create_audio_track

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the creation action and provides no information about side effects, permissions, or what happens to the track after creation (e.g., whether it becomes selected or affects playback). This is insufficient for a creation 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 extremely concise: two short sentences, with the action front-loaded. Every word serves a purpose—no fluff or redundancy. It achieves maximum information density for the limited scope.

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?

Given the complexity of a creation tool with one parameter and an output schema (not described), the description is too minimal. It does not mention return values, prerequisites, or how this tool fits among siblings. The agent may need more context to use it correctly, especially when there are many similar track-creation tools.

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 has 0% description coverage, so the description must add meaning. It explains the index parameter's typical usage (-1 for append), which helps, but does not explain other possible values or behavior (e.g., inserting at a given index). It adds some value but is not comprehensive.

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 'Create a new audio track,' which is a specific verb and resource. It distinguishes from sibling tools like create_midi_track by specifying 'audio,' so the agent knows exactly what type of track to create.

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?

The description provides basic usage guidance for the index parameter ('Use index=-1 to append at the end'), but lacks explicit when-to-use or when-not-to-use versus alternatives like create_midi_track or create_midi_track_with_instrument. It implies context but does not exclude other tools.

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