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

Annotations already declare the safe, idempotent, closed-world read profile, so the bar is lower. The description still adds real behavior: newest-first ordering, item composition (date, summary, sources flagged official vs not, Eudigo URL), and the two-overview structure — context the annotations do not carry.

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?

Two dense sentences with no filler, and the core resource/ordering statement is front-loaded before the schema notes. Slightly clause-heavy, but every clause carries information.

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?

An output schema exists, so return-value explanation is a bonus rather than a requirement, yet the description still outlines item fields. For a zero-required-parameter read tool it is essentially complete; only the interaction of `region`/`lang` defaults with the two overviews is left unstated.

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 compensate. It defines `weeks` well (latest n weekly overviews, range 1-52, which the schema lacks) and implicitly explains `region` via the Germany vs EU overviews, but `lang` is never addressed and region's null default / interaction with the two overviews is not 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?

Names a specific resource (Eudigo's weekly news on the EUDI Wallet), states ordering (newest first) and the two content scopes (Germany overview, EU overview). An agent can distinguish it from get_deadlines or get_registers, though it never explicitly contrasts with the sibling search_articles.

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?

There is no when-to-use or when-not-to-use guidance and no mention of any alternative tool. The closest thing is the content description, which only implies a digest use case; the `weeks` clause is parameter semantics, not usage routing.

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