list_playlists

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

Annotations already declare the operation as read-only, idempotent, and non-destructive, and the GET method is consistent with that. The description adds no behavioral context beyond the annotations—such as pagination behavior, authentication needs, or response scope—so it provides little extra 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 very short and free of unnecessary filler, but 'Get api playlists' essentially restates the tool name and is redundant with the endpoint line. The brevity is more under-specification than purposeful conciseness, and no helpful differentiating context is included.

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?

For a zero-parameter, read-only list endpoint with an output schema, only a modest description is needed. The endpoint and resource are present, but the description does not clarify whether this returns the global playlist collection or a library-scoped one, which is a meaningful gap given the sibling tools.

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 input schema has zero parameters, so there is no parameter documentation burden for the description to carry. With 100% schema coverage and no parameters, the baseline of 4 is appropriate.

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 verb 'Get' with the resource 'playlists' and includes the exact endpoint 'GET /api/playlists', so the core operation is clear. However, it does not explicitly clarify whether this returns all playlists, a specific playlist, or library-scoped playlists, so it does not fully distinguish itself from sibling tools like get_playlists_by_id or get_libraries_by_id_playlists.

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. It does not mention that this lists all playlists or that get_playlists_by_id should be used for a single playlist, leaving the agent to infer usage from the tool name and endpoint.

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