B3/5.0
Behavior2/5

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

Annotations already declare readOnly, idempotent, non-destructive, and open-world behavior. The description adds only the API endpoint and does not disclose response data, authentication needs, rate limits, or other behavioral context beyond what annotations provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short lines, front-loaded with the purpose and no filler. The endpoint reference adds compact context without bloat.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read tool the annotations cover safety, but with no output schema the description does not explain what 'data' is returned. It also omits guidance on the optional profile parameter, leaving meaningful context gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema documents the required path.id as 'Device ID' and profile as a defaulted string, while the description only echoes {id} in the URL and never explains the profile parameter or the nested path object. With 50% schema description coverage, the description does not compensate for the undocumented parts.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

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 the data of a device,' reinforced by the endpoint /api/devices/{id}. It is clearly distinct from update/list siblings, but it does not explicitly differentiate itself from the many other device-scoped read tools such as trmnl_get_device_logs or trmnl_get_device_timeline.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use, prerequisites, or alternatives are stated. Usage is only implied by the verb and the /api/devices/{id} path, so an agent must infer that this is for retrieving core device data when a device ID is known.

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