A4/5.0
Behavior3/5

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states 'trigger' but omits details like whether it requires a running playlist, what happens if no active presentation exists, or if it causes side effects (e.g., stopping other media).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no extraneous words. It directly conveys the tool's function without elaboration, making it maximally concise for a zero-parameter tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters, output schema, or annotations, the description is minimal but adequate for the simplest case. However, it lacks context about failure modes, prerequisites, or whether this tool can be used standalone or must follow other steps, leaving room for ambiguity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are no parameters, and the input schema covers 100% of the (empty) property list. The description adds meaning by confirming that the tool triggers the active presentation, which is the only semantic needed beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('trigger') and the target ('active presentation in the playlist'), making the purpose unmistakable. It distinguishes from siblings like playlists_trigger_active_announcement (different content type) and trigger_active_presentation (no playlist context).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no explicit guidance on when to use this tool versus alternatives. While the name and context imply it's for playlist-specific activation, there is no mention of preconditions (e.g., must have an active playlist) or exclusion of other triggers.

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