set_track

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

No annotations are provided, so the description carries the full behavioral burden, yet it only implies mutation via 'Change'. It never states whether changes apply in real time, are undoable, require the track to be armed, or that omitted fields are left unchanged (a hint appears only for sends). 'Track properties' and track_index resolution semantics are left unstated.

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?

Tight and front-loaded: the purpose leads, then a compact spec list of ranges. Every clause earns its place, though 'about 0.025 per dB near the top' is somewhat trivia-heavy for a tool with six undocumented parameters.

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 an 11-parameter mutation tool with zero annotations and no output schema, coverage is thin: only 4-5 parameters get semantics, no usage context is given, and the effect of omitted fields is unspecified. An agent could call it but might misuse or under-specify arguments.

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% across 11 parameters, so description must compensate. It does add valuable semantics for volume (0.0-1.0, dB mapping), pan (-1..1), color_index (0-69), and sends (per return track, None leaves unchanged), but arm, mute, solo, name, kind, and monitoring are entirely undocumented in both schema and description.

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?

States a clear verb+resource ('Change track properties'), which is enough for an agent to know it mutates a track. However, it doesn't differentiate from siblings like set_clip, set_routing, or set_device_parameters beyond the resource name, so an agent must infer scope from the tool name alone.

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 when-to-use, when-not-to-use, or alternative guidance is given. The description never mentions get_track_info as the read counterpart or set_routing for routing changes, so the agent gets no routing signal among the many sibling mutation tools.

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