playlists_trigger_focused_next

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

No annotations are provided, so the description carries full burden. While 'trigger' implies an action that changes state, the description doesn't disclose what 'next item' means (e.g., sequential order, playlist logic), whether this requires specific permissions, what happens if no playlist is focused, or what the expected outcome is. This leaves significant behavioral uncertainty.

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, clear sentence with zero wasted words. It's front-loaded with the core action and target, making it immediately understandable without any 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 zero-parameter tool with no output schema, the description provides the basic purpose but lacks important context. Without annotations, it doesn't clarify behavioral aspects like what 'focused playlist' means, what 'trigger' actually does, or potential error conditions. Given the complexity implied by sibling tools, more completeness would be helpful.

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, and schema description coverage is 100%, so there's no need for parameter documentation in the description. The description correctly doesn't mention any parameters, which is appropriate. A perfect score is reserved for when parameters exist and the description adds meaningful context beyond the schema.

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 ('next item in the focused playlist'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from similar sibling tools like 'playlists_trigger_focused' or 'playlists_trigger_focused_previous', 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 many similar sibling tools (e.g., 'playlists_trigger_focused', 'playlists_trigger_focused_previous', 'audio_trigger_focused_next'), there's no indication of what makes this specific tool appropriate or when other tools should be used instead.

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