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

With no annotations provided, the description must convey behavioral traits such as read-only operation, output format, or data source. It only mentions 'latest critical CVEs' and filtering, leaving the agent to infer that this is a safe query tool. The absence of any disclosure about response structure or limitations is a gap.

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?

The description is a single, tightly packed sentence that front-loads the core purpose and immediately mentions filtering. There is no fluff or repetition; every word earns its place.

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?

Given the lack of an output schema and annotations, the description is too sparse. It does not explain what the 'briefing' includes, how results are returned, or any edge cases. With four optional parameters, more context about the intended response would make the tool easier to invoke correctly.

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 coverage is 100%, so the baseline is 3. The description's reference to 'severity and banking relevance' merely echoes the existing schema descriptions for severity and banking_only, adding no new semantic detail beyond what structured data already provides.

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 clearly states the tool provides the latest critical CVEs, with a focus on daily DORA ICT risk briefings. It distinguishes itself from sibling tools like cve_search by emphasizing recency and criticality, though it lacks an explicit verb like 'retrieve' or 'list'.

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 phrase 'daily DORA ICT risk briefing' implies a recurring use case, and the mention of filters suggests how to narrow results. However, it does not explicitly state when to use this tool versus alternatives like cve_search or kev_list, nor does it provide exclusions.

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