list_users

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

No annotations are provided, so the description carries the full burden. The verb 'List' suggests a read-only, non-destructive operation, and the lack of parameters implies no side effects beyond fetching data. However, it does not explicitly confirm read-only status or mention potential pagination or rate limits, leaving minor ambiguity.

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, concise sentence that conveys all necessary information without extraneous detail. It is front-loaded with the action and resource, making it easy to parse quickly.

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 list operation with no parameters, the description is sufficient for an agent to invoke it correctly. However, it does not specify the structure or content of the returned user list (e.g., fields, ordering), which could be relevant for downstream processing. Given the simplicity, this is a minor gap.

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 tool has zero parameters, and the description correctly indicates no inputs are required. There is no schema to document, and the description adequately conveys that no additional arguments are needed to invoke the listing.

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 ('List') and the target resource ('all users') from the Clockodo API. It is specific and distinguishable from sibling tools like 'get_my_clock' or 'list_customers', making its purpose unambiguous.

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 does not explicitly state when to use this tool over alternatives, but its name and phrase 'all users' imply it is for broad user enumeration, contrasting with the 'my' prefixed tools that focus on the authenticated user. The context from sibling tools provides implicit guidance, though explicit usage conditions would be clearer.

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