A3.6/5.0
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action without detailing side effects (e.g., whether it impacts system volume, if it toggles or sets state, or any persistence). This is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: one sentence for purpose, one for the argument. It is front-loaded and avoids unnecessary details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (single boolean parameter), the description covers the essential purpose and parameter meaning. It lacks any note on side effects or when to use, but for a mute function, it may be adequate; however, it could mention that it applies to Apple Music playback only, which is already stated. It is reasonably complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description explicitly explains the 'muted' parameter: True to mute, False to unmute, adding clarity beyond the raw schema type. Since schema coverage is 0%, this description is essential and effective.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: muting or unmuting Apple Music audio playback. It uses a specific verb (mute/unmute) and targets a specific resource (Apple Music audio playback), distinguishing it from volume control tools like itunes_set_volume.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 such as itunes_set_volume or itunes_set_device_volume. It implies usage for muting but does not explain exclusions or preferability.

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