spotify_delete_playlist

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the ownership requirement and clarifies that 'delete' means 'unfollow', but it does not state whether the action is irreversible, what permissions or scopes are needed, or what side effects occur for other users.

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 with no filler. The core operation is front-loaded, and the ownership constraint follows immediately as necessary context.

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 tool with full schema coverage and no output schema, the description gives enough to call it correctly: what it does and who can do it. Minor gaps remain around irreversibility and side effects, but these are not strictly required for a low-complexity mutation.

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 100%, so the single 'playlist_id' parameter is already fully documented. The description adds no additional syntax, format, or scoping detail beyond the schema, making the baseline score 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?

States a specific verb ('Delete') and resource ('playlist'), and clarifies that this is equivalent to unfollowing. The operation is clearly distinct from sibling playlist tools such as create, update, and remove-from-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?

Provides one important precondition ('You can only delete playlists you own'), which tells the agent when this tool will succeed. However, it does not name or compare against alternatives, so usage is only implied from the operation itself.

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