Set mixer track solo

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

Annotations already indicate non-readonly, non-destructive, idempotent, and open-world behavior. The description adds minimal context (meaning of the 'state' parameter) but does not disclose side effects like whether it clears other solos or interacts with mute. No contradictions.

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 concise sentence that front-loads the core purpose. While it could include more detail, it conveys the essential action efficiently without 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?

Given a simple tool with two parameters and an output schema, the description omits information about return values (though output schema may cover it) and potential side effects. It is adequate but not fully comprehensive.

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?

With 0% schema description coverage, the description needs to explain parameters. It partially clarifies 'state' (True solos) but does not explain 'track' (e.g., that it is a zero-based mixer track index). The schema provides a minimum value but no semantic meaning.

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 it solos or unsolos a mixer track, using a verb ('set') and specific resource ('mixer track solo'). It explicitly indicates the meaning of the 'state' parameter, distinguishing it from siblings like fl_set_mixer_mute or fl_clear_mute_solo.

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 offers no guidance on when to use this tool versus alternatives such as fl_solo_tracks (which might solo multiple tracks) or fl_clear_mute_solo. It lacks information about prerequisites or typical use cases.

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