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

No annotations are provided, so the description carries full burden for behavioral disclosure. While 'Get' implies a read operation, it doesn't specify whether this requires authentication, has rate limits, returns numeric values or percentages, or if it's device-specific. For a tool with zero annotation coverage, this leaves significant behavioral gaps.

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 perfectly concise at just one sentence: 'Get current music/audio volume level'. Every word earns its place - 'Get' (action), 'current' (temporal context), 'music/audio' (domain), 'volume level' (resource). No wasted words or unnecessary elaboration.

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 read operation with no parameters and no output schema, the description is minimally adequate. It states what the tool does but doesn't provide context about return format, error conditions, or how it relates to sibling volume/mute/status tools. Given the lack of annotations and output schema, more context would be helpful but isn't critically missing.

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 tool has zero parameters, and schema description coverage is 100%. The description appropriately doesn't waste space discussing non-existent parameters. A baseline of 4 is appropriate since there are no parameters to document, and the description correctly focuses on the tool's purpose rather than parameter details.

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's purpose: 'Get current music/audio volume level'. It uses a specific verb ('Get') and resource ('volume level'), and the qualifier 'current' adds useful context. However, it doesn't explicitly distinguish this from sibling tools like 'getAudioStatus' or 'getStatus' which might also provide volume information, preventing a perfect score.

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. With many sibling tools like 'getAudioStatus', 'getStatus', 'getMuteStatus', and 'setVolume', there's no indication of when this specific volume query is appropriate versus broader status checks or related operations.

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