label_delete_regions

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

With no annotations provided, the description carries the full disclosure burden and does it well. It explicitly states the operation is destructive ('Delete the audio'), explains that gaps are closed, discloses the last-to-first processing strategy, and warns that the timeline shifts and label data should be re-read afterward.

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 concise and well-structured: the main action is stated first, followed by the essential processing-order detail and a practical verification step. Every sentence adds value, and there is no redundant or filler content.

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 zero-parameter tool with no output schema and no annotations, the description is complete. It tells the agent what will happen, how the operation is executed, and what to do after invocation ('Re-read label_list afterwards'), leaving no critical ambiguity about the tool's effect or side effects.

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 tool has zero parameters and 100% schema description coverage, so there are no parameter semantics to clarify. The baseline of 4 applies because the description adds no unnecessary detail and the absence of parameters is fully reflected in the schema.

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 names a clear action and resource: deleting audio under every label and closing the resulting gaps. It is specific enough to be understood, but it does not explicitly differentiate itself from similar label/region tools like label_cut_regions or label_delete_audio_at.

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 intended use is implied: delete all audio regions marked by labels and close the gaps. However, it does not state when to choose this tool over alternatives such as label_cut_regions or edit_delete, nor does it mention any prerequisites or exclusions.

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