unfollow_playlist

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

With no annotations, the description discloses that unfollowing removes the playlist from the user's library and profile, and for owned playlists it is equivalent to deletion. This is transparent about the primary behavior, though additional details about reversibility or permissions are omitted.

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 concise: two sentences directly stating the purpose and a key behavioral note. No unnecessary words or redundancy.

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 description explains input (playlist ID implied) and the effect (removal from library/profile). Since an output schema exists, the lack of return value details is acceptable. The explanation is sufficient for a simple mutation tool.

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 schema has 0% description coverage for the required parameter playlist_id. The description does not explicitly describe the parameter, but the verb 'unfollow a playlist' implies the ID is needed. Given only one parameter, the clarity is adequate but could be improved by explicitly stating the parameter role.

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 action: 'Unfollow (remove) a Spotify playlist from your library.' It further explains that for owned playlists, this acts as the only way to delete them, differentiating it from operations like removing tracks.

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 context on when to use the tool (to remove a playlist, especially to delete owned ones). It implicitly differentiates from sibling tools like remove_tracks_from_playlist, but does not explicitly list alternative tools or when not to use.

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