set_track_solo

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

With no annotations, the description carries the full burden of disclosing behavioral side effects. It only restates the action without explaining whether soloing affects other tracks, if it is toggling or absolute, or any prerequisites (e.g., valid track index). This lacks the transparency expected 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, front-loaded with the core purpose, and followed by a clear parameter list. Every line earns its place; there is no filler or wasted words.

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 track-setting tool, the description covers the essential purpose and all parameters. It does not mention return values or prerequisites, but given the simplicity and lack of output schema, the description is sufficiently complete for an agent to select and use it correctly.

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 schema provides only type/title information with no descriptions, so the description must compensate. It explicitly explains track_index, soloed (with default and meaning), and user_prompt (telemetry), covering all three parameters fully and adding meaning beyond the raw schema.

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 states 'Solo or unsolo a track' with a clear verb and resource, and the parameter list clarifies that it sets a boolean solo state. This distinguishes it from sibling tools like set_track_mute or set_track_volume, which control different track properties.

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 use whenever a track needs to be soloed or unsoloed, but it does not explicitly mention when not to use it or contrast it with alternatives like muting. The context is clear from the name and parameters, but no explicit exclusion 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.
