putdevicegroup

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'Updates' but does not clarify whether this is a partial or full update, what fields can be changed (only 'name' as per schema), what happens on failure, or any authorization or idempotency details.

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 sentence, which is concise but overly minimal. It front-loads the verb and resource but omits important details that could be included without becoming verbose. The brevity comes at the cost of informativeness.

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, no output schema, no annotations), the description is incomplete. It does not explain success/error responses, permissible values beyond the schema, or any interactions with other entities. It meets only the bare minimum for identifying the tool's core action.

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?

The input schema already provides descriptions for both parameters (id: 'Group id', requestBody: 'Device group' with name description), resulting in 100% schema coverage. The description adds no additional meaning beyond what the schema offers, earning the baseline score.

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 'Updates a device group', which specifies the verb and resource. However, it does not differentiate this PUT operation from any other potential update tool like PATCH, but since no sibling patch for device groups exists, it is adequately clear.

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 provides no guidance on when to use this tool versus alternatives such as 'postdevicegroup' or 'deletedevicegroup'. There is no mention of prerequisites, context, or circumstances that would make this tool inappropriate.

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