get_device_parameters

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

No annotations are provided, so the description bears full responsibility. It correctly implies a read-only operation by describing what is listed, but it does not disclose potential behaviors like pagination, sorting, or error conditions. This is adequate for a simple read tool.

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?

Two concise sentences convey the purpose, usage context, and parameter descriptions with no wasted words. Front-loads the primary action and return structure.

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?

Given the existence of an output schema (which covers return values), the description fully covers the tool's function, parameters, and usage context. No significant gaps remain for this simple parameter listing tool.

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 input schema has 0% description coverage per context, but the tool description explicitly explains both parameters: track_index as 'The track holding the device' and device_index as 'The device's index in that track's chain (0 = first)'. This adds meaning beyond the raw 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 lists every parameter of a device with specific fields (index, name, current value, min, max). It distinguishes itself from siblings by explicitly positioning it as a prerequisite for set_device_parameter.

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?

Explicitly says 'Use this before set_device_parameter to find the right parameter and its range.' This provides clear when-to-use guidance, though it could elaborate on when not to use it (e.g., if parameters are already known).

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