C2.8/5.0
Behavior2/5

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

No annotations are provided, so the description must disclose behavioral traits. 'Trigger' implies a one-way action, but there is no information on destructiveness, idempotency, or side effects (e.g., does it start playing? change state?). The description fails to add any behavioral context beyond what the name suggests.

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

Conciseness3/5

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

The description is extremely concise (4 words), but it omits necessary details. Conciseness is positive only if clarity is maintained; here, it sacrifices clarity. A few more words to explain 'trigger' would improve it.

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

Completeness2/5

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

Given no annotations, no output schema, and a simple tool, the description should provide more context about preconditions, effects, or related operations. It is incomplete; for example, it does not mention that the focused item must exist in a playlist, or whether it triggers playback. This leaves ambiguity for the agent.

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

Parameters3/5

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

With zero parameters and 100% schema coverage, the description does not add meaning beyond the schema. It could have clarified what 'focused' means or how the tool selects the item, but it does not. A baseline of 3 is appropriate since no additional context is provided.

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

Purpose4/5

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

The description uses a specific verb 'Trigger' and resource 'focused playlist item', clearly indicating activation of the currently focused playlist item. It distinguishes from sibling tools like 'playlists_trigger_focused_next' and 'playlists_trigger_active_presentation' by specifying 'focused', but 'trigger' remains vague (e.g., what does triggering mean?). This is clear enough among many similar siblings.

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

Usage Guidelines2/5

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 such as 'playlists_trigger' or 'playlists_trigger_focused_item' (which appears as a sibling). The agent has no context on conditions like requiring a focused item to exist, or scenarios where other trigger tools are more appropriate.

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