gam_admin_print_group_members

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

No annotations are provided, so the description carries the full burden. It discloses the pagination behavior ('paginating until exhaustion'), which is a key behavioral trait. However, it does not mention permissions, rate limits, or whether the tool only lists active members (vs. all members). For a read operation, this is adequate but could be more thorough.

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 a single sentence that conveys the core purpose and a key behavior (pagination). It is concise without being under-specified. It earns a high score for efficiency, though it could be slightly more informative without sacrificing conciseness.

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 no output schema, the description should explain the return format or content structure. It does not. While it mentions pagination, it omits what the output contains (e.g., list of emails, metadata). For a listing tool with a sibling like gam_admin_print_groups (which likely outputs structured data), this is insufficiently complete.

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 input schema covers 67% of parameters with descriptions (adminUserEmail and groupEmail). The description adds no additional meaning for any parameter; it does not explain the format parameter or any format-related behavior. With moderate schema coverage, the description fails to compensate for the undocumented parameter or add value beyond the schema.

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 'Lists active members of a group', which specifies the verb and resource. It also mentions pagination behavior ('paginating until exhaustion'), distinguishing it from sibling tools like gam_admin_print_groups (list groups) and gam_admin_sync_group_members (sync members). It could be more explicit about the distinction but is sufficiently clear.

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 implies it is used for listing active group members, providing context for when to use it. However, it does not explicitly state when not to use it or mention alternatives. No prerequisites or exclusions are given, so guidance is implicit rather than explicit.

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