playlists_trigger_active_presentation

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

No annotations are provided, so the description carries full burden. It implies a mutation ('trigger'), but doesn't disclose behavioral traits like side effects (e.g., starts playback, changes state), permissions needed, error conditions, or what 'active presentation' means. This is inadequate for a mutation tool with zero annotation coverage.

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, efficient sentence with zero waste. It's appropriately sized and front-loaded, directly stating the tool's action without unnecessary elaboration, earning its place fully.

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 (a mutation tool with no annotations and no output schema), the description is incomplete. It doesn't explain what 'trigger' entails behaviorally, what happens on success/failure, or how it interacts with the system state. For a tool that likely changes presentation playback, more context is needed.

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 0 parameters with 100% schema description coverage, so no parameter documentation is needed. The description doesn't add param info, but that's fine here. Baseline is 4 for zero parameters, as there's nothing to compensate for.

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 the active presentation in the playlist' clearly states the action (trigger) and target (active presentation in playlist), but it's somewhat vague about what 'trigger' means in this context (e.g., start, advance, activate). It doesn't distinguish from siblings like 'playlists_trigger_active_announcement' or 'trigger_active_presentation', leaving ambiguity about playlist-specific vs. general triggering.

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 like 'playlists_trigger_focused', 'playlists_trigger_next', and 'trigger_active_presentation', the description lacks context on prerequisites (e.g., requires an active presentation) or comparisons, leaving the agent to guess based on naming alone.

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