get_audio_levels

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

No annotations are provided, but the description only states the output content. It does not disclose whether the operation is a snapshot, requires permissions, or if there are side effects. More behavioral context is needed.

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 a single sentence with no wasted words. The verb and resource are front-loaded, making it immediately clear.

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?

The tool has no parameters and an output schema exists, so return values are covered. The description is sufficient for a simple listing tool, though it could mention scope (all audio inputs) explicitly.

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 no parameters, so schema coverage is 100%. The description adds no parameter info, but baseline for zero params is 4. No additional meaning is necessary.

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 'List audio inputs with mute state and volume (dB)' uses a specific verb ('list') and clearly identifies the resource ('audio inputs') and the attributes returned. This distinguishes it from the sibling 'list_inputs' which likely covers all inputs.

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?

No guidance on when to use this tool versus alternatives like 'list_inputs'. There is no mention of prerequisites, context, or when-not-to-use.

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