mixer_set_color

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

No annotations provided. The description only states the action without disclosing any side effects, error behavior, or requirements such as track existence or color validation.

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?

Very concise single sentence that quickly conveys the core purpose. Front-loaded with verb and resource. Could be slightly more detailed but avoids unnecessary text.

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?

Minimal tool with two required params and no output schema, but description does not explain valid track indices, error handling, or behavior when color format is invalid. Lacks completeness for reliable agent use.

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?

Adds clarity for the 'color' parameter by specifying accepted formats ('#RRGGBB' or 'rgb(r,g,b)'). However, no additional meaning for the 'track' parameter beyond its schema type (integer). With 0% schema description coverage, partial improvement.

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?

Clearly states the action ('Set'), resource ('mixer track color'), and specifies accepted color formats. Unambiguous and distinct from sibling tools that set other mixer properties.

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 on when to use this tool versus alternatives like 'channel_set_color' for channel colors. Does not mention prerequisites or conditions.

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