Get group vulnerabilities

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is fully covered. The description adds real context beyond that: the Ultimate license requirement, the underlying REST path, the return wrapper shape, and the two error types raised. It omits pagination defaults/limits and how the many filter params affect behavior.

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-loads the one-line purpose and endpoint, then uses compact Args/Returns/Raises sections that each contribute. The Args section is thin rather than bloated, so the size is appropriate; only the boilerplate-style formatting costs it a point.

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 9-parameter, no-output-schema tool, the description explains fewer than half the inputs and never clarifies how the group-level result set is filtered or scoped. An agent could call it, but would be guessing about project_id/vulnerability_id/package_manager and about pagination 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 description coverage is 0% across 9 parameters, so the description must carry the burden and it largely does not. It covers only "group_id (required); optional pagination" and says nothing about project_id, vulnerability_id, package_manager, data, or api_parameters, which appear to be the actual filtering mechanism. It also calls group_id required while the schema lists no required parameters, creating ambiguity for the caller.

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 group's security vulnerability findings") plus the exact REST endpoint, which distinguishes it from gitlab_get_project_vulnerabilities and gitlab_get_vulnerability. It stops short of naming those siblings explicitly, so the differentiation is inferred from scope words rather than spelled out.

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)" tier marker is a genuinely useful precondition, and the endpoint path implies group-scoped lookup. However, it never says when to prefer this over the project-level vulnerability tool or the single-vulnerability tool, and gives no guidance on which filter params to combine.

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