load_device_to_master

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

The description adds context beyond the destructiveHint annotation by stating it loads onto the master track and gives an example. However, it does not disclose potential side effects (e.g., replacing existing devices, impact on routing) or any prerequisites. The annotation is not contradicted.

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 a single sentence with an example, making it concise and front-loaded. It wastes no words, but it could be more impactful by including parameter guidance without adding length.

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 an output schema exists (reducing the need to explain return values), the description covers the basic purpose but leaves the critical parameter undocumented. For a simple tool, the description is not fully self-sufficient.

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 sole parameter item_uri is left unexplained in both the schema (0% coverage) and the description. Since the description does not clarify what format or type of URI is expected (e.g., browser path, device ID), the agent cannot infer how to populate this parameter correctly.

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 verb 'load', the resource 'device/effect from the browser onto the Master/Main track', and provides a concrete example (limiter for mastering). It distinguishes from siblings like load_device_to_return and load_instrument_or_effect by specifying the target track.

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 gives a clear use case (mastering, e.g., limiter) and implies when to use this tool (when adding a device to the master track). However, it does not explicitly mention when not to use it or point to alternative tools like load_instrument_or_effect for non-master tracks.

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