list_mobility_workspace_admins

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

With no annotations, the description carries the full behavioral burden, yet it only states that admins are listed. It does not confirm the operation is read-only, mention any permission or scope requirements, or describe pagination/result size limits.

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?

A single short sentence with no filler, which is structurally clean. However, its brevity reflects under-specification rather than disciplined concision, since essential context is simply absent.

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?

An output schema exists, so return values need not be enumerated, but for a list tool with zero annotations and an undocumented required parameter the definition is too thin. It omits how workspace_id is obtained and what the call requires.

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 coverage is only 50% and the required workspace_id has no schema description; the tool description adds nothing about it either, so an agent gets no help on where a workspace_id comes from (presumably list_mobility_workspaces). The optional controller parameter is documented in the schema, not the description.

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 gives a specific verb (list) plus a precise resource (admins of a UniFi Mobility workspace), so an agent immediately knows what it returns. It does not, however, distinguish itself from nearby siblings such as list_mobility_workspaces or list_mobility_devices, so it lands just short of a 5.

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 call this versus list_mobility_workspaces, get_mobility_device, or any other sibling, and no prerequisites or exclusions are stated. The agent must infer usage entirely from the name.

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