set_track_volume

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

With no annotations, the description carries the full burden. It provides useful context about the volume scale and default (0.0 silent, 1.0 unity gain, 0.85 default), which aids understanding. However, it does not disclose whether the change is immediate, undoable, or has side effects, which is a notable gap for a mutation tool.

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 efficiently structured with a one-line purpose followed by a parameter list. Every sentence earns its place, and it is immediately clear what the tool does and what the parameters mean without wasted words.

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 covers the essential semantics: purpose and parameter details. It lacks error behavior or how to obtain track indices, but these are beyond the minimal requirements for this tool type, making it fairly complete.

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 0%, so the description compensates well. It explains track_index as 'the index of the track' and volume with a clear range and default, making the parameters understandable. Track_index could be more specific about indexing scheme, but the volume detail is strong.

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 tool sets the volume of a track with a specific verb and resource. It distinguishes from sibling tools like set_master_volume and set_return_volume by explicitly targeting regular tracks, even without naming alternatives.

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 explicit guidance is given on when to use this tool versus alternatives such as set_master_volume or set_send_level. Usage is implied by the track resource, but there are no when-to-use or when-not-to-use conditions, making this minimally adequate.

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