Batch Update Devices

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

Annotations indicate destructiveHint=true and readOnlyHint=false. The description adds the 500 device limit and example action format, which are behavioral traits not captured in annotations. However, it does not discuss partial failure handling or rollback behavior.

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 concise sentence with an example, front-loading the key information. Every part is necessary; no wasted words.

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 bulk update tool with 3 parameters, destructive annotation, and an output schema (reducing need to describe return values), the description is fairly complete. It explains the purpose, limit, and action format. Minor gaps: no mention of prerequisites or error scenarios.

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 provides an example of the actions parameter (tag apply/remove), adding meaning beyond the raw schema. However, it does not explain the devices parameter (list of IDs) or request_id. The compensation is partial.

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 applies bulk attribute actions to many devices at once, with a limit of 500 devices. It gives an example action format, distinguishing it from single-device updates like update_device. The verb 'apply' and resource 'devices' are specific and unambiguous.

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 explicit guidance on when to use this tool versus alternatives such as update_device or advanced_device_search. The limit of 500 and action format provide implicit context, but the description does not mention exclusions or prerequisites.

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