garageband_set_track

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

With no annotations, the description carries the full burden of behavioral disclosure. It states the tool sets controls but does not explain side effects (e.g., whether changes are immediate or require confirmation), error handling, or constraints like which controls can be set simultaneously. This lack of detail hinders safe invocation.

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 a single, efficient sentence that conveys the core purpose. However, it could be slightly more structured by separating the control list or adding usage hints without increasing word count significantly.

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 the absence of annotations, output schema, and param descriptions (0% coverage), the description is insufficiently complete. It does not explain return values, error states, or how multiple parameters interact. An agent would likely need additional context to use this tool correctly.

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 lists the control types (mute, solo, volume, pan, name) but does not explain the meaning or expected format of parameters like index, max_depth, or the varied types (e.g., volume accepts string, number, integer). The description adds marginal value over raw schema.

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 a visible GarageBand track header control (mute, solo, volume, pan, or visible track name). It is specific about the resource and action, but does not differentiate from sibling tools that also modify UI elements, such as garageband_set_ui_value or garageband_set_smart_control.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or when not to use it. Without exclusions or context, an agent may misuse the tool.

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