getMyPlaylists

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

No annotations are provided, so the description carries full burden. It only restates the purpose and adds 'current user's', but doesn't disclose behavior like authentication requirements, pagination, default limit, or whether the returned playlist objects contain tracks. This is a gap for a read operation with no other context.

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 with no fluff. It delivers the essential information 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?

For a simple list tool with one optional parameter and no output schema, the description covers the core functionality and context. However, it lacks any mention of authentication or return format, but given the tool's simplicity and the presence of sibling auth tools, the description is mostly complete. It earns a 4, not a 5, due to minor gaps.

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 100% for the single 'limit' parameter, which has a description ('Maximum number of playlists to return (1-50)'). The description does not add anything beyond the schema, so the baseline of 3 applies.

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 ('Get') and the resource ('a list of the current user's playlists on Spotify'), which distinguishes it from siblings like searchSpotify or getPlaylistTracks. It's specific and 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?

The description implies usage (when you need the current user's playlists), but it doesn't explicitly state when to prefer this over alternatives like searchSpotify, nor does it mention exclusions (e.g., 'not for playlists of other users'). The context is clear, but no explicit guidance is offered.

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