delete_playlist

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

Since no annotations are provided, the description carries the full behavioral burden. It explicitly reveals the destructive nature and the crucial irreversibility for owned playlists, which is the most important safety-relevant behavior. It omits permission requirements or effects on collaborators, but the core risk is clearly disclosed.

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?

One sentence contains the action, scope, and an important qualification. It is front-loaded, wastes no words, and conveys the essential information immediately.

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 destructive operation with one parameter and no output schema, the description covers what happens, the library context, and irreversible consequences. No extra return-value detail is needed, and the agent has enough to call the tool safely.

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 description coverage is 0%, so the description must compensate for the single parameter. It confirms that the parameter identifies a playlist from the user's library, but does not detail the expected format, source, or ownership implications of playlist_id beyond its schema name.

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') and identifies the exact resource ('a playlist from the user's library'). The parenthetical '(unfollow)' and the irreversibility statement help distinguish this from similar operations like remove_tracks or update_playlist.

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?

There is no guidance on when to choose this tool over alternatives such as remove_tracks, update_playlist, or create_playlist. It does not state preconditions like playlist ownership or when removal from the library is appropriate, leaving routing decisions to the agent.

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