Play built-in audio

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

No annotations are provided, so the description carries the full burden. It clearly says the action plays a local fixed audio track, but it does not disclose whether playback blocks, how long the sound lasts, or whether it interrupts other audio. That is a moderate gap for a side-effect-producing tool.

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 a single front-loaded sentence with no wasted words. It communicates the core action, the resource, and the scope efficiently.

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 trivial single-parameter tool with a one-value enum, the description plus schema provide enough to invoke correctly: pass audio='zako'. However, it omits any detail about return behavior or side effects and does not connect to sibling listing tools, so it is complete only because the operation is minimal.

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 description coverage is 0%, and the description never mentions the 'audio' parameter. The phrase 'one fixed... track' weakly implies that the enum value 'zako' is the only preset available, but the description adds almost no semantic meaning beyond the schema's enum.

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 states a specific verb ('Play'), a resource ('fixed, built-in audio track'), and scope ('on this computer'). The explicit 'one fixed' characteristic distinguishes it from siblings like notify_list_audio, which likely enumerate available tracks.

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 explicit when-to-use or when-not-to-use guidance. 'One fixed... track' implies this is for the single built-in audio option and not for selecting among multiple tracks, but it never names alternatives or exclusions.

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