itunes_create_playlist

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

No annotations are present, and the description omits any mention of side effects, permissions, or potential behaviors (e.g., what happens if a playlist with the same name exists, whether it creates an empty playlist, or if it modifies the library). The user is left without information about the tool's internal behavior.

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, concise sentence with no redundant information. Every word contributes to conveying the tool's primary function.

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?

While the description is clear about the action, it lacks context about the result (e.g., what is returned or if anything is returned at all) and any side effects. Given no output schema, this is partially acceptable, but the description does not mention error handling or success criteria, leaving some gaps for a simple creation 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 description says 'with the given name,' which clarifies the 'name' parameter as the playlist's name, but provides no further detail such as allowed characters, length limits, or uniqueness requirements. It adds minimal meaning beyond the parameter's type.

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 clearly states the action (create) and the resource (a new playlist in Music), making it unambiguous. It effectively distinguishes from sibling tools like 'delete_playlist' or 'add_to_playlist' by explicitly naming the creation operation.

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 no guidance on when to use this tool versus alternatives, such as when to use 'add_to_playlist' or 'create_playlist_folder'. It gives no context about prerequisites or scenarios where this tool is preferred.

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