create_audio_track

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the creation action and explains the index parameter, without mentioning side effects, prerequisites, or behavior in edge cases (e.g., invalid index or if a track already exists at that position).

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 exceptionally concise, front-loading the primary purpose in the first sentence and followed by a brief, necessary parameter explanation. Every sentence earns its place with no filler or redundancy.

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?

For a simple one-parameter creation tool, the description covers the core purpose and parameter semantics, and an output schema exists. However, it lacks any comparison to sibling tools or mention of behavioral constraints, making it moderately complete but not fully self-sufficient.

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 schema provides only the type and default for 'index', while the description adds crucial meaning by explaining that it is the insertion position and that -1 appends to the end. This significantly compensates for the lack of schema-level descriptions.

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") with a clear resource ("audio track") and context ("in the session"). This clearly distinguishes it from sibling tools like create_midi_track and create_session_audio_clip, making the purpose 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?

No guidance is provided on when to use this tool versus alternatives such as create_midi_track. The description only states the action and parameter, leaving the agent to infer usage context without explicit exclusions or alternative recommendations.

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