spotify_get_track

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

With no annotations, the description must convey behavioral traits. It only says 'Get metadata,' implying a read operation, but fails to mention authentication requirements (bearer token is in schema but not explained), rate limits, or the nature of the return data. This is minimal transparency.

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 that front-loads the verb and resource. It is efficient with no unnecessary words. However, it could be slightly more informative without sacrificing conciseness.

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 presence of many sibling Spotify tools (e.g., spotify_get_album, spotify_get_audio_features) and no output schema, the description is insufficient. It does not clarify what 'metadata' includes or when to prefer this tool over similar ones, leaving the agent underinformed.

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 0%, and the description does not explain any parameters. It only implies that track_id is used (by saying 'by ID'), but provides no details on bearer_token, market, or what valid values are. The description adds no semantic value 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 states 'Get metadata for a Spotify track by ID,' which clearly identifies the verb (Get), resource (metadata for a Spotify track), and method (by ID). This differentiates from siblings like spotify_get_album or spotify_get_artist, though it could be more explicit about what 'metadata' includes.

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 such as spotify_get_audio_features or spotify_search. The description does not mention use cases, prerequisites, or exclusions.

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