Fetch all Webex users

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true. The description repeats 'Read-only' and gives the endpoint path but adds no further behavioral context such as pagination behavior, filtering semantics, or what the response contains. With annotations carrying the safety profile, this is thin added value.

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 very short and front-loaded, with no wasted prose. The endpoint path is mildly useful and the brevity suits a simple list operation, though the extreme sparseness borders on under-specification.

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 list tool with full schema coverage and rich annotations, the description is minimally adequate. However, it does not clarify whether the result is paginated, how filters combine, or what shape the output takes, and there is no output schema to cover those gaps.

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%, so all six parameters are already documented in the schema, including page, per_page, filters, and response_format. The description adds no parameter-level meaning beyond the schema, which meets the baseline of 3 when structured data does the heavy lifting.

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?

States a specific verb and resource ('Fetch all Webex users') and includes the underlying endpoint, which makes the purpose clear. It does not explicitly differentiate from close siblings like placetel_list_users or placetel_list_webex_workspaces, but the Webex-user scope is unambiguous from the name and description.

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?

There is no guidance on when to use this tool versus alternatives, nor any mention of prerequisites, filtering behavior, or pagination constraints. The agent must infer usage entirely from the name and schema.

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