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

No annotations are provided, so the description carries the full burden. It discloses the return shape ('list of affected products with organization information and version details') and the ID-resolution prerequisite, which is useful. However, it does not confirm this is a read-only operation, nor mention pagination, result caps, or behavior when the CVE has no known affected products.

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?

Front-loaded with purpose, followed by input, fallback, and return value in a compact order. The final sentence ('Use this to understand the scope and impact') is somewhat redundant with the opening, keeping it short of ideal economy.

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 single-parameter read lookup with no output schema, the description covers purpose, input forms, the fallback path, and what is returned. Missing only operational details like pagination or empty-result handling, which are minor for this tool's complexity.

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 parameter is already documented, and the description adds workflow semantics beyond the schema: how to obtain the identifier when missing. It doesn't clarify format distinctions (e.g., UUID source or case sensitivity), but the addition over the schema is real.

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?

Names a specific verb ('Find') and resource ('technology products and software affected by a specific vulnerability'), so an agent can tell this apart from getProduct/listProducts/getVulnerability. It doesn't explicitly contrast with getVulnerability, which likely also surfaces affected products, so the sibling differentiation is implicit rather than stated.

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?

Gives a clear entry condition ('Provide either a CVE ID or a vulnerability UUID') and an explicit prerequisite workflow ('If you do not have a CVE ID, first use the vulnerability search tool'). It never states when NOT to use it or what to do if the ID is unknown, but the positive guidance is concrete.

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