spotify_profile_playlists

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

No annotations are provided, so the description carries full burden. It discloses that it returns 'normalized public playlists' but does not mention any behavioral traits such as rate limits, authentication requirements, data freshness, pagination behavior (despite offset/limit parameters), or what 'normalized' means. It is missing important context for an agent to safely and effectively use the tool.

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 brief, with two sentences. The first sentence states the core purpose, and the second adds detail on input parameters and default behavior. There is no unnecessary information, but it could be slightly more structured (e.g., bulleting parameters).

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 no output schema and 5 optional parameters, the description provides the essential purpose and input guidance. However, it lacks details on expected output format, error conditions, and behavioral notes (e.g., pagination). It is minimally viable but not comprehensive.

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% description coverage, providing a baseline of 3. The description adds value by explaining the relationship between username, uri, and url, and the default behavior when none are provided. However, it does not elaborate on offset and limit beyond what is in the schema.

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 verb 'Retrieve' and the resource 'Spotify public profile playlists'. It specifies that it returns normalized public playlists from Spotify's Web Player user-profile service, and distinguishes from similar tools like spotify_profile or spotify_playlists_search by focusing on a user's public playlists.

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 mentions that users can provide username, uri, or url, and defaults to Spotify's official profile, which implies basic usage. However, it does not explicitly guide when to use this tool versus sibling tools like spotify_profile (user info) or spotify_playlists_search (search all playlists), nor does it state exclusions or prerequisites.

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