mute_audio

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

The annotations already indicate this is a mutating operation (readOnlyHint=false) and non-destructive. The description adds the target scope ('master audio channel') and the dual mute/unmute behavior, but does not clarify edge cases such as whether it sets an absolute state or toggles, or what happens when called repeatedly.

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, front-loaded sentence with no filler. Every word contributes to the tool's purpose and parameter meaning.

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 one-boolean-parameter audio tool, the description is largely complete: it names the action, the target channel, and implies the parameter semantics. The main omission is explicit true/false mapping, but that is easily inferred from the schema and description.

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?

With 0% schema description coverage, the description carries the burden of explaining the 'muted' boolean. 'Mute or unmute the master audio channel' strongly implies the boolean selects between muted and unmuted states, adding meaning beyond the bare schema title.

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 specific verb pair ('Mute or unmute') and a clear resource ('the master audio channel'), which unambiguously identifies the operation. It is also easily distinguished from sibling tools like set_volume, volume_up, and audio_devices.

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 implies the tool is for muting or unmuting the master audio output, but it provides no explicit when-to-use guidance or comparison with alternatives such as set_volume or volume_down. The intended use is reasonably inferable, but there is no exclusionary guidance.

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