get_device_parameters

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

With no annotations, the description indicates it is a read-only list operation, but lacks details on potential errors, prerequisites (e.g., valid device), or the structure of the output beyond 'indices and current values'. More context would improve transparency.

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 concise and front-loaded with the main action. The parameter list is included but does not add excessive verbosity. Could be slightly tighter, but effective.

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, the description does not need to detail return values. It sufficiently covers the tool's purpose and parameters for a list operation, though edge cases and error conditions are omitted.

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?

Despite 0% schema description coverage, the description explains both parameters: track_index as 'the track index (0-based)' and device_index as 'the device index (0-based) from get_device_list', adding useful context about origin. Constraints or valid ranges are missing.

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 'List' and clearly identifies the resource 'all parameters of a device with their indices and current values'. It distinguishes from siblings like 'set_device_parameter' by stating it is used to discover parameter indices for that tool.

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?

The description explicitly instructs to use this tool to discover parameter indices for 'set_device_parameter', providing clear context. It does not explicitly exclude other uses, but the intended use case is well-defined.

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