spotify_check_playlist_followers

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It only discloses the maximum number of user IDs but does not mention whether the operation is read-only, what happens if more than 5 IDs are provided, or the format of the response.

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, clear sentence with no redundant information. It conveys the essential purpose and constraint efficiently.

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 that an output schema exists, the description does not need to detail return values. It covers the core functionality and a key limitation. Some edge cases (e.g., error handling, ID format) are omitted, but overall it is sufficient for a simple check tool.

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 clarify parameters. The description adds the 'max 5' constraint for user_ids, which is not in the schema. However, it does not explain the playlist_id format or the expected format of user IDs (e.g., Spotify IDs or usernames).

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 ('Check if specific users follow a playlist') and resource (playlist). It also includes a constraint ('max 5 user IDs'), which distinguishes it from sibling tools like spotify_check_following_artists or spotify_check_saved_tracks.

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 implicitly suggests when to use this tool (to check playlist followers) and includes a practical limit (max 5 IDs). However, it does not explicitly mention when not to use it or suggest alternative tools.

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