label_silence_regions

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

With no annotations provided, the description carries the full burden and does disclose the key behavioral traits: audio is replaced with silence, the timeline length is unchanged, and labels remain in place. It lacks explicit mention of irreversibility or undo behavior, but the destructive nature is clearly conveyed without contradicting any structured metadata.

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 two short sentences with the main action front-loaded. Every sentence adds useful behavioral information: 'Replace the audio under every label with silence' states the action, and the second sentence clarifies order-independence and timeline preservation.

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 command with no output schema, the description covers the core behavior well: what changes, what does not change, and why order does not matter. Minor ambiguity remains about whether 'every label' means all labels across all tracks, but this is a small gap for such a simple tool.

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 the schema description coverage is 100%, so there are no parameter semantics to clarify. Per baseline for zero-parameter tools, this dimension receives a 4.

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 states a specific verb and resource: 'Replace the audio under every label with silence.' It also distinguishes itself from cut/delete operations by noting the timeline length is preserved and labels stay put, which differentiates it from siblings like label_cut_regions and 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 description makes the tool's behavior clear but does not explicitly say when to use it versus alternatives such as label_cut_regions, label_delete_audio_at, or edit_silence. Usage guidance is implied through the non-shifting, label-preserving behavior, but no alternative is named or excluded.

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