get_recent_cves

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds the data source (NVD) and the recency scope, which is useful, but says nothing about what 'recent' means (a time window? a fixed-size default result set?), whether results are paginated (the schema has no page/cursor parameter), or roughly how many items come back.

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 front-loaded sentence with zero filler, which is the right shape for a simple feed tool. It is arguably too terse rather than bloated — the brevity costs information rather than wasting space.

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-required-parameter tool there is no output schema and the description does not explain what 'recent' resolves to, how many results are returned by default, or how this relates to the other CVE tools in the catalog. An agent could call it and get results, but could not predict or control the scope of what comes back.

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?

Only one optional parameter, resultsPerPage, exists and schema description coverage is 0%, so the description is the only place semantics could be added. It says nothing about the parameter's default, maximum, or accepted range, leaving the agent to guess when setting the page size.

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 and resource ('Get recently published CVEs') plus the source ('from NVD'), which is more than a restatement of the name. It does not, however, distinguish itself from the closely related siblings circl_cve_recent, search_cve, or get_cve_detail, so an agent cannot tell from the description alone which CVE tool to pick.

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 guidance and no mention of any alternative. The 'recently published' phrase loosely implies a browsing/recent-feed use case as opposed to search_cve or get_cve_detail, but the agent must infer that, and the presence of circl_cve_recent (another recent-CVE tool from a different source) is left entirely unaddressed.

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