Delete a playlist

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

Annotations only provide destructiveHint: true. The description adds meaningful context: 'Permanently delete' reinforces irreversibility, and 'Does not touch the audio files' clarifies a key behavioral boundary. This goes beyond what the annotation alone conveys.

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 two short sentences that immediately state the action and a crucial caveat. There is no filler or redundancy; every word earns its 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 delete operation, the description covers purpose and safety, and the destructiveHint annotation adds context. However, it omits guidance on parameter selection and the fact that both parameters are optional, which is a notable gap given the schema provides no descriptions and there is no output schema.

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 coverage is 0% and the description makes no mention of the parameters 'name' and 'playlist_id.' The agent receives no guidance on which to use, whether they are alternatives, or which is required (especially since both are optional in the schema). The description fails to compensate for the schema's lack of parameter documentation.

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: 'Permanently delete a playlist.' It clearly distinguishes from sibling tools like update_playlist and get_playlist, and adds the clarifying statement 'Does not touch the audio files' to define the scope.

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?

No guidance is given on when to use this tool versus alternatives. It does not mention prerequisites (e.g., needing a playlist_id from list_playlists) or explicitly say 'use when you want to remove a playlist.' The context of siblings is not leveraged to explain when not to use it.

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