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

Adds real value beyond the annotations by disclosing that the call may consume paid credits, that confirm=true is mandatory, and that the read-like POST does not publish to social platforms — important context given readOnlyHint=false. It stops short of noting rate limits or failure/error behavior.

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?

Two sentences, front-loaded with purpose followed by caveats. Efficient, though the long enumeration of return fields ('sharing details') is slightly padded.

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?

With no output schema, the description responsibly lists the returned fields and covers cost/confirmation caveats. The remaining gap is that it never routes the agent to alternatives such as spotify_search.

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 100%, so the schema already documents id, url, account, and confirm. The description only echoes the id/URL interchangeability and the confirm requirement, adding no syntax or format detail beyond the schema.

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?

Names a specific verb (retrieves) and resource (Spotify album) and enumerates the payload contents — metadata, artists, release date, cover art, copyright, tracks, sharing. It is clearly distinguishable from siblings like spotify_track or apple_music_album by the resource itself, though it never explicitly contrasts with them.

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?

Gives cost/auth context (paid credits, confirm=true) but no when-to-use guidance: nothing tells the agent when to prefer the id vs url parameter, or when to reach for spotify_search first. Usage is implied by the resource name rather than stated.

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