exchange_get_distribution_group_member

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

No annotations are provided, so the description carries the full behavioral burden. 'Get' implies a read operation, but the description does not disclose return shape, pagination, permission requirements, or what happens if the identity does not resolve to a distribution group.

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 extremely concise, with no wasted words, but it is underspecified rather than efficiently informative. Front-loading is good, yet the single fragment fails to provide enough supporting context.

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 one-parameter tool with no annotations and no output schema, the description should at least clarify the meaning of 'identity' and what the caller can expect from the result. It does neither, leaving the agent to make assumptions about how to invoke the tool correctly.

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 0%, so the description must compensate, but it does not. The single required parameter 'identity' remains undocumented; the tool name and description strongly imply it is the distribution group identity, but this is never stated explicitly, and the description does not clarify whether it expects a group ID, alias, or display name.

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 'Get distribution group members' names a specific verb ('get') and resource ('distribution group members'), making the core purpose identifiable. It does not explicitly differentiate from sibling tools like exchange_list_distribution_groups, which are about listing groups rather than members, but the intent is largely 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 usage: an agent should call this tool when it needs members of a distribution group. However, it offers no explicit guidance on when to prefer this over related tools such as exchange_list_distribution_groups or exchange_list_dynamic_distribution_groups, and it names no alternatives or exclusions.

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