device_devices__get_device

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds only the HTTP route, and says nothing about what happens when the UUID is unknown, what the payload contains, or any permissions needed.

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?

One short sentence, front-loaded with the verb and resource, with no filler. The parenthetical endpoint and the bracketed "[device]" are mild redundancy, but nothing bloats the definition.

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?

For a by-ID read with no output schema, the description never indicates what a device detail record includes or how it differs from the richer profile tool. An agent knows how to call it but not what it will receive or why it should prefer it over a sibling.

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 100%, with deviceUuid documented as a required UUID reference and fields documented in detail, so the schema carries the semantic load. The description contributes nothing about deviceUuid or about the server-side projection behavior of fields, which keeps this at the baseline.

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 states a specific verb and resource ("Get device details") plus the backing endpoint path, so the basic purpose is unambiguous. However, it is close to a restatement of the tool name and does nothing to separate it from close siblings such as device_devices__batch_get_devices or device_full_profile.

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 at all: nothing says to call this for a single device by UUID rather than batch_get_devices, list_devices, or device_full_profile. The agent must infer the selection rule entirely from sibling names.

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