List KBK Playlists

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

With no annotations, the description carries the full burden. It does convey that the tool returns playlist names, types, genres, and track counts, which is useful behavioral context. However, it does not explicitly state read-only behavior, ordering, or any side effects, leaving some transparency gaps.

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 is front-loaded with the main subject ('All KBK playlists') and immediately lists return fields. Every word contributes value, with no fluff or repetition.

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 0-parameter, no-output-schema tool, the description covers the key data returned and the scope. It would benefit from explicitly stating the return format (e.g., an array of objects) or any limitations, but for its simplicity, it is nearly complete.

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 tool has zero parameters and 100% schema description coverage, so the schema already fully defines the input. The description adds no parameter info, but with no parameters, the baseline is 4, and no additional semantics are needed.

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 'All KBK playlists' with specific fields (name, type, genre, track count), making the tool's purpose unmistakable. It distinguishes from sibling 'get_playlist' by explicitly indicating a plural list of all playlists rather than a single one.

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 when to use this tool: whenever you need to list all playlists. It provides clear context ('All KBK playlists') but does not explicitly mention alternatives like 'get_playlist' for retrieving a single playlist, so it lacks exclusions/alternatives.

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