set_input_audio_tracks

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

With no annotations, the description carries full burden. It fails to disclose whether the operation replaces or merges existing track assignments, and does not mention errors, idempotency, or effects on unspecified tracks. This is a significant gap for a mutation 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, front-loaded with the purpose, and uses a clear Args structure. Every element earns its place with no fluff.

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?

Despite good parameter documentation, this is a mutation with no annotations and no output schema. The ambiguous effect on unspecified tracks (replace vs. merge) creates a significant completeness gap for an agent to use it correctly.

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 description adds substantive meaning beyond the schema: it specifies input_name as 'Name of the input' and audio_tracks with a concrete example and track range (1-6). This compensates well for the 0% schema coverage.

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 action ('Set') and the resource ('audio mixer tracks an input is routed to'), making it distinct from sibling tools like get_input_audio_tracks. It is specific and 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?

Usage is implied by the setter nature, but there is no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. The context suggests it is for configuring audio routing, but no alternatives are named.

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