mixer_group_volume

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

No annotations are provided, so the description carries the behavioral transparency burden. It usefully discloses the accepted dB range (-80 .. +10) and target format (path or {guid}), but does not mention side effects, error behavior, or what result the agent should expect.

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 compact and front-loaded: the operation is stated in the first line, followed by a minimal Args block. Every sentence adds value and there is no filler.

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 simple two-parameter setter with no output schema, the description covers the essential invocation details: what to set, the target format, and the value range. It is slightly incomplete only in not addressing expected return or alternative tool selection, but overall sufficient.

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?

Schema description coverage is 0%, but the description compensates by explaining target as 'Group path or {guid}' and db as 'Volume in decibels' with an explicit range. This adds practical meaning beyond the schema's bare type and 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 explicitly states the operation: 'Set a mixer group's volume, in dB (-80 .. +10).' This uses a specific verb and resource, and clearly distinguishes it from sibling tools like mixer_master_volume and vca_volume by targeting mixer groups.

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 provides no guidance on when to use this tool versus alternatives, such as mixer_master_volume or vca_volume. It only lists arguments, with no exclusions, prerequisites, or selection context.

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