set_track_pan

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

With no annotations, the description must disclose behavioral traits, and it does so effectively. It reveals that pan values are clipped to range and that track_index is ignored for master tracks. These are valuable runtime behaviors not captured by the schema. However, it doesn't mention what happens when an invalid track_index is provided or whether the operation is reversible.

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 well-structured. It opens with a clear one-sentence purpose, followed by a parameter list with meaningful explanations. Every sentence adds value and there is no redundant information.

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 low complexity of this simple setter tool, the description covers all necessary aspects: purpose, parameter semantics, and key behavioral details like clipping and master track handling. No output schema is present, but the return value is not critical for a set operation.

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?

Schema description coverage is 0%, so the description alone carries the burden of explaining parameters. It thoroughly describes each parameter: pan's range and clipping behavior, track_kind's allowed values and default, and track_index's special behavior for master tracks. This fully compensates for the schema's lack of 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 states 'Set a track's stereo pan position' with a specific verb and resource. It distinguishes itself from sibling tools like set_track_volume and set_track_mute by focusing on pan, making the purpose unambiguous.

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 does not explicitly state when to use this tool versus alternatives like set_track_volume or set_track_solo. However, the parameter details (especially track_kind) imply usage contexts such as adjusting master vs. regular tracks. No exclusions or alternative guidance is provided.

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