set_master_device_parameter

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

No annotations are provided, so the description carries the burden for behavioral disclosure. It explains the zero-based indexing and the range requirement for value, which are useful, but it does not disclose error behavior, side effects, or what happens if the device/parameter doesn't exist or the value is out of range.

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, front-loaded with purpose, and includes a practical usage hint. The Args section is structured and free of redundant text.

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?

For a simple setter, the description covers the prerequisite and parameter semantics effectively. With an output schema present, it needn't describe return values, and it's sufficiently complete for selecting and invoking the tool, though it doesn't address error cases.

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 description's 'Args' block explains all three parameters with semantic detail that the schema lacks: zero-based indices and the min/max range constraint. Since schema coverage is 0%, this fully compensates for the missing schema descriptions.

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 ('Set'), the target ('a parameter value on a device on the master track'), and explicitly differentiates from sibling tools by specifying the master track. It also references the companion get_master_device_parameters tool, reinforcing its unique scope.

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 provides a specific prerequisite ('Use get_master_device_parameters first') which tells the agent when and how to prepare. However, it does not explicitly contrast with set_device_parameter or set_return_device_parameter, so it lacks explicit alternatives/exclusions.

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