spotify_vibe_playlist

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

No annotations provided, so the description must disclose behavioral traits. It states 'Create a playlist' implying mutation, but lacks details on authentication requirements, whether it modifies existing playlists, or any side effects.

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 concise sentence that states the purpose without unnecessary words. It is front-loaded with the key action and resource.

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 tool has an output schema to explain return values, the description is partially complete. However, it lacks context about how the playlist is created (e.g., user's library or temporary) and how parameters like limit affect the output.

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 coverage is 0% for parameter descriptions. The description lists example mood values but does not explain the 'name' parameter (default null) or 'limit' (default 30). The mood parameter is partially clarified but not formally.

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 tool creates a playlist based on mood, listing specific mood examples. This distinguishes it from siblings like spotify_create_playlist (general creation) and spotify_discover_by_mood (discovery).

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 explicit guidance on when to use or not use this tool. The mood matching implies a clear use case, but there is no comparison to alternatives like spotify_discover_by_mood or spotify_playlist_vibe.

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