playlists_trigger_focused_item

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

No annotations are provided, so the description carries full burden. It states the action is to 'trigger,' implying a state change or activation, but doesn't disclose behavioral traits like side effects, permissions needed, error conditions, or what 'trigger' entails (e.g., starting playback, advancing a slide). This leaves significant gaps for safe and effective use.

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, making it highly concise and front-loaded. It efficiently communicates the core action 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?

Given the complexity of triggering actions in a media context and the lack of annotations and output schema, the description is incomplete. It doesn't explain what 'trigger' means operationally, potential outcomes, or error handling, leaving the agent with insufficient context for reliable use.

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 input schema has 100% description coverage, with 'index' clearly documented as 'The item index to trigger.' The description adds no additional parameter semantics beyond this, so it meets the baseline of 3 where the schema does the heavy lifting without extra value from the description.

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 target ('specific item in the focused playlist'), making the purpose understandable. However, it doesn't explicitly differentiate from similar sibling tools like 'playlists_trigger_item' or 'playlists_trigger_focused', which might cause confusion about scope.

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. With many similar 'trigger' tools in the sibling list (e.g., 'playlists_trigger_item', 'playlists_trigger_focused'), the description lacks context about prerequisites, such as needing a focused playlist, or comparisons to other triggering methods.

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