get_group_members

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

No annotations are provided, so the description carries the burden. It discloses paging behavior and a limit, which is useful. However, it does not explicitly state that it is a read-only operation or mention permissions or error handling, though the verb 'get' largely implies safety.

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 is front-loaded with the main purpose and includes only necessary additional details about limit and paging. There is no wasted wording.

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 simple retrieval tool with an output schema, the description covers the essential functionality: what it does, the key parameter, and an important behavioral nuance (paging). It lacks explicit mention of prerequisites or edge cases, but these are not critical for this straightforward operation.

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 schema has 0% coverage from the description, but the description adds meaning by explaining that group_id is the lookup key and that limit caps results with paging. This goes beyond the bare schema definitions, though it could be more explicit about default behavior.

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 action ('Get members of a group') and identifies the key input ('by group ID'), along with an important scope constraint ('up to the specified limit, with paging'). This effectively distinguishes it from sibling tools like get_group_by_id or get_all_groups.

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 provides clear context: use this when you need members of a specific group, identified by group ID. It does not explicitly name alternatives or exclusions, but the context is specific enough for an agent to infer when to invoke it.

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