set_track_volume

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

With no annotations provided, the description carries the full burden. It discloses important behavioral details: the 0.0-1.0 scale, 0.85 unity, clipping to range, and track_kind behavior. It does not mention return values or error handling, but covers the essential mutation semantics.

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 concise and front-loaded with the core action, followed by a well-organized parameter list. Every sentence provides useful information without fluff or redundancy.

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 setter tool with no output schema and no annotations, the description covers the key semantics: scale, clipping, and track kind distinctions. It could be more complete by stating what happens on errors or what the return value is, but the provided details are sufficient for correct invocation.

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 compensates fully. It explains each parameter's meaning, including the default track_kind, the unity gain value, and that track_index is ignored for master. This adds significant context beyond the schema's bare types and defaults.

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 'Set a track's volume' with a specific verb and resource. It distinguishes this tool from siblings like set_track_pan, set_track_solo, and set_track_mute by focusing solely on volume adjustment.

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?

It provides clear context by explaining the normalized scale and noting that track_index is ignored for master. While it doesn't explicitly mention alternatives or when-not-to-use, the volume-specific purpose makes the intended use obvious.

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