Get KBK Playlist

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

With no annotations provided, the description carries the full burden. It reveals the read-only nature via 'get' and describes the output structure (tracks with fields), but it does not explicitly state that it is a safe, non-mutating operation or mention any error/edge-case behavior. This is adequate but not rich.

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, front-loaded sentence: 'One playlist by id, including its tracks (title, artist, stream URL).' It conveys the essential function without any wasted words or unnecessary details.

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 simple one-parameter tool, the description adequately covers the key return value (the playlist and its tracks). It does not explain error handling or pagination, but given the straightforward nature of a get-by-id operation, it is sufficiently 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 input schema has 100% coverage with the parameter description 'The playlist id (from list_playlists)', which already provides the meaning. The tool description adds no extra context about the parameter, so it meets the baseline but does not exceed it.

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 retrieves a single playlist by ID and specifies what it includes (tracks with title, artist, stream URL). This distinguishes it from sibling tools like list_playlists and get_track by focusing on a specific playlist resource.

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 context is clear: use this when you have a specific playlist ID and want that playlist with its tracks. However, it does not explicitly mention when not to use it or name alternative tools like list_playlists for listing all playlists, so it falls just short of explicit guidance.

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