enable_device

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

With no annotations, the description carries the burden. It specifies zero-based indices and the boolean enabled semantics, which is useful. However, it does not disclose potential side effects (e.g., audio impact), index validation, or whether the track is a session track (vs. return/master), limiting full transparency.

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 compact and well-structured, with a one-line summary followed by a clear Args list. No fluff; every sentence adds value.

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 simple enable/disable tool, the description is adequate but not complete. It lacks clarification on track types (e.g., session vs. return/master), expected error behavior for invalid indices, and whether the device must exist. The presence of an output schema reduces the need for return-value details, but these 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?

The schema has 0% description coverage, but the description fully compensates by defining each parameter: track_index as zero-based, device_index as zero-based, and enabled as boolean with explicit True/False meaning. This adds critical meaning beyond the bare 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 'Enable or disable a device on a track' with a specific verb and resource, and the Args section reinforces the action. This distinguishes it from siblings like set_device_parameter, which focus on parameter changes rather than device on/off state.

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 usage is implied by the name and description: use this when you want to enable or disable a device. However, it does not explicitly mention alternatives (e.g., set_device_parameter) or when not to use it, leaving the agent to infer when this tool is preferred.

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