get_latest_critical_cves

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

No annotations are provided, so the description carries the full behavioral burden, yet it only offers the vague phrase 'synchronized database.' It does not state auth requirements, rate limits, sort order, or whether this is read-only (implied by 'Fetch' but unconfirmed). Return format is covered by the output schema, so that omission is acceptable.

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?

One front-loaded purpose sentence followed by a compact, conventional Args block; nothing is redundant. Slightly more value could be added within the same footprint, but there is no wasted text.

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?

With an output schema present, return values need not be described, and all three parameters are fully documented with ranges and defaults. The main gap is the absence of behavioral context (source freshness, ordering, permissions) for an unannotated tool, but the core calling contract is complete.

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, and it does: it documents all three parameters with meaning, valid ranges (days 1-90, min_cvss 7.0-10.0, limit 1-50) and defaults beyond what the bare schema shows. Only minor interpretive detail (e.g., what 'critical' implies relative to min_cvss) is missing.

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 with scope: 'Fetch newly published critical vulnerabilities from the synchronized database.' Combined with the name, an agent understands this returns recent high-severity CVEs, distinct in spirit from get_cve_details (single CVE) and get_top_kevs (KEV catalog), though it never explicitly names or contrasts those siblings.

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?

Usage is only implied: the 'newly published' framing plus the days parameter signals a recency-scan use case, but there is no explicit when-to-use, when-not-to-use, or routing guidance versus search_vulnerabilities or get_top_kevs. An agent must infer when this beats a general search.

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