spotify_find_vibe_matches

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

Describes core behavior: searches by top genres and excludes existing tracks. No annotations provided, so description carries burden. It is clear and appropriate for a read-only search tool, though no mention of authentication or rate limits.

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?

Extremely concise: two sentences, no wasted words. The main action and key detail (exclusion) are front-loaded.

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 has an output schema (return values presumably documented), two clearly named parameters, and no annotations, the description is nearly complete. It explains the logic and distinguishes from siblings. Minor gap: no mention of limit default or output format.

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 schema coverage at 0%, description only loosely mentions the source playlist (implied by 'source_playlist_id') but fails to describe the 'limit' parameter or its default. Parameter names are self-explanatory but not reinforced.

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?

Clearly states the verb 'Find' and resource 'tracks that match a playlist's vibe'. Specifies the method (searching top genres) and exclusion of existing tracks, distinguishing it from siblings like 'spotify_vibe_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?

Implies usage context (given a playlist, find similar tracks) but does not explicitly state when to use versus alternatives like 'spotify_discover_by_mood' or 'spotify_vibe_playlist'. No guidance on when not to use.

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