list_users

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

Annotations already declare readOnlyHint=true, which the description aligns with by saying 'list'. However, the description adds no extra behavioral info such as pagination behavior, response format, or rate limits. With annotations covering safety, a score of 3 is appropriate for not adding value beyond the structured field.

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 short sentence with no wasted words. It is appropriately concise for a simple listing tool, though it could include brief notes on pagination or filtering without becoming verbose.

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?

Description lacks information about the return value (no output schema). For a listing tool, agent needs to know if response is paginated, what the fields are, etc. This gap makes it incomplete for effective use.

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?

Input schema has 100% coverage with clear descriptions for both 'offset' and 'username'. The description does not add any extra meaning beyond what the schema provides, so baseline 3 is correct.

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?

Description explicitly states verb 'List', resource 'users', and scope 'in your Qualtrics organization'. It clearly distinguishes from sibling 'get_user' which targets a single user, and it's not ambiguous with other list tools like 'list_contacts' which reference different resources.

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?

No guidance on when to use this tool versus alternatives like 'get_user' for a single user. Does not mention pagination behavior or that it returns a list of users. The presence of an 'offset' parameter implies pagination but description doesn't clarify usage context.

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