set_track_pan

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

No annotations are provided, and the description adds little behavioral detail. It merely states the action and enumerates parameters. It does not disclose potential side effects (e.g., overwriting existing pan, affecting automation), validation constraints, required permissions, or error conditions. This leaves a significant transparency gap for a mutation tool.

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 compact and front-loaded with the main action, followed by a concise parameter list. Every sentence adds value, though the parameter explanations could arguably be moved to the schema. No unnecessary words or redundancy.

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 parameter setter with no output schema, the description covers purpose and key parameter semantics. It is missing only minor details like whether track_index is zero-based and any interaction with playback or automation. Overall, it is adequately complete for the tool's simplicity.

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?

While the schema only lists types, the description enriches each parameter: track_index is defined as 'the index of the track,' pan is given a meaningful range (-1.0 to 1.0 with 0.0 center), and user_prompt is explained as telemetry. This significantly helps the agent use the tool correctly, compensating for the 0% schema coverage.

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 opens with a direct, specific action: 'Set a track's mixer pan.' This clearly names the resource (track) and the property (pan), distinguishing it from sibling tools like set_track_volume or set_track_mute.

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 implies usage by its name and action, but provides no explicit guidance on when to choose this over alternatives, nor any exclusions or prerequisites. The parameter list gives some context (e.g., pan range), but there is no statement like 'use this to balance a track in the stereo field.' Thus, usage is mostly implied.

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