Api vulnerabilities severity retrieve

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

Annotations declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, but the description says the endpoint allows vulnerabilities to be 'viewed or edited'. The editing claim conflicts with the read-only annotation and misleads the agent about a mutation capability. No additional behavioral context (what is returned, that this is a choice/enum lookup) is provided.

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?

It is a single short sentence with no wasted words and nothing to trim, but the brevity comes from under-specification rather than efficiency – it conveys almost no usable information.

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 no parameters and no output schema, the description is the only place to explain that this endpoint enumerates available vulnerability severity values. Instead it gives a generic CRUD sentence, leaving the agent unable to decide between this and the many other vulnerabilities_* retrieve endpoints.

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?

The tool takes zero parameters and the schema is empty, so there is nothing for the description to disambiguate. Baseline 4 applies for a no-parameter tool.

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 sentence is generic DRF boilerplate that restates the resource name without saying anything about 'severity' – the actual subject of the endpoint. It does not distinguish this from siblings such as vulnerabilities_status_retrieve, findings_severity_retrieve, or security_exceptions_severity_retrieve, so an agent cannot tell what this call actually returns.

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?

There is no guidance on when to call this versus vulnerabilities_list, vulnerabilities_retrieve, or the other severity endpoints. Combined with the 'viewed or edited' phrasing, an agent gets no signal about whether this is the right tool for enumerating severity choices.

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