generate_silence

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It conveys the core behavior—filling the selected time range with silence—and the dependency on a prior selection. However, it does not state whether existing audio in the range is overwritten, whether the operation is reversible, or any destructive side effects. That gap matters for an audio-editing mutation tool.

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, each earning its place: the first states the action, the second gives the essential usage prerequisite. No filler or repetition, and the most important information is front-loaded.

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, the description is nearly complete: it names the behavior, the target scope, the prerequisite action, and confirms no parameters are needed. The only minor gap is the lack of an explicit warning that the selected audio will be replaced with silence, which is somewhat implied by 'fills'.

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 is empty, so schema coverage is effectively 100%. The description explicitly says 'Takes no parameters' and clarifies that duration is controlled through select_region instead. This adds useful semantic guidance beyond the empty 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 uses a specific verb and resource: generate silence, and explains that it fills the currently selected time range. This clearly distinguishes it from siblings like generate_tone, generate_noise, and edit_silence, so an agent knows exactly what the tool does and what output to expect.

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 gives an explicit prerequisite: call select_region first to control duration. This is clear, actionable usage guidance. It does not explicitly contrast with alternatives, but for a zero-parameter generation tool the selection-based workflow is the main decision the agent needs to make.

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