List Group Members

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false. The description adds the important detail that it returns effective members including inherited ones. However, it does not disclose pagination, sorting, error behavior, or whether the response includes all fields, which would be helpful.

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 very concise at one sentence. While the main action is stated, the brevity leaves out essential usage context. It is front-loaded with the key action, but the single sentence fails to earn its place by omitting parameter and output details that an agent would need.

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?

Given the tool has 4 parameters with no schema descriptions, no output schema, and no usage notes, the description is severely incomplete. It does not explain pagination, query filtering, or the structure of returned data. An agent would struggle to use this tool effectively without external documentation.

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%, meaning none of the four parameters have descriptions in the input schema. The description does not mention any parameter meanings, usage, or constraints (e.g., page, per_page, query). This forces the AI to infer semantics from parameter names alone, which is insufficient.

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 clearly states the tool lists group members and specifies it includes inherited members. This verb+resource with a key detail distinguishes it from project member tools among siblings. However, it could be more explicit about the scope (e.g., 'all members with access to the group').

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 explicit guidance on when to use this tool versus alternatives. Among siblings, gitlab_get_project_members serves a different resource, but no direct comparator for group members exists. The description implies its use for group member listing but lacks when-not-to-use or alternative suggestions.

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