spotify_playlist_vibe

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

The description implies a read-only operation ('analyze'), but does not explicitly state that no modifications are made. Since no annotations are provided, the description carries the burden, but it fails to confirm non-destructive behavior or disclose any side effects.

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, focused sentence with no unnecessary words. The core action is immediately clear.

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 low-complexity tool with one parameter and an output schema, the description covers the basic purpose. However, it omits details about the output structure (e.g., what 'genre makeup' means) and any limitations, leaving some ambiguity about the tool's full capabilities.

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?

The input schema has only one self-explanatory parameter (playlist_id) with 0% schema description coverage. The description does not add any extra meaning or format guidance, but the parameter is simple enough that an agent can infer its meaning from the schema title alone.

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?

Description clearly states it analyzes vibe, energy, and genre makeup using artist genre data, which distinguishes it from generic playlist analysis tools. However, it does not explicitly differentiate from the similar sibling spotify_playlist_analysis.

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 like spotify_playlist_analysis, nor any prerequisites or exclusions. The agent must infer usage solely from the verb 'analyze'.

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