set_track_solo

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

No annotations are provided, so the description carries the full burden. It only states the basic operation without disclosing side effects (e.g., whether soloing a track affects other tracks), error behavior for invalid track_index, or any state changes beyond the solo flag. This is a significant gap for a mutating 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 concise and well-structured, with a brief opening sentence and a clear parameter list. No wasted words, and it is easy to scan.

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 setter tool, the description covers the essential parameters and purpose. However, it lacks usage context and behavioral details that an agent would need to use the tool safely, such as whether solo mutates other tracks or what happens with invalid indices. Given there is no output schema or annotations, the description is minimally viable but 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?

The input schema has no descriptions (0% coverage). The description compensates by explaining both parameters: 'track_index: The index of the track' and 'solo: True to solo, False to unsolo'. This clarifies the meaning and valid boolean values, adding value beyond the 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 clearly states the tool's action: 'Set the solo state of a track.' It uses a specific verb ('Set') and resource ('solo state of a track'), which differentiates it from sibling tools like set_track_mute or set_track_arm. The purpose is unambiguous.

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. There is no mention of prerequisites, context, or exclusions. The agent has no information to decide between solo, mute, or arm except from the tool name.

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