Get a playlist's tracks

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

The readOnlyHint annotation already indicates a safe read operation; the description adds the detail that the full track list is returned and that lookup can be by id or name. It does not disclose the existence of the limit parameter, which may implicitly restrict the 'full' list, nor does it describe return structure or pagination, so behavioral transparency is moderate.

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, well-structured sentence that immediately states the resource and selection method. It is free of fluff and front-loads the core action, achieving maximum conciseness.

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 read-only tool with no output schema, the description covers the primary use case and the id/name selection mechanism. However, the limit parameter is not mentioned, and there is no guidance on how the result set behaves (e.g., default limit, pagination), leaving a notable gap given the schema provides no parameter descriptions.

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 clarifies that name and playlist_id are alternative selectors, but it ignores the limit parameter entirely. Given three undocumented parameters and the need to explain all, this partial coverage is insufficient.

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 the full track list of a single playlist, with explicit selection by id or name. It distinguishes itself from siblings like list_playlists (which lists playlists) and search_tracks (which searches tracks globally), making the purpose 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?

Usage context is implied: use this tool when you need a playlist's tracks and know the playlist's id or name. However, there is no explicit comparison to alternatives such as describe_library or list_playlists, nor any 'when not to use' guidance, leaving room for confusion in selecting among similar tools.

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