audio_trigger_active_playlist

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

With no annotations provided, the description carries full burden. It states the tool will 'trigger' and 'restart from beginning', which implies a state-changing operation, but doesn't disclose behavioral aspects like whether this requires specific permissions, what happens if no playlist is active, or if there are side effects on other audio operations.

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, efficient sentence that immediately states the tool's purpose and effect without unnecessary words. Every element ('Trigger', 'active audio playlist', 'restart from beginning') contributes directly to understanding the tool's function.

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 zero-parameter tool with no output schema, the description adequately explains what the tool does. However, as a state-changing operation with no annotations, it should ideally mention more about behavioral context (e.g., what 'active' means, confirmation of success, or error conditions). The completeness is minimal but viable.

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 with 100% schema description coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the tool's effect. A baseline of 4 is appropriate for zero-parameter tools.

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 action ('Trigger') and resource ('active audio playlist'), with the specific effect 'restart from beginning' adding useful detail. It distinguishes from some siblings like 'audio_trigger_active_next' or 'audio_trigger_active_previous', but doesn't explicitly contrast with all audio-related tools.

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?

No guidance is provided on when to use this tool versus alternatives like 'audio_trigger_focused_playlist' or 'audio_trigger_playlist'. The description implies it operates on the 'active' playlist, but doesn't clarify prerequisites or when this tool is appropriate compared to other trigger operations.

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