get_user_playlists

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It states it returns public playlists but doesn't disclose pagination behavior, whether it requires an access token, or what happens if the user's playlists are private. For a read operation, this is a minimal disclosure.

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 wasted words. It front-loads the core purpose and is appropriately minimal for such a simple tool.

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 0% schema coverage and no annotations, the description is incomplete. It doesn't mention the required user_id parameter, access token handling, pagination defaults (limit, offset), or how to interpret the response. An agent calling this tool would need to guess at many details.

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 adds no information about any parameters. It doesn't mention user_id, limit, offset, or access_token semantics beyond what the schema's names suggest. The description fails to compensate for the lack of schema 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 clearly states the verb 'Get' and resource 'user's public playlists'. It is differentiated from the sibling 'get_current_user_playlists' by the 'public' qualifier, though it doesn't explicitly name the sibling. Still, the purpose is clear and specific.

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 'get_current_user_playlists' or when public playlists are needed. It doesn't mention authentication requirements or context of use. The agent is left to infer that it's for other users' playlists, not the current user's.

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