spotify_interleave_playlists

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

No annotations are present, so the description must carry the burden of behavioral disclosure. It states that the tool creates a new playlist (a mutation) and requires 2-5 source playlists. However, it does not explain error handling, side effects on source playlists, or whether the operation is idempotent.

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 sentence that packs all critical information: action, resource, method, and constraint. No extraneous text.

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 low complexity (2 params, straightforward action), the description covers the core behavior and range constraint. It misses describing the return value or output schema, but the presence of an output schema is noted in context signals. Sibling differentiation is implicit but not explicit.

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?

With 0% schema description coverage, the description partially compensates by mentioning 'source playlists' and the range. However, it does not explicitly link 'playlist_ids' to source playlists or describe the 'name' parameter beyond being the new playlist's name. The constraint of 2-5 is not enforced 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 'create', the resource 'new playlist', and the method 'round-robin interleaving' with a specific range of source playlists (2-5). This distinguishes it from siblings like merge_playlists or absorb_playlist.

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 spotify_merge_playlists or spotify_absorb_playlist. The agent is given no contextual hints about preferred use cases.

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