TDQS

A3.9/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive. The description adds behavioral context beyond that: supports Solr filter expressions (with example), pagination via rows/start, sorting, and returns specific fields (titles, descriptions, publisher info). This enriches the agent's understanding of what the tool does operationally.

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?

Two sentences with no fluff: the first states the core purpose and resource, the second lists supported features and return fields. Every phrase contributes useful information, and the most important detail (what it searches) is front-loaded.

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

Completeness4/5

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

For a read-only search tool with an output schema, the description covers the essential behaviors: query, filtering, pagination, sorting, and return content. Minor gaps like sort syntax and start semantics are not detailed, but annotations and the output schema fill most of the remaining context. Overall, a well-rounded definition.

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

Parameters4/5

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

Schema description coverage is only 40%, but the description compensates well: it explains 'query' as free-text, 'fq' as Solr filter (with example), 'rows/start' as pagination, and 'sort' as sorting. It doesn't give exact syntax for sort or start defaults, but it adds meaning to all parameters beyond the sparse schema.

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

Purpose4/5

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

The description clearly identifies the resource ('EU open-data portal (data.europa.eu)') and the action ('Search ... for datasets by free-text query'), which makes the tool's purpose obvious. It doesn't explicitly name or differentiate sibling tools like search_within, but the specific portal reference largely avoids ambiguity.

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

Usage Guidelines3/5

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

The intended context is implied through the named portal and dataset focus, but the description gives no explicit when-to-use guidance, exclusions, or alternatives. An agent can infer it's for EU open-data dataset lookups, but there's no clear statement about when to choose this over similar search tools.

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