create_audio_track

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

With no annotations, the description carries the full transparency burden, but it fails to disclose post-conditions, selection behavior, or error handling. The only behavioral detail is the 'index' parameter's -1 meaning, which is parameter semantics rather than a general behavioral trait.

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 two concise, well-structured parts: a clear one-sentence purpose followed by a bulleted parameter list. It contains no filler and is easily scannable.

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?

While the purpose and parameters are covered, the description lacks any mention of side effects, return values, or behavior in relation to other track operations (e.g., selection or arrangement). For a simple creation tool, it is adequate but leaves room for additional context that would help an agent fully understand the tool's impact.

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 input schema provides zero descriptions (0% coverage), but the description compensates fully by explaining both parameters: 'index' with its insertion position semantics (including -1 for end of list) and 'user_prompt' for telemetry. This exceeds the schema's information.

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 uses a specific verb (create) and resource (audio track), clearly distinguishing it from sibling 'create_midi_track'. This leaves no ambiguity about the tool's function.

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 is provided about when to use this tool over alternatives like 'create_midi_track' or what conditions should prompt its use. The description only states the action and parameters, offering no contextual or exclusionary information.

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