get_playlist_detail

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

The description discloses the return format (JSON string) but does not mention whether the operation is read-only, potential side effects, error conditions, or authentication requirements. With no annotations, this leaves significant behavioral aspects unspecified.

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 extremely concise, with a clear purpose statement and well-organized Args and Returns sections. It contains no redundant information and is easy to parse.

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?

The tool is simple with one parameter, and the description covers its basic purpose and return value. However, it lacks usage guidelines, alternative tool references, or any caveats, making it only minimally complete for a selection/decision scenario.

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 description restates the schema's type information (numeric ID) without adding deeper semantic context, such as how to obtain the ID or any constraints. Given 0% schema description coverage, this is minimal compensation.

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 fetches playlist details and the song list, using a specific verb and resource. It inherently distinguishes from sibling tools that target songs or albums, though it does not explicitly contrast with them.

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 instead of alternatives, nor any mention of prerequisites or exclusions. It simply states what the tool does.

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