mix_set

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

No annotations, so description carries the burden; it discloses partial update behavior and pan range, but does not specify volume_db range/units beyond 'dB' or how mute/solo booleans behave.

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?

One tight sentence with the action and key constraints front-loaded; no filler.

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?

Adequate for a simple setter: identifies target, parameters, and partial-update semantics, but lacks a few details like accepted volume_db range or behavior when no optional fields are supplied.

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 has no descriptions; description names every parameter and gives units for volume and pan range, though it leaves volume_db range and mute/solo semantics implicit.

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?

States a specific verb 'Set' and resource 'track volume, pan, mute, solo' with track_id, distinguishing it from track creation/removal/routing siblings.

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?

Clear that it is for adjusting existing track mix parameters and that only changed fields need be passed, but it does not name alternative tools or explicit when-not-to-use.

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