mixer_solo

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

With no annotations, the description carries the full burden, and 'Solo / unsolo / toggle' only hints at mode changes. It does not disclose side effects (e.g., clearing other solos), persistence, or return behavior, and gives no context about what toggling depends on.

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 only three words and front-loads the core behavior without any filler. It is concise almost to a fault, but no sentence is wasted.

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 two-parameter tool, the description plus schema conveys the basic callable surface. However, with no annotations, output schema, or parameter explanations, it leaves the exact solo semantics and track-addressing conventions unstated, making it barely adequate.

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 must compensate. It loosely maps to the solo parameter by suggesting three modes, but it never explicitly says that `solo=true` solos, `solo=false` unsolos, and `solo=null` toggles, nor does it explain what `track` refers to.

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 phrase 'Solo / unsolo / toggle' conveys the action modes and distinguishes three behaviors, but it never explicitly names the resource (mixer track) and relies on the tool name and schema to supply context. It is clearer than a tautology but does not differentiate from sibling tools like channel_solo or mixer_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?

There is no guidance about when to use mixer_solo versus the many related sibling tools (mixer_mute, channel_solo, playlist_solo_track). No context, prerequisites, or exclusions are given, so the agent must infer applicability from the name alone.

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