list_devices

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

The description discloses that the tool returns specific fields, which is good. However, it does not mention that results are paginated (despite the 'page_size' and 'after' parameters) or describe the default behavior. No annotations are provided, so the description carries the full burden, leaving some gaps.

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 short (one sentence plus a list of returned fields) and focused. It could be improved by front-loading the purpose and explaining pagination, but it is not 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?

With 3 parameters and no output schema, the description covers the returned fields but lacks details on response structure, error handling, and ordering. Given the number of sibling tools, the description is adequate but not fully self-sufficient.

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 input schema has 100% description coverage, so the baseline is 3. The description does not add extra meaning beyond the schema descriptions for the parameters (e.g., explaining that 'after' is a cursor for pagination). It merely states the overall purpose.

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 verb 'List' and the resource 'all devices managed by NinjaOne'. It also lists the returned fields: device name, OS, etc. However, it does not explicitly differentiate from sibling tools like 'list_organization_devices' or 'get_device', which could cause confusion.

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 provides no guidance on when to use this tool versus alternatives such as 'get_device' for a single device or 'list_organization_devices' for filtered lists. There is no mention of prerequisites or typical scenarios.

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