get_master_device_parameters

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

With no annotations, the description must fully disclose behavioral traits. It only says 'Get all parameters' and describes the argument, but does not mention that this is a read-only operation, what the return structure looks like, possible errors, or side effects. The output schema may cover return format, but the description itself adds little behavioral context.

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 extremely concise, with only two sentences plus a docstring-style argument description. It is front-loaded with the purpose, and every word contributes meaning. No fluff.

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 that this is a simple getter with a single parameter and an output schema exists (so return details are covered), the description is nearly complete. It lacks only a note about potential errors or how the device is identified beyond the index, but that is a minor gap for such a straightforward 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 only parameter, device_index, is clearly explained as a zero-based index within the master track's device chain. This adds critical context beyond the bare integer type in the schema, which has 0% description coverage, and fully compensates for the lack of schema-described parameters.

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 action ('Get') and the resource ('all parameters of a device on the master track'), which differentiates it from sibling tools like get_device_parameters or get_return_device_parameters by specifying the master track. However, it does not explicitly name alternatives or explicitly state that this is only for the master track, so it falls short of a perfect 5.

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 intended use is implied by the phrase 'on the master track', but there is no explicit guidance about when to use this tool versus alternatives such as get_device_parameters or get_return_device_parameters. No exclusions or alternative recommendations are provided.

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