tuya_get_device_status

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

No annotations are provided, so the description carries the full burden. It conveys that the tool returns live status data including power, brightness, color, temperature, and other properties, which is useful. However, it does not disclose error behavior (e.g., device offline, invalid name) or any consequences, though the read-only nature is self-evident.

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?

One concise sentence with the verb and resource front-loaded, followed by a parenthetical example. No redundant words, every part earns its place.

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 a simple single-parameter getter, and an output schema exists, so the description need not enumerate return fields. It covers purpose and parameter semantics adequately. The only gap is the lack of explicit usage exclusions, but overall the tool is well-defined.

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 only lists device_id as a string with zero description coverage. The description adds crucial semantics by stating the parameter accepts either a device_id or a device name (e.g., 'Living Room Light'), which is essential for correct usage and goes far 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 identifies the action ('Get the current status') and the target ('a specific Tuya device') with an example name. This distinguishes it from sibling control tools like tuya_turn_on_device or tuya_set_brightness, which perform mutations rather than reads.

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?

It implies the tool is for reading the current state of a device (as opposed to the setter/toggle siblings) and clarifies the parameter can be a device_id or a device name. However, it lacks an explicit 'use this when you need to check state rather than change it' exclusion or mention of alternatives, so it falls short of full guidance.

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