set_track_crossfader_assign

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

No annotations are present, so the description alone must disclose behavioral traits. It only states it assigns a track to a crossfader side, without mentioning if changes are reversible, permissions required, or side effects on playback or routing.

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 short and front-loaded with the purpose, but it lacks inclusion of other important parameters like track_index and track_type. It is concise but at the cost of completeness, earning a middle score.

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?

Given 4 parameters, no output schema, and no annotations, the description is incomplete. It does not explain what happens after assignment, what the tool returns, or how track_index and track_type affect behavior. Significant gaps remain.

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 must add meaning. It only explains the 'assign' parameter with allowed values ('A', 'B', or 'None'), but ignores the required 'track_index' and optional 'track_type'. This leaves three out of four parameters largely undocumented.

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 assigns a track to a crossfader side, with a specific verb and resource. It distinguishes from the sibling 'set_crossfader' which sets the crossfader position itself. However, it does not mention the required track_index and track_type, slightly reducing clarity.

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 guidance is provided on when to use this tool versus alternatives like set_track_mute or other track assignments. The description implies it is for crossfader assignment but offers no when-not or prerequisite conditions.

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