, including the domain format and region enum. The description reinforces the domain lookup and optional region filter but does not add meaningful semantics beyond that, and it does not mention the context parameter. Baseline 3 is appropriate when the schema does the heavy lifting.

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

Purpose5/5

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

The description uses a specific verb and resource: a Google Ads lookup for a company domain via the public Ads Transparency Center. It names the exact returned data (advertiser status, estimated ad count, up to 40 ads with format, dates, links) and an optional region filter, making the tool's purpose distinct and concrete.

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

Usage Guidelines4/5

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

It clearly says to use the tool when researching a company's or competitor's advertising. It also clarifies that the source is public and requires no private account access, which helps an agent decide applicability. It does not name a direct sibling alternative or explicit exclusion case, so it falls short of a 5.

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