spotify_create_playlist

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this creates a playlist but doesn't mention any behavioral traits: no information on permissions required, rate limits, whether the operation is idempotent, what happens on duplicate names, or what the response contains (e.g., playlist ID). For a mutation tool with zero annotation coverage, this is a significant gap.

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, efficient sentence that directly states the tool's purpose without any fluff or redundant information. It is appropriately sized and front-loaded, making it easy for an agent to parse quickly. Every word earns its place.

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 this is a mutation tool with no annotations and no output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., a playlist object or ID), error conditions, or behavioral constraints. While the schema covers inputs well, the overall context for safe and effective use is lacking, especially compared to siblings that might handle related operations.

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 100%, so the schema already documents all three parameters (name, description, public) with clear descriptions. The description adds no additional meaning about parameters beyond implying they relate to playlist creation. This meets the baseline of 3 when the schema does the heavy lifting, but no extra value is provided.

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 ('Create') and resource ('new playlist for the authenticated user'), making the purpose immediately understandable. It distinguishes from siblings like spotify_add_tracks_to_playlist (modification) and spotify_get_user_playlists (retrieval). However, it doesn't specify what type of playlist (e.g., music, podcast) or platform context, which prevents a perfect score.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., authentication via spotify_authenticate), when not to use it (e.g., for modifying existing playlists), or how it relates to siblings like spotify_get_user_playlists for listing playlists first. This leaves the agent to infer usage from context alone.

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