set_device_enabled

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

Annotations indicate idempotentHint=true and destructiveHint=false. Description adds behavioral detail: true turns device on, false bypasses while preserving device and parameter values, and clarifies it changes audible signal flow but not clip content. No contradictions.

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?

Two paragraphs, well-structured. First sentence is a clear summary, followed by a bullet-style explanation. No wasted words.

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 tool's simplicity (boolean toggle) and that an output schema exists, the description fully covers behavior, parameter effects, and alternatives. No gaps.

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?

Input schema has 100% coverage with descriptions. Description adds extra meaning by explaining the effect of true/false on the device (bypassing preserves device and parameter values), going beyond the schema's simple 'True turns on; false turns off.'

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?

Clearly states 'Enable or bypass one device on a regular track.' Uses specific verb+resource and distinguishes from siblings like set_track_mute and set_device_parameter.

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?

Explicitly tells when to use this tool vs alternatives: 'Use set_track_mute to silence the whole track, or set_device_parameter to change one control.' Provides context on what this tool does (changes audible signal flow but not clip content).

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