Get Spotify Albums

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false. The description adds value by revealing that albums are fetched through a singular endpoint and that unknown IDs are reported separately, which is behavioral context not present in the annotations.

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 concise sentences pack all necessary information. The first sentence states the primary purpose; the second adds a key behavioral detail. No filler or redundant content.

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?

For a single-parameter, read-only tool with an output schema and strong annotations, the description is complete. It covers the core operation and edge-case behavior (unknown IDs) without requiring additional explanation.

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%, but the description clarifies that 'exact Spotify album IDs' are expected and that unknown IDs are handled separately. This adds meaning to the album_ids parameter beyond its raw schema definition, though it doesn't specify ID format or additional constraints beyond what schema provides.

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 'Return' and resource 'typed details for exact Spotify album IDs', which distinguishes it from sibling tools like spotify_album_tracks (tracks of an album) or spotify_saved_albums (user's saved albums). It unambiguously tells the agent what this tool does.

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?

The phrase 'for exact Spotify album IDs' implies usage when you have specific album IDs and need details. It also mentions 'unknown IDs are reported separately', giving behavior context. However, it does not explicitly compare to alternatives or state when not to use it, so it stops short of a 5.

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