spotify_get_audio_features

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

No annotations are provided, and the description does not disclose behavioral traits such as authentication requirements (bearer token is a parameter but not explained), rate limits, error handling, or what happens if the track_id is invalid. For a 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 sentence of 12 words, very concise and front-loaded. However, it lacks necessary detail for a tool with no annotations or output schema, making it slightly under-specified for its context.

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 no annotations, no output schema, and 0% schema description coverage, the description is insufficient. It does not cover authentication, return format, or potential errors, leaving significant gaps for an agent to use it correctly.

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 coverage is 0% with two required parameters. The description does not explain the purpose of 'bearer_token' (e.g., how to obtain it) or 'track_id' (e.g., format, source). It only says 'for a Spotify track', which adds little beyond the parameter names.

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 verb 'Get', the resource 'audio analysis features', and specifies it's for a 'Spotify track'. It lists example features (danceability, energy, tempo) which distinguish it from sibling tools like spotify_get_track or spotify_get_album.

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 siblings like spotify_get_track or spotify_get_album. The context signals list many sibling tools, but the description offers no differentiation or usage scenario.

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