Set Monitor Output Level

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

Annotations already indicate this is non-read-only, idempotent, and non-destructive. The description adds valuable behavioral context by explaining the dual unit systems (linear vs. dB) and the unity-gain mapping (0 dB = 0.75 linear), which goes beyond what annotations or schema provide. It does not mention preconditions like connection state, but the added information is meaningful.

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 two sentences long, front-loads the action and target, and includes only essential information. It avoids repeating schema details verbatim and contains 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 strong annotation coverage and no output schema, the description is largely complete. It provides the target, supported units, and a key conversion fact. It would be slightly more complete with explicit sibling differentiation or edge-case behavior, but that is covered under other dimensions.

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 coverage is 100%, so the baseline is 3. The description adds the key cross-unit equivalence (0 dB = 0.75 linear) that is not present in the schema, improving the agent's understanding of how to interpret the 'value' parameter in either unit.

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 ('Set') with an explicit resource ('monitor output fader level on the X32/M32 mixer'), clearly distinguishing it from sibling tools like channel_set_volume, bus_set_volume, and main_set_volume. It also mentions the supported unit formats, adding scope without ambiguity.

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 clearly implies when to use this tool—when the target is the monitor output fader—but it does not explicitly contrast it with alternative tools or state when not to use it. This is clear context without exclusions, but not full alternative guidance.

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