createPlaylist

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

No annotations are provided, so the description alone must disclose behavioral traits. It only says 'create' without explaining side effects (e.g., the playlist is added to the user's library), authentication needs, rate limits, or return value. This is minimal transparency for a mutation tool.

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, front-loaded sentence: 'Create a new playlist on Spotify'. It is concise and contains no filler or redundant details, earning a maximum score.

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?

The tool is simple and the parameter schema is fully described, but the description lacks usage guidelines and behavioral context, and there is no output schema to indicate return values. It is minimally adequate for selection but has clear gaps regarding side effects and invocation expectations.

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 provides full descriptions for all three parameters (name, public, description), achieving 100% schema description coverage. The description adds no additional parameter meaning, but the schema fully compensates, so a baseline of 3 is appropriate.

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 'Create a new playlist on Spotify' uses the specific verb 'Create' and names the resource 'playlist' and platform 'Spotify', clearly distinguishing it from sibling tools like searchSpotify or addTracksToPlaylist. It unambiguously identifies the tool's core action.

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. It does not mention prerequisites like authentication, nor does it contrast with related tools such as addTracksToPlaylist or getMyPlaylists. There is no when/when-not context.

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