get_private_devices

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

No annotations are provided, so the description must fully disclose behavioral traits. It only states the tool returns 'device information and settings', but does not mention whether results are paginated, require authentication, or if it returns all devices at once. The description is insufficient for safe invocation.

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 concise—one sentence front-loading the key information. Every word is necessary, though more detail could be added without losing conciseness.

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 no parameters and an output schema present, the description is adequate but not complete. It fails to mention common list-tool behaviors like ordering, filtering capabilities, or whether results are cached. For a tool with no inputs, the description should provide more context about what 'private devices' means.

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?

There are no parameters (0 params, 100% schema coverage), so baseline is 4. The description adds minimal meaning beyond the schema by specifying the output content ('device information and settings'), but it is vague and does not elaborate on what fields are included.

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 ('get a list') and the resource ('private devices') and mentions the content ('device information and settings'). It distinguishes from siblings like get_specific_device (which returns a single device) but does not explicitly differentiate from other list tools like get_devices_status or get_real_device_jobs.

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?

No guidance on when to use this tool versus alternatives like get_devices_status (which may return different subsets) or get_specific_device. The description implies using it to list private devices, but provides no context on filtering, prerequisites, or exclusions.

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