playlists_trigger_focused_next

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

With no annotations, the description carries the full burden. It only states what the tool does but not side effects, return values, or state requirements. Simple action tools benefit from at least noting if it is a mutation or safe read (implied mutation here).

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 sentence that conveys the exact purpose. No wasted words; it is front-loaded and efficient.

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?

The tool is simple with no parameters and no output schema, so the description is nearly sufficient. However, it does not mention potential error conditions or prerequisites (e.g., 'requires a focused playlist'), leaving some gaps for an agent.

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?

There are zero parameters, so the description does not need to add parameter meaning. According to the guidelines, 0 parameters gets a baseline of 4. The description adds no parameter info but it is unnecessary.

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'), the resource ('next item'), and the context ('in the focused playlist'), which distinguishes it from sibling tools like 'playlists_trigger_focused' or 'playlists_trigger_next'.

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. There are many similar sibling tools (e.g., 'playlists_trigger_focused_item', 'playlists_trigger_next'), but the description does not explain the conditions or prerequisites (e.g., whether a playlist must be focused).

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