playlists_trigger_focused

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'trigger' implies a mutation action but fails to specify effects (e.g., starts playback, changes state), permissions required, error conditions, or side effects. This leaves critical behavioral traits undocumented for a tool that likely modifies system state.

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, concise sentence, but it's under-specified rather than efficiently informative. While it avoids verbosity, it fails to provide essential context, making it less helpful than a more detailed yet still concise description would be.

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 implied by sibling tools (e.g., various trigger actions) and the lack of annotations and output schema, the description is incomplete. It doesn't explain what 'trigger' entails, what 'focused playlist item' means, or the expected outcome, leaving significant gaps for understanding and usage.

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 information is needed. The description doesn't add parameter details, which is appropriate, earning a baseline score of 4 for adequately handling the absence of parameters without unnecessary elaboration.

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 'Trigger the focused playlist item' restates the tool name 'playlists_trigger_focused' with minimal elaboration, making it tautological. While 'trigger' implies an action, it doesn't specify what 'trigger' means in this context (e.g., start playback, activate, execute) or what a 'focused playlist item' refers to, leaving the purpose vague.

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 its many siblings, such as 'playlists_trigger_focused_next', 'playlists_trigger_focused_previous', or 'playlists_trigger_active_presentation'. The description lacks context about prerequisites (e.g., needing a focused playlist first) or alternatives, offering no usage direction.

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