create_audio_track

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

The annotation destructiveHint: false indicates non-destructive behavior. The description adds that index -1 appends at the end, providing behavioral context for the default. However, it does not describe behavior for other index values.

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 with no wasted words. One sentence plus a clarifying clause is ideal for such a simple tool.

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 single-parameter tool with an output schema, the description provides essential context about the index parameter. It is nearly complete, lacking only explicit behavior for non-default indices.

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?

With 0% schema description coverage, the description adds meaning for the index parameter by explaining that -1 appends. This is helpful but does not cover other possible integer values.

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 it creates an audio track. Although it does not explicitly differentiate from sibling tools like create_midi_track, the tool name and description together make the purpose clear.

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 only provides a detail about the index parameter but lacks any guidance on when to use this tool versus alternatives like create_midi_track. No when/when-not or explicit context is given.

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