set_track_volume

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

The description discloses the valid volume range (0.0 to 1.0) and default (0.85), adding behavioral context. However, it does not mention side effects, atomicity, or whether changes are undoable. With no annotations, the description partially compensates but is not thorough.

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?

Descriptive yet concise: two sentences and a parameter list. No fluff, front-loaded with the main action, and every sentence is valuable.

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 setter with two parameters and no output schema, the description is largely complete. It lacks detail on whether track_index is 0-based or 1-based, which is a minor gap.

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%, so the description fully carries the burden. It explicitly explains both parameters: track_index is 'the index of the track' and volume explains range and default. This adds complete meaning beyond the schema.

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 the volume of a track.' This is a specific verb-resource combination that distinguishes it from sibling tools like set_track_pan or 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 usage guidelines provided. The description does not indicate when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions.

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