get_playlist

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

No annotations exist, so the description must fully disclose behavior. It states 'Fetch' (read-only) and hints at a track limit, but does not mention authentication, rate limits, error handling, or what happens if the identifier is invalid. The behavior is minimally conveyed.

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?

A single, front-loaded sentence conveys the core purpose efficiently. No redundant words, though the backtick formatting around max_tracks is slightly informal.

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 presence of an output schema, the description does not need to detail return values. However, it lacks mention of pagination, track object details, or constraints (e.g., max tracks for non-owner playlists). For two parameters, it provides sufficient but not complete context.

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 coverage is 0%, so the description must compensate. It explains max_tracks as an upper limit and indicates value accepts URL, URI, or ID, but does not specify the expected format (e.g., full URL vs. Spotify ID). This adds some meaning but leaves ambiguity.

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 ('Fetch'), the resource ('a playlist'), and identifies multiple identifier types (URL, URI, or ID) and a parameter constraint (up to max_tracks tracks). This specificity distinguishes it from sibling tools like get_track or get_album.

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?

No guidance is provided on when to use this tool versus alternatives like search or get_playlists. The description implies usage for fetching a single playlist but lacks when-not-to-use or context about prerequisites.

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