sdcloud_update_device_group

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

The description only says 'Update', which implies mutation, but provides no details on what is updated, whether it's a full replace or partial update, if it's reversible, or any required permissions. With no annotations, this is insufficient.

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 a single clear sentence, which is concise. However, it could benefit from slightly more structure, such as mentioning the required parameters.

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 lack of output schema and the need for guidance on the body format, the description is incomplete. It does not explain the return value or the expected body structure beyond what the schema already states.

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 50% (body parameter has a description, uuid does not). The description adds no extra meaning beyond the schema. Baseline 3 is appropriate since coverage is not low, but no additional value is provided.

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 verb 'Update', the resource 'device group', and the identifier 'by UUID'. This distinguishes it from related tools like sdcloud_create_device_group and sdcloud_delete_device_group.

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?

No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or conditions. The description simply states the action without context.

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