Behavior3/5

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 successfully reveals the matching logic (genre-based) and deduplication behavior (excluding existing tracks), but fails to disclose safety characteristics (read-only vs. destructive), rate limits, or authentication requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence of 14 words with zero redundancy. It is perfectly front-loaded with the action verb ('Find') and packs specific behavioral details (genre search, exclusion) without waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the existence of an output schema, the description appropriately omits return value details. However, with 0% parameter schema coverage, the description is incomplete regarding the two input parameters—specifically lacking details on the Spotify playlist ID format and the function of the limit parameter.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, requiring the description to compensate. It implicitly references source_playlist_id via 'playlist's vibe' but completely omits documentation for the limit parameter. The description does not specify expected ID formats or parameter constraints beyond the schema's type definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool finds tracks matching a playlist's vibe using specific mechanisms (searching top genres, excluding existing tracks). However, it does not explicitly differentiate from siblings like spotify_playlist_vibe or spotify_discover_by_mood, though the mechanism implies the distinction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides implied usage context through the exclusion logic ('excluding existing tracks'), but lacks explicit guidance on when to use this versus alternatives like spotify_playlist_radio or spotify_discover_by_mood. No prerequisites or when-not-to-use warnings are provided.

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