mcp_opendaw_create_audio_bus

Create an auxiliary audio bus with its own audio unit and track, returning the new bus index for routing.

Instructions

Create a new audio bus (aux bus) with its own audio unit and track.

Follows the upstream AudioBusFactory.createAudioBus pattern: creates AudioUnitBox (Aux) + AudioBusBox + TrackBox, wires them together. Uses separate editing.modify() blocks — pointer refer() inside box constructor fails due to deferred pointer update resolution.

name: Bus label.

Returns the new bus index.

Behavior4/5

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

Since no annotations are provided, the description must fully convey behavioral traits. It discloses that the tool creates multiple internal boxes (AudioUnitBox, AudioBusBox, TrackBox) and wires them, and notes a specific failure scenario with pointer refer() and deferred pointer update resolution. This adds valuable context about side effects and constraints beyond a simple 'create' call.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description starts with a clear summary sentence, which is good. However, it then includes a paragraph of internal implementation details that may not be essential for an agent's decision to invoke the tool. This adds length without significantly aiding selection or invocation, making it less concise than ideal.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema, return values are not needed. The description covers the internal pattern and a known failure case, providing implementation-level completeness. However, it lacks information about idempotency, maximum bus limits, or if the operation can be undone. For a creation tool, some additional context about side effects would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description must add meaning. It states 'name: Bus label' which clarifies the purpose of the 'name' parameter beyond the schema's title. However, no additional constraints, format, or usage tips are provided; the explanation is minimal.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Create a new audio bus (aux bus) with its own audio unit and track.' It uses a specific verb 'create' and a clear resource 'audio bus', distinguishing it from sibling creation tools like create_audio_track or create_send.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives. The description focuses on internal implementation details (e.g., AudioBusFactory pattern, pointer refer() failure) rather than usage context or conditions. It does not explain when creating an audio bus is appropriate or what prerequisites are needed.

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