audio_trigger_active_next

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

No annotations are provided, so the description carries full burden. 'Trigger' implies a state-changing action, but the description doesn't disclose what happens (e.g., does it play audio immediately, queue it, or advance playback?), potential side effects, permissions needed, or error conditions. 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 a single, direct sentence with no wasted words. It's front-loaded with the core action and target, making it immediately clear without 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 state-changing tool with no annotations and no output schema, the description is insufficient. It lacks details on what 'trigger' entails behaviorally, what the expected outcome is, or any error handling. Given the complexity implied by 'active playlist' and the absence of structured data, more context is needed.

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 0 parameters with 100% schema description coverage, so no parameter documentation is needed. The description appropriately doesn't mention parameters, which is efficient. A baseline of 4 is given since it doesn't need to compensate for any parameter gaps.

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 the target ('next item in the active playlist'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from similar sibling tools like 'audio_trigger_active_previous' or 'audio_trigger_focused_next', which would be needed for 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 multiple similar triggering tools in the sibling list (e.g., 'audio_trigger_active_previous', 'audio_trigger_focused_next'), there's no indication of context, prerequisites, or distinctions between them.

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