Get Release Vulnerabilities Tool

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

readOnlyHint=true already tells the agent this is a safe read, so the description only needs to add context. It confirms the payload is a CVE scan of an archived release, but says nothing about result size, default limiting behavior, or that severity filtering is available — all of which live only in the schema.

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 lean sentence with the resource and key scope front-loaded; nothing is wasted. It is arguably too terse to carry structure, but there is no filler to cut.

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?

The output schema covers return values and annotations cover safety, so the remaining burden is disambiguation among the three vulnerability tools, which this description only partially handles. Adequate but with a clear gap for a tool sitting in a dense sibling cluster.

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 100%, so all four parameters (name, digest, limit, min_severity) are already documented in structured form; the baseline of 3 applies. The description reinforces 'by digest' as the lookup key but adds no formatting, default, or usage detail beyond the 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?

States a specific verb and resource ('Get the CVE scan') plus the scope that separates it from the sibling tag/catalog vulnerability tools: a historical release identified by digest. It does not name those siblings explicitly, so an agent must infer the distinction, but the noun phrase 'historical release by digest' is a real differentiator.

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?

No when-to-use or when-not-to-use guidance is given, and no alternative is named even though get_tag_vulnerabilities_tool and get_catalog_vulnerabilities_tool are close siblings. The only routing hint ('by digest') appears in the schema's digest description, not in the tool description.

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