mixer_set_pan

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

Provides the valid range for pan, but nothing else. No annotations are present, so the description carries the full burden. Missing details like what happens if pan is out of range or track does not exist. Minimal behavioral disclosure beyond the range.

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?

Single sentence, front-loaded with action and range. No wasted words. Highly efficient.

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 the simplicity of the tool (two parameters, no output schema), the description is mostly adequate. However, it omits details like track indexing and behavioral traits that would help an agent use it correctly without prior knowledge.

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 coverage is 0%, so description must compensate. It adds the range for the pan parameter, which is helpful, but does not clarify what 'track' means (e.g., 0-based or 1-based index). Partial compensation but incomplete.

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?

Description explicitly states the action ('Set mixer track pan') and includes the valid range (-1.0..1.0). Clear verb+resource combination that distinguishes from sibling tools like mixer_set_volume or mixer_set_stereo_separation.

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. Usage is implied by the action name, but no explicit context about when to adjust pan versus other mixer parameters.

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