get_media_grabbers_devices_by_device_id

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

Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds no additional behavioral context such as return format, error cases, authentication needs, or relationship to device discovery/listing. It contributes nothing beyond the 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 very short and front-loaded with the core statement 'Get device details.' The endpoint and Args sections are clearly structured. Minor redundancy exists between the prose and the HTTP GET line, but overall it is efficient.

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 simple one-parameter getter with an output schema and safety annotations, the description is nearly sufficient. However, it lacks any guidance on how the device_id relates to list_media_grabbers_devices or what kind of device is being queried, leaving minor gaps for an agent.

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. It only restates 'device_id: The ID of the device,' which adds little beyond the schema's title 'Device Id'. It does not explain where to obtain the ID, its format beyond integer, or any constraints.

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 'Get device details' with a specific verb and resource, and the endpoint path identifies the exact resource. It doesn't explicitly differentiate from sibling tools like get_media_grabbers_devices_by_device_id_channels, but 'details' conveys the base-level scope.

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 endpoint and argument imply usage when a device_id is known and device details are needed. However, there is no explicit guidance on when to use this versus related list or sub-resource endpoints, nor any exclusions or alternatives mentioned.

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