list_mobility_devices

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

No annotations are provided, so the description carries the full burden, yet it says nothing about pagination behavior despite limit/offset parameters, nor about result ordering, scoping, or read-only semantics. Only the presence of an output schema mitigates the gap.

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 clean sentence with no waste and the resource front-loaded. It is efficient, though brevity here stems partly from under-specification rather than tight editing.

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 means return values need not be explained, but for a paginated list tool with four parameters, undocumented limit/offset semantics and no annotation coverage leave the definition incomplete for correct invocation.

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 25% – only 'controller' has a schema description, while limit, offset, and workspace_id are undocumented. The description adds no parameter meaning at all, so it fails to compensate for the low coverage.

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 ('List') and resource ('devices') scoped to a 'UniFi Mobility workspace', which separates it from siblings like list_mobility_workspaces and list_mobility_device_clients. It does not explicitly name those siblings, so it stops 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 when-to-use guidance, no mention of alternatives, and no statement of prerequisites beyond the implied required workspace_id. The agent must infer that this is the bulk-list counterpart to get_mobility_device.

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