tuya_list_devices

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It states a listing action but does not explain the scope implied by device_id, authentication requirements, return format, or any side effects. This leaves significant ambiguity.

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 no wasted words. It is front-loaded and easy to parse, though it could be slightly expanded to cover critical context without becoming verbose.

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?

The tool is simple but the description is overly terse. The required device_id parameter and the claim of 'all' devices are unexplained, return values are not described, and the presence of many sibling tools suggests a need for clearer contextual differentiation, which is absent.

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 schema description covers the device_id parameter fully (100% coverage), so the baseline is met. However, the description adds no additional meaning about how device_id relates to listing 'all' devices, leaving potential confusion.

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 'List all Tuya cloud devices' uses a specific verb and resource, clearly indicating a read operation for Tuya devices. However, the presence of a required device_id parameter creates ambiguity about what 'all' means, slightly diminishing clarity.

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 about when to use this tool versus alternatives like tuya_device_status or iot_list_devices. The only differentiator is the 'Tuya' in the name, which is implicit rather than explicit.

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