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 goes beyond them by disclosing the provenance/confidence model of the returned data — confirmed (in the regulation), derived (calculated), expected (announced, not binding) — which materially affects how an agent should present and trust each date.

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 sentences, front-loaded with the resource and its scope, followed by the status taxonomy. No filler, though the milestone enumeration is dense and slightly list-like.

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 format need not be described. The description supplies the domain scope and the status semantics an agent needs to interpret results. Minor gaps remain: nothing about language handling or date ordering/freshness.

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%, but there is only one parameter and its semantics are almost fully carried by the enum (de/en) plus default en. The description adds nothing about language behaviour, so no credit above the baseline for a single self-documenting parameter.

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 resource (key EUDI Wallet rollout dates) and enumerates the concrete milestones covered — public relying party registers, the German d-you wallet launch, mandatory acceptance for banks, energy, telecoms and very large platforms. It is clearly distinguishable from siblings like get_news, get_registers and get_standard. It stops short of explicitly naming which sibling to use instead.

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 explicit when-to-use or when-not-to-use statement, but the enumerated milestone list implies the context: an agent seeking compliance timelines or legal deadlines should call this rather than get_news or get_country. The alternative routing is left to inference.

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