getplaylistbyid

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It fails to indicate that this is a read-only operation, nor does it mention any required permissions, potential errors, or side effects. The description is too sparse to guide the agent on behavioral expectations.

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 that gets straight to the point. It is appropriately front-loaded and contains no unnecessary words. However, it is so minimal that it sacrifices informative content for brevity.

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 simplicity of the tool (one parameter, no output schema), the description provides the minimum viable information. However, it lacks details about the return value, error scenarios, or how the ID is used. For a tool with many siblings, more context would improve completeness.

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 covers both required and optional parameters, with a description for the 'id' parameter ('Playlist Id'). The tool description does not add any further meaning beyond what the schema already provides. Since schema coverage is 100%, a baseline score of 3 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 clearly states the action ('Gets') and the resource ('a playlist by ID'), making the purpose immediately understandable. It effectively distinguishes this tool from siblings like getplaylists (which lists all playlists) and other CRUD operations.

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 implies the tool is used when a playlist ID is known, but it does not provide any explicit guidance on when to use this tool versus alternatives, such as getplaylists for listing or other playlist operations. No exclusions or context are mentioned.

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