unfollowPlaylist

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

No annotations are provided, so the description carries the burden. It discloses a key limitation (no permanent deletion via the API) and clarifies the action as removal from the user's library. However, it doesn't mention auth requirements, idempotency, or the effect on playlists the user owns, leaving room for more transparency.

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?

Two short sentences: the first states the action, the second adds a crucial API limitation. No unnecessary words; both sentences earn their place.

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?

For a simple one-parameter mutation with no output schema, the description covers the essential scope and a key limitation. It doesn't specify success/error responses or auth, but these are not critical given the tool's simplicity. Slightly more detail could make it fully complete.

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 has 100% coverage for the single parameter playlistId, with a clear description. The tool description adds no extra parametric detail, but the schema already provides adequate meaning. Baseline 3 applies.

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 uses a specific verb 'Remove' with a clear resource ('playlist from the current user's library') and clarifies the action as 'unfollow'. It also distinguishes itself from permanent deletion via the note about Spotify API limitations, setting it apart from sibling tools like removeTracksFromPlaylist or updatePlaylist.

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 implies when to use the tool (to unfollow a playlist) but provides no explicit when-not-to-use guidance or alternatives. It doesn't reference sibling tools like getMyPlaylists or removeTracksFromPlaylist, so usage context is only implied.

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