Get Device by UUID

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds valuable behavioral context: it explains that integer policy codes include a status_label (with specific compliance interpretation) and that uptime_minutes is sampled at last full scan and may lag. This goes beyond annotations to clarify data semantics and freshness.

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 two sentences long and front-loaded with the core purpose. Every sentence adds relevant detail (status_label, uptime behavior) without redundancy or fluff.

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?

Given no output schema, the description explains key response aspects (policy codes, uptime). However, it could provide a broader overview of the 'near-raw payload' structure or mention other important fields. Despite this, it offers sufficient context for a simple retrieval tool.

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 0%, so the description must compensate. However, the description does not explain the purpose or format of either parameter (device_uuid, output_format). It only indirectly references UUID in the tool name. No additional meaning is added for the parameters.

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 tool retrieves the 'near-raw device payload by UUID' via the canonical /servers endpoint. The verb 'get' and resource 'device payload by UUID' are specific and unambiguous, providing strong purpose clarity.

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 does not provide any guidance on when to use this tool versus alternative tools such as 'device_detail', 'get_device_full_profile', or 'list_devices'. No exclusions or context about tool selection are given.

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