delete_playlist

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

With no annotations provided, the description carries the transparency burden. It discloses two key behavioral traits: the operation is mutative (requires the env flag) and non-destructive to media ('without deleting the underlying media'). It does not discuss irreversibility or error handling, but for a simple delete operation this is reasonable.

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 conveying all essential information without fluff. Every phrase adds value: the action, the side effect, and the configuration prerequisite.

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?

Given the tool's simplicity (one required parameter, no output schema), the description covers the core aspects: what it does, its side effect, and a major prerequisite. It could optionally mention the return behavior or confirm permanence, but these are implicit in a delete operation.

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 fully describes the only parameter (playlistId as 'Playlist rating key'), giving 100% schema coverage. The tool description adds no additional meaning about the parameter, so it does not exceed the schema baseline.

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 and resource: 'Delete a Plex playlist' clearly identifies the action. It also distinguishes this from related sibling tools like remove_from_playlist or clear_playlist by clarifying it deletes the playlist itself while preserving the underlying media.

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 clear context that this tool deletes the entire playlist (not individual items) and states a prerequisite (PLEX_ENABLE_MUTATIVE_OPS=true). However, it does not explicitly mention when not to use it or suggest alternatives for removing items from a playlist.

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