Get Device by UUID

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

Annotations already provide readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds value by specifying the API version ('Server Groups API v2') and the lookup method ('UUID-based'), which are not covered by annotations. There is no contradiction with annotations.

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 brief with two sentences. The first sentence is front-loaded and effective. The second sentence is somewhat redundant ('Provides device information via UUID-based lookup') and could be merged. Overall efficient but not maximally concise.

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 the tool's simplicity (2 parameters, output schema exists), the description is mostly adequate. It specifies the API version and lookup method. However, it lacks mention of authentication requirements or any limitations. The presence of an output schema reduces the need to explain return values.

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%, meaning parameters have no descriptions. The tool description only mentions 'device details by UUID', which implies the 'device_uuid' parameter but does not explain 'output_format'. With low coverage, the description fails to compensate for missing parameter documentation.

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'), the resource ('device details'), and the method ('by UUID'). It references the specific API version ('Server Groups API v2'), which distinguishes it from other device retrieval tools like 'device_detail' or 'list_devices' that may use different identifiers or endpoints.

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 implies usage for UUID-based lookup but does not provide explicit guidance on when to choose this tool over alternatives (e.g., 'device_detail', 'get_device_full_profile'). No when-not-to-use or context for exclusion is given.

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