mcp_opendaw_set_track_volume

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

Despite lacking annotations, the description discloses the mapping function (powerByCenter), range (-96 to +6 dB), and the 0 dB mapping to 0.768. This adds some behavioral awareness, but does not address side effects, permissions, or reversibility.

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?

Three short sentences, each adding distinct information: action, mapping, range and 0 dB reference. No filler, but could be more concise by merging technical details.

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?

With an output schema present, return value details are covered. However, with no annotations, the description misses prerequisites (e.g., does the unit need to exist?) and behavioral constraints, leaving gaps for a mutation 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?

With 0% schema coverage, the description should explain both parameters. It implicitly describes volume_db (dB value) but does not explicitly mention unit_index's role. The mapping details add context for volume_db but not enough for completely clear parameter use.

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 clearly states the action ('Set volume of an audio unit in dB') and provides technical details like range and mapping, but the term 'audio unit' slightly diverges from the tool name's 'track', and it doesn't explicitly distinguish from sibling set tools (e.g., set_track_mute).

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 vs alternatives like set_track_panning or set_track_mute. The description only provides internal implementation details (VolumeMapper), not usage context.

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