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

No annotations are provided, so the description carries full burden. It discloses the underlying API call and states removal of tracks with no regions, but does not detail destructiveness, reversibility, or permissions. Adequate but not thorough.

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 three lines with a blank line separating purpose from parameter explanation. Every sentence adds value; no wasted words. Front-loaded with the primary action.

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 cleanup tool with one parameter and an output schema, the description provides sufficient context. It explains the operation and parameter meaning. Could mention return details, but output schema likely covers that.

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 no parameter descriptions (0% coverage). The description fully explains the sole parameter: 'unit_index: Audio unit index (-1 = all AUs).' This adds crucial meaning beyond the schema's title, making the tool easy to invoke correctly.

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 the verb 'Remove empty tracks' and the resource 'from an audio unit (or all AUs)'. It specifies 'removes tracks with no regions', making the purpose unambiguous and distinct from siblings like 'delete_track'.

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 usage context: 'Useful cleanup after deleting regions or editing.' This implies when to use it, though explicit alternatives or when-not-to-use guidance is missing. The context is clear enough for selection.

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