playlists_focus_next

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not explain what 'focus' entails (e.g., state change, visual indication), whether it triggers any side effects, or if it requires a specific playlist state. The description is too terse to inform an agent about behavioral impacts.

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, front-loaded sentence with zero wasted words. It is maximally concise for the information it conveys.

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 simplicity of the tool (no parameters, no output schema, no annotations), the description should provide enough context for an agent to use it correctly. It fails to clarify what 'next' means in relation to the playlist order, whether it requires a playlist to be currently focused, or what the expected outcome is. More completeness is needed for a zero-param no-annotation tool.

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 the schema is trivially covered (100%). The description adds no meaning beyond the tool name, as 'Focus the next playlist' is essentially a restatement. With no parameters, the baseline is 4, but the lack of additional context reduces the score to 3.

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 'Focus the next playlist' clearly states the action (focus) and resource (playlist) with a directional qualifier ('next'), making the core purpose self-evident. However, it does not differentiate from sibling tools like playlists_focus_previous or audio_focus_next_playlist, slightly lowering the 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, such as playlists_focus, playlists_focus_previous, or audio_focus_next_playlist. There is no mention of prerequisites, context, or when not to use it.

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