get_noise_profile

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

No annotations are provided, so the description carries the full burden here. It does disclose the underlying mechanism — 'Sets NoiseReductionEffect's GetProfile flag and runs it' — and relates it to Audacity's dialog button. However, it never explicitly states whether the audio is modified, whether a previous profile is overwritten, or what the tool returns after the call.

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 well structured: purpose first, then the critical precondition, then implementation context. Each sentence earns its place, and the warning is clearly separated and 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, stateful capture tool, the description provides the needed invocation context: selection requirement, relationship to noise_reduction, and the underlying Audacity behavior. It could go further on return values and exact side effects, but it is broadly complete for selecting and calling the 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?

There are zero formal parameters, so the schema is already complete; the baseline is 4. The description adds useful implicit-parameter guidance by telling the agent to ensure the current selection is pure noise of about 0.5-2 seconds before invoking the tool.

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 opens with a specific verb and resource: 'Capture a noise profile from the currently selected audio region.' It also states that this profile is used by the noise_reduction tool, which clearly separates it from the many effect and analysis siblings.

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?

It gives an explicit precondition: 'Select a region of pure noise (e.g. 0.5-2 seconds of silence/background noise) before calling this.' It also explains the profile feeds the noise_reduction tool. It does not discuss when not to call it or name alternatives, but the context is clear enough for correct use.

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