Create playlist

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

With no annotations, the description carries the full burden. It discloses that the playlist starts empty, that optional params can be added later via update_playlist, and that add_playlist_item is needed to fill it. It also hints at duplicate-name considerations. This is strong behavioral context, though it doesn't cover error handling or permissions.

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 well-structured with clear sections and front-loaded purpose. Every sentence provides valuable information, and the length is appropriate for the tool's complexity without unnecessary verbosity.

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 no output schema and no annotations, the description covers all essential aspects: what it does, when to use it, what parameters are needed, and post-creation steps. It is complete for an AI agent to select and invoke the tool correctly.

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 67%, with name lacking a description. The description compensates by clarifying that name is the only required parameter, and that default_interval and image_uri are optional and can be added later via update_playlist. This adds meaning beyond the schema's basic descriptions.

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 begins with 'Create a new empty playlist in the calling tenant,' which is a specific verb+resource statement. It clearly distinguishes the tool from siblings like list_playlists, get_playlist, update_playlist, and add_playlist_item.

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 includes explicit 'When to use' and 'When NOT to use' sections, providing clear guidance on bootstrapping content or splitting a playlist, and warns to list_playlists first to avoid duplicate names. This fully contextualizes when to use this tool over alternatives.

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