SpotifyPlaylist

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

With no annotations, the description carries full burden but provides minimal behavioral insight. 'Manage' implies both read and write operations, but it doesn't disclose permissions needed, rate limits, side effects (e.g., playlist deletion), or response formats. This is inadequate for a multi-action tool with potential destructive operations like 'delete'.

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 extremely concise ('Manage Spotify playlists.') with no wasted words. It's front-loaded and to the point, though this brevity contributes to gaps in other dimensions. Every sentence (here, just one) earns its place by stating the core function.

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 tool's complexity (6 parameters, multiple actions including destructive ones like 'delete'), no annotations, and no output schema, the description is insufficient. It doesn't explain return values, error handling, or behavioral nuances, leaving critical gaps for an AI agent to operate safely and effectively.

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 parameters are well-documented in the schema. The description adds no additional meaning beyond the schema's details. Baseline 3 is appropriate as the schema handles parameter semantics effectively, though the description doesn't compensate or enhance understanding.

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 'Manage Spotify playlists' states the general purpose (verb+resource) but is vague about what 'manage' entails. It doesn't differentiate from sibling tools like SpotifyLikedSongs or SpotifyQueue, which also handle playlist-related content. The description is functional but lacks specificity about the scope of operations.

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. The description doesn't mention prerequisites (e.g., authentication), exclusions, or comparisons to siblings like SpotifyGetInfo or SpotifyPlayback. Usage is implied through the action parameter but not explicitly stated in the description.

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