List GitLab project members

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds useful context about inherited members and filterable fields, but does not mention pagination behavior or permission requirements. This is adequate but not rich, consistent with the baseline for annotation-assisted tools.

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?

Single, direct sentence that is front-loaded with the main purpose and filter capability. No filler or redundancy.

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 tool has 6 parameters, an output schema, and related sibling tools. The description covers the core behavior but leaves several parameters undocumented and does not elaborate on pagination or filtering semantics beyond 'username or name'. Considering the annotations and output schema, a score of 3 reflects a minimally adequate but not thorough description.

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 only 17% (only the 'project' parameter is described). The description adds meaning to 'query' by mentioning filtering by username or name, but it does not clarify the purposes of 'user_ids' or 'skip_users', and the pagination parameters are unexplained. With low coverage, the description should compensate more fully.

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 project members, specifically direct and inherited ones, and supports optional filtering. It distinguishes itself from siblings like get_project_member (single member) and list_group_members (group members) by naming the resource and scope.

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 description conveys the appropriate context: it lists direct and inherited project members with optional name/username filtering. It does not explicitly mention alternatives or when not to use it, but the title and scope make the intended use clear relative to group/member siblings.

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