set_track_pan

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

Beyond the annotations (destructiveHint: false), the description adds only the pan range. It does not disclose whether setting pan affects automation, requires specific track types, or has latency implications. For a mutation tool, this is insufficient behavioral detail.

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 at a single sentence, which is efficient but sacrifices necessary detail. It front-loads the action and range, but the lack of structure (e.g., separate sections for parameters) reduces clarity for an agent.

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 and sibling tools are numerous, the description should address the return value (e.g., confirmation message) and any prerequisites (e.g., track must exist). The current description leaves the agent guessing about completion tokens or error handling.

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 adds semantic value for the 'pan' parameter by specifying its range (-1.0 to 1.0) and mapping (left to right). However, the 'track_index' parameter receives no explanation whatsoever, and with 0% schema coverage, this is a significant gap.

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 ('Set') and the resource ('track panning') with the valid range (-1.0 to 1.0), making the purpose unambiguous. It effectively distinguishes this tool from siblings like set_track_volume or set_track_mute by specifying the exact parameter being controlled.

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?

No guidance is provided on when to use this tool versus alternatives such as other set_track_* tools, or whether it should be used in conjunction with other operations. The description does not mention prerequisites (e.g., track must exist) or suggest appropriate contexts.

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