set_track_solo

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

The term 'Toggles' is misleading because the parameter sets solo to a specific boolean value, not inverts an existing state. With no annotations, the description fails to disclose side effects, prerequisites (e.g., track must exist), or error behavior.

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 very short (one sentence) and front-loaded, but it sacrifices necessary detail for brevity. It could be more accurate and informative without adding much length.

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?

Despite having an output schema, the description provides no context on return values or success indicators. It also lacks information about required preconditions (e.g., track existence) or constraints. The tool's complexity is low, but the description remains incomplete.

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 explains the 'solo' parameter well but leaves 'track_index' completely undefined—no indication of valid range, required format, or meaning. Only one of two parameters gains meaning from the description.

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 (toggles solo status) and the resource (track), and the parenthetical clarifies the mapping for the boolean parameter. It distinguishes itself from siblings like set_track_mute by specifying 'solo' specifically.

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 like set_track_mute or set_track_volume. The context of toggling versus setting is implied but not explicitly clarified, and no when-not-to-use scenarios are mentioned.

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