Get project vulnerabilities

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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds real value beyond them: the underlying REST path, the fact that the return value is a wrapper holding both the raw response and a parsed list of vulnerability dicts, and two named failure modes (MissingParameterError, ParameterError). It stops short of covering pagination limits or auth scope.

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 the purpose in the first sentence, then cleanly separated into endpoint, Args, Returns, and Raises blocks. The structure is efficient, with only minor boilerplate in the kwargs/Returns phrasing.

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?

Covers the return shape and error conditions adequately for a tool with no output schema, but for a 9-parameter read tool with zero schema documentation it leaves too many filtering and pagination parameters (vulnerability_id, package_manager, max_pages, group_id) unexplained for an agent to invoke it confidently.

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 0% across 9 parameters, so the description carries the full burden and largely fails: it only mentions project_id and unspecified "optional pagination." Filters present in the schema such as vulnerability_id, package_manager, and group_id are never explained, so an agent cannot tell whether they narrow results or alter behavior. It does correctly disclose that project_id is required at runtime despite the schema marking it nullable.

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 a project's security vulnerabilities") and scopes it to the project level, which distinguishes it from the sibling gitlab_get_group_vulnerabilities. It also flags the Ultimate-tier licensing requirement, though it never explicitly names the group-level or single-vulnerability alternatives.

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?

The "(Ultimate)" marker is a genuine prerequisite that tells an agent the call will fail on lower tiers, and the endpoint path implies it is a read-only listing. However, there is no guidance on when to prefer this over gitlab_get_group_vulnerabilities or gitlab_get_vulnerability, and no exclusion criteria.

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