playlists_trigger

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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Trigger a specific playlist' gives minimal insight - it suggests an action but doesn't explain what 'trigger' entails (e.g., starting playback, activating, executing), whether it's a read or write operation, what permissions are needed, or what side effects occur. For a tool with no annotation coverage, this is inadequate behavioral transparency.

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 maximally concise with just three words. While it's under-specified in terms of content, it's not verbose or repetitive. Every word earns its place, and there's no wasted text. The structure is straightforward, though the brevity contributes to the lack of helpful information.

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 of the tool ecosystem (numerous sibling tools), lack of annotations, and absence of an output schema, the description is insufficiently complete. 'Trigger a specific playlist' doesn't explain what triggering means, how it differs from other triggering tools, what happens when invoked, or what the agent should expect. For a tool in this rich context with no structured behavioral hints, the description should provide more operational context.

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 input schema has 100% description coverage, with the single parameter 'playlistId' clearly documented as 'The ID of the playlist to trigger'. The description doesn't add any meaningful parameter information beyond what the schema provides. According to scoring rules, when schema_description_coverage is high (>80%), the baseline is 3 even with no param info in the description.

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 a specific playlist' is a tautology that essentially restates the tool name 'playlists_trigger'. While it identifies the resource (playlist) and implies an action (trigger), it lacks specificity about what 'trigger' means in this context. It doesn't distinguish this tool from numerous sibling tools like 'playlists_trigger_active_announcement' or 'audio_trigger_playlist', 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?

The description provides no guidance on when to use this tool versus alternatives. With many sibling tools involving playlist triggering (e.g., 'playlists_trigger_active_announcement', 'audio_trigger_playlist', 'playlists_trigger_focused'), there's no indication of how this tool differs or when it's appropriate. The description is completely silent on usage context, prerequisites, or exclusions.

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