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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description still adds value: it signals the corpus is 'reviewed' (curated/quality), notes the DE/EN language scope, and gives an explicit behavioral instruction to link the returned URL as the source.

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?

Front-loaded with the verb and resource, then a compact parenthetical of audience segments. The structure is efficient, though the long embedded list is dense and could be trimmed slightly.

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?

This is a low-complexity 2-parameter tool with a full output schema and safety annotations, so the description does not need to explain return shape (it does anyway) or safety. It lacks any mention of result count, pagination, or behavior when no articles match, which is a minor gap.

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?

Schema description coverage is 0%, so the description must carry the burden. It partly compensates by stating the content is German and English, which maps onto the 'lang' enum parameter, but the 'query' parameter's expected syntax/scope (free text, keyword, phrase) is never clarified.

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 names a specific verb (Search) and resource (reviewed articles) and scopes the content domains (citizens, businesses, developers) on the EUDI Wallet/d-you topic. This implicitly separates it from siblings like get_news or lookup_term, though no sibling is named explicitly.

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?

Usage is implied by the enumerated topic areas and audience segments, letting an agent infer that this is the tool for topical article lookups. However, there is no explicit when-to-use/when-not guidance or routing against alternatives such as get_news.

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