get_playlists_by_id

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the specific HTTP method and path, which clarifies the operation but provides no additional behavioral context such as response format, pagination, or error behavior.

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 front-loaded, with no fluff. The endpoint and argument are clearly presented in just a few linescar; however, the phrasing 'Get api playlists' is grammatically awkward and the essential information is almost too sparse to be called well-structured.

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?

With one required parameter)Skip? needs completion: For a simple read-only operation with an output schema and comprehensive annotations, the description covers the core invocation. Yet it does not explicitly mention that this gets a single playlist by its identifier, nor does it distinguish itself from list_playlists, leaving some contextual gaps.

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 must compensate. It only states 'id: Path parameter,' which adds the location of the parameter but not its semantics (e.g., that it is the playlist identifier, format, or examples). This leaves room for ambiguity about what value to provide.

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 states a clear verb ('Get') and resource ('api playlists'), and the HTTP path `GET /api/playlists/{id}` indicates this fetches a specific playlist by ID. It does not explicitly differentiate from `list_playlists`, but the path parameter and singular resource make the operation largely unambiguous.

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?

No guidance is given on when to use this tool versus alternatives like `list_playlists` or `get_libraries_by_id`. The description only states the endpoint without any context, prerequisites, or exclusion conditions.

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