create_playlist

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

With no annotations provided, the description must carry the behavioral disclosure burden. It does state that the playlist is owned by the current user and that the created playlist is returned, which is useful. But it does not disclose authorization requirements, side effects beyond creation, or any limitations such as playlist name uniqueness.

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, well-structured sentence that leads with the action and includes the key ownership and return behavior. There is no filler or redundant wording.

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?

The input schema and presence of an output schema help, but the description alone leaves gaps around parameter meaning and when to select this tool over siblings. It is minimally adequate for a straightforward create call but not fully complete.

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 needed to explain the parameters (name, public, description), but it does not. The only mention of 'name' refers to the return value, not the input parameter. The schema provides types and defaults but no semantic explanation.

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 the specific verb 'Create' with a clear resource, 'a new playlist owned by the current user', and even notes the return value. This distinguishes it from sibling tools like get_playlists or add_tracks_to_playlist without ambiguity.

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 purpose strongly implies when to use it: when a new playlist should be created for the current user. However, it does not explicitly mention alternatives or conditions like 'do not use this for adding tracks' or 'use get_playlists to list existing playlists'.

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