Remove Devices from Group

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

Annotations already declare destructiveHint=true and readOnlyHint=false. The description adds that the name must be a valid device group and references get_device_groups, but does not disclose additional behavioral traits like whether the devices themselves are deleted or if the operation is reversible. It provides some context beyond annotations but not extensive.

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 structured logically in three short paragraphs, but there is redundancy: the first sentence ('Remove one or more devices from a device group') essentially repeats the second sentence ('This tool will remove one or more devices from a named device group'). Still, it is concise and readable.

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 removal tool with an output schema, the description covers the key points: parameters, prerequisite of a valid group name, and how to find groups. It does not address edge cases like an empty devices list or error handling, but those may be covered by the output schema or are not critical for a well-scoped operation.

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 coverage is 100% and both parameters have descriptions. The description goes further by explaining that 'name' must be a valid group and that 'devices' is a list, plus it directs users to get_device_groups for valid names, adding value beyond the schema.

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 tool's purpose with a specific verb ('remove') and resource ('devices from a device group'). It is unambiguous and distinguishes itself from the sibling 'add_devices_to_group' by direction of the operation.

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 useful context: the name must be a valid device group and points to the get_device_groups tool for finding valid groups. However, it does not explicitly mention when to use this tool over alternatives, such as add_devices_to_group, or when not to use it.

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