euvd_licence_info

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

No annotations exist, so the description carries the full burden, and it does establish that the tool returns static policy/attribution metadata rather than live vulnerability data. However, it does not state that the operation is read-only and side-effect free, nor whether the policy is stable or could change, leaving minor behavioral questions open.

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?

A single sentence with no filler, front-loading the action and the exact resource. Every word earns its place, and the acronym expansion adds real disambiguation value.

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?

For a no-parameter metadata fetch with no output schema, the description identifies the content adequately enough to call it confidently. A brief note on what the metadata contains (e.g., licence terms vs. citation format) would close the remaining 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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. No parameter detail is missing because the schema is an empty object.

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?

States a specific verb ('Return') and a precisely named resource ('ENISA European Vulnerability Database (EUVD) reuse policy and attribution metadata'), expanding the acronym so the agent knows the data source. It is clearly distinct from the sibling data tools like euvd_search_vulnerabilities and euvd_lookup_by_id, though it never explicitly names those alternatives.

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?

The usage is implied rather than stated: an agent can infer this is the call to make when it needs licence terms or attribution text before reusing EUVD data. There is no explicit 'call this when...' or note about whether it must be called before the other euvd_* tools.

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