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

Adds real context beyond the readOnlyHint/openWorldHint annotations by disclosing that no Spotify bearer token is required, which is an auth-behavior detail an agent needs. It also implies paginated track retrieval via limit/offset, though it doesn't state return format details.

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 compact clauses with zero filler, front-loading the purpose before the usage guidance. Efficient and well-structured for an agent scanning options.

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 an output schema present, return values needn't be explained, and the description covers the key input (album URI/ID), the auth caveat, and the search fallback. Complete enough for correct invocation; only the lack of distinction from spotify_album_tracks leaves a minor gap.

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 100%, so the schema already documents id, uri, limit (1-50 clamp), and offset. The description only restates that it works with an album URI or ID and adds no syntax or format clarity beyond the schema. Baseline 3 is appropriate.

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?

States a specific verb and resource: returns Spotify album metadata plus track listings, keyed by album URI or ID. This clearly distinguishes it from search-type siblings. However it doesn't distinguish itself from the sibling spotify_album_tracks, which presumably also returns track listings, so sibling separation is incomplete.

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?

Explicitly says 'Use when you have an album URI or ID; search first only if you need to find one,' naming the prerequisite alternative (search) and the condition that selects it. No exclusion against spotify_album_tracks is given, but the core when-to-use guidance is clear.

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