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. It comprehensively describes the return structure including success, playlist list with fields, total count, message, and error. However, it lacks disclosure of authentication needs or rate limits, which would improve transparency.

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 concise and well-organized with sections for 'Arguments' and 'Returns'. Every sentence provides value, with no redundancy or fluff.

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 that the tool has no parameters and a detailed output schema expressed in the description, the description is fully complete. It covers all necessary information 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?

There are no parameters, and the input schema is empty. The description explicitly states 'Arguments: None (no parameters required)', which adds clarity beyond the schema. Schema coverage is 100% (trivially).

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 tool's function: 'Get current user's playlists'. It specifies the resource (playlists) and the subject (current user), distinguishing it from sibling tools like 'create_playlist' or 'add_tracks_to_playlist'.

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 explicitly notes that there are no parameters required, making usage clear. It does not provide when-not-to-use advice or mention alternatives, but for a zero-parameter reading tool, this is sufficient context.

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