playlists_trigger_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 mentions 'trigger' but doesn't clarify what triggering entails—whether it starts playback, activates a cue, or performs another action. It omits details like side effects, permissions needed, or response behavior, leaving significant gaps in understanding the tool's operation.

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. It's front-loaded and efficiently conveys the core action, making it easy to parse quickly 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 no annotations and no output schema, the description is incomplete for a tool that performs an action ('trigger'). It lacks details on what triggering does, expected outcomes, error conditions, or how it interacts with system state, making it insufficient for reliable agent use in a complex environment with many sibling tools.

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?

Schema description coverage is 100%, with clear parameter descriptions in the schema. The description adds no additional meaning beyond implying that 'index' refers to an item position, which is already covered. Baseline 3 is appropriate as the schema handles parameter documentation adequately.

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 resource ('specific item in a playlist'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'playlists_trigger_focused_item' or 'audio_trigger_playlist_item', which likely serve similar triggering functions in different contexts.

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 sibling tools involving triggering (e.g., 'playlists_trigger_focused_item', 'audio_trigger_playlist_item'), the description lacks context about prerequisites, target state, or distinctions from other triggering methods.

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