sonos_pause

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

No annotations are provided, so the description fully carries the burden. It discloses that pause maintains current position in track/queue (for quick resume) and affects the entire group if the device is grouped. It does not mention error conditions or other side effects, but for a simple pause action, this is reasonably transparent.

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 sentences, no wasted words. The first sentence states the core purpose, the second adds key behavioral details. Perfectly front-loaded and concise.

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 (one parameter, no output schema), the description covers purpose, behavior (maintains position), and group effect. Nothing essential is missing for an AI agent to correctly select and invoke this tool.

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 coverage is 100% with one parameter (deviceId) described as 'Room name, UUID, or IP address'. The description adds no additional meaning to the parameter. Baseline is 3 because schema already documents the parameter sufficiently.

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 'Pause playback on a Sonos device.' It uses a specific verb ('pause') and resource ('playback on a Sonos device'). It distinguishes from siblings like sonos_stop by explicitly noting that it maintains current position for quick resume, and from sonos_play by being the opposite action.

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 implies when to use this tool (to temporarily pause without losing position) and mentions group behavior (affects entire group). However, it does not explicitly state when not to use it or compare it to sonos_stop, which would make guidelines clearer.

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