get_group_members

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

No annotations are provided, so the description must convey behavioral traits. It states 'retrieves' indicating a read-only operation, but does not disclose error behavior for invalid group_id, permission requirements, or any side effects. This is minimally adequate for a simple query.

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 with no wasted words. It front-loads the verb and clearly communicates the tool's purpose and scope in an efficient manner.

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 low complexity (1 required param, no output schema), the description covers the basic functionality but omits what the return value looks like (e.g., an array of user objects or IDs). This could be improved for completeness.

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 100% for the single parameter 'group_id', which is described as 'Group ID'. The description adds no additional meaning or context beyond the schema, so it meets the baseline for high coverage without extra value.

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 uses the specific verb 'Retrieves' and noun 'complete member list of an existing group chat', clearly stating the tool's function. It distinguishes from sibling tools like create_group, dismiss_group, and others that perform different actions on 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 implies usage context (retrieving members of an existing group) but provides no explicit when-to-use or when-not-to-use guidance relative to alternatives like get_user_info or get_private_messages. Usage is inferred from the tool's name and function.

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