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 usefully discloses the unit scale and practical range (0 = unity gain, -inf to +12), which is real behavioral context, but says nothing about whether this overwrites automation, whether it is undoable, or what it returns.

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?

Front-loaded single sentence followed by a short Args note; no filler. The 'Args:' scaffolding is slightly redundant for a two-parameter tool but harmless.

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?

Annotations are absent and there is no output schema, so the bar is higher, but for a simple two-param setter the description plus schema is nearly sufficient. The main gap is the unexplained track_index and any statement of side effects.

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 must compensate. It documents volume_db well (unit, unity point, range) but leaves track_index entirely unexplained, covering only half the parameters.

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?

Specific verb+resource: setting a track's volume in decibels. The phrase 'of a track' implicitly separates it from siblings like set_send_volume and set_item_volume, though no sibling is named outright.

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 indication of when to use this versus set_send_volume, set_item_volume, or envelope-based automation. Use is inferable from the name only; the description offers no context or exclusions.

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