get_cve_details

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

With no annotations, the description carries the full burden; it does disclose the data sources and enrichment layers returned, which is the key behavioral trait. However, it says nothing about read-only/non-mutating behavior, external API dependencies, rate limits, latency, caching, or failure modes (e.g., unknown CVE IDs), which are relevant for a tool aggregating multiple upstream feeds.

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 front-loaded with the purpose and return contents, followed by a compact Args block. Phrasing like 'comprehensive, deeply enriched 360-degree security profile' is slightly marketing-flavored, but the enumerated data sources keep it informative rather than bloated.

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?

An output schema exists, so return values need not be fully specified, and the description still summarizes them well. Given a one-parameter, read-style lookup with a defined output schema, the description is sufficient, though it could add a note on identifier format tolerance or failure behavior for unknown CVEs.

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 reasonably: it names the parameter and defines it as a 'Standardized CVE identifier' with concrete format examples ('CVE-2021-44228', 'CVE-2024-3094'). It stops short of noting validation behavior or case sensitivity, but the format guidance materially exceeds the bare schema.

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 uses a specific verb ('Retrieve') with a clearly defined resource (a CVE security profile) and enumerates the exact data returned: NVD CVSS, CISA KEV, FIRST.org EPSS, MITRE ATT&CK, and risk assessment. This differentiates it from siblings like get_epss_score (single-signal) and search_vulnerabilities (discovery-oriented), making the distinct role of this lookup tool obvious.

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 tool takes a single cve_id and returns a comprehensive profile, suggesting it is for deep-dive lookup once an identifier is known, versus the sibling search/browse tools. There is no explicit 'use this when...' statement, no exclusions, and no mention of when a lighter sibling (e.g., get_epss_score) would suffice.

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