set_track_solo

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It only states 'Solo or unsolo a track,' which implies state mutation but does not elaborate on side effects (e.g., affecting other tracks' routing or playback). It lacks details about permissions, reversibility, or what happens to the track's previous solo state.

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 no superfluous words. It is front-loaded and concise. However, it could benefit from a brief additional clause explaining the two parameters, given the lack of parameter documentation in the schema.

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 toggle operation, the description is minimally adequate. The presence of an output schema reduces the need to describe return values. However, given the low parameter coverage and lack of behavioral context, the description is not fully complete. It provides the essential purpose but leaves gaps in usage details.

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%. The description does not explain the meaning or expected values of track_index or solo. Without this, the agent must infer from the schema alone. The description adds no value over the parameter names and types.

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 tool's function: to solo or unsolo a track. The verb 'solo or unsolo' is informal but specific, and the resource 'track' is identified. It distinguishes well from sibling tools like set_track_mute or set_track_volume. However, it could be more precise by mentioning the track_index parameter.

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 provides no guidance on when to use this tool versus alternatives (e.g., when to solo vs mute). It does not mention prerequisites, context of use, or exclusions. The agent receives no comparative information beyond the bare action.

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