Delete unused regions

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

With no annotations, the description carries the full burden and does well on the most important point: it defines the destructive boundary by telling the agent that the underlying audio files stay in the package. It omits irreversibility/undo and any auth or confirmation requirement, so it stops short of full behavioral coverage.

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?

Two short sentences, front-loaded with the action and its scope, followed immediately by the side-effect clarification. Nothing is padded or repeated.

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 one-parameter, no-output-schema tool, the description supplies the operation, its scope, and the key side effect an agent must know before calling it. The only real gap is the absence of any note on reversibility, which matters for an unannotated destructive operation.

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?

Only one parameter exists and schema description coverage is 100%, so the schema already explains the .audium project path. The description adds no format or path guidance beyond that, matching the baseline for a fully documented single parameter.

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?

States a specific verb ('Deletes') and a precisely bounded resource ('every region that has no clip on the timeline'), which cleanly separates it from sibling mutators like create_region, set_region, and remove_clip. The parenthetical GUI mapping pins the intent unambiguously.

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 condition under which regions are targeted is explicit ('no clip on the timeline'), but there is no guidance on when to run this versus leaving regions alone, nor any prerequisite or safety note. Usable but inferred rather than stated.

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