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

With no annotations, the description carries the full behavioral burden and it is thin: it does not state that this is a read-only aggregation of external feeds, mention API/auth requirements, rate limits, caching or data freshness for the KEV/EPSS/CVSS sources, or describe how the correlation is ranked. Naming the three upstream data sources gives some behavioral context, but key operational traits are absent.

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 no filler or repetition. It is efficient, though it could have traded a few of the source acronyms for one clause on behavior or scope.

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 four-parameter scanner with no output schema and no annotations, the description covers the 'what' but not the 'how' — return shape, ranking method, source freshness, and the unexplained 'specific_cves' mode all remain unaddressed. Adequate as a minimum-viable definition, but an agent cannot fully predict the result or the mode-specific behavior.

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 all four parameters already carry their own descriptions, which sets the baseline at 3. The tool description adds no meaning about how mode, minEpssScore, vendorFilter, or maxResults interact — notably it never explains that 'specific_cves' mode would need a CVE identifier, for which no parameter exists.

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 (correlate) and three concrete resources (CISA KEV, FIRST.org 30-day EPSS, NVD CVSS v3) with the stated goal of DevSecOps prioritization. No sibling tool in the list covers vulnerability data, so differentiation is implicit rather than needing to be spelled out. It stops short of saying what the tool actually returns (a ranked CVE list, a scan report, etc.).

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 through the phrase 'for DevSecOps prioritization'; there is no explicit when-to-use, when-not-to-use, or prerequisite guidance. No alternative tool is named, though no sibling overlaps functionally. The agent must infer that this is for vulnerability triage based on the intent phrase alone.

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