tuya_send_commands

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

With no annotations, the description carries the full burden of behavioral disclosure. It states the action but omits important context such as whether the device must be online, whether the command is irreversible, what happens on failure, or whether it only affects the specified device. For a command-sending tool, this is a significant gap.

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, front-loaded sentence with zero waste. It is arguably under-specified, but the conciseness dimension rewards efficiency, and this is the most concise possible description of the core action.

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 has three required parameters, no output schema, and no annotations. The description offers only a high-level action and fails to provide essential context about command formatting, prerequisites, or integration with other Tuya tools. Given the complexity of sending commands to an IoT device, this is incomplete.

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 100%, so the schema already documents all three parameters adequately. The description adds no extra meaning beyond what the schema provides, but it does not need to repeat. The baseline of 3 applies because the schema does the heavy lifting.

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 uses a specific verb ('send control commands') and identifies the resource ('Tuya device'), making the action clear. However, it does not distinguish this tool from siblings like iot_execute_command or espconnect_send_command, which also send commands, so it is slightly generic but not vague.

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?

There is no guidance on when to use this tool versus alternatives. No when-to-use, when-not-to-use, or references to sibling tools like tuya_device_status or iot_execute_command are given. The agent must infer usage from the name alone.

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