getAlbums

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

With no annotations, the description carries the full disclosure burden, and it delivers little: no mention of auth requirements, whether the call is read-only, what happens with invalid or missing IDs, or how results are ordered/paginated. 'One or more' hints at batch semantics but that is already implied by the schema.

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?

A single tight sentence with the resource and lookup key front-loaded and zero filler. It is efficient, though so short that conciseness comes at the cost of substance.

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 simple two-parameter read tool with no output schema and no annotations, the description is barely adequate. It never explains what 'detailed information' comprises or the dual-alias parameter, leaving the agent to rely entirely on the schema.

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 baseline is 3. The description adds only that lookups are 'by Spotify ID' and batched ('one or more'), which the schema already conveys through the string-or-array anyOf and maxItems: 20. It does not clarify the ids/albumIds alias duplication.

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 ('Get') plus resource ('detailed information about one or more albums') and the identifier basis ('Spotify IDs'), so an agent can separate it from getAlbumTracks or searchSpotify. It does not name a sibling explicitly, so it falls short of a 5.

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?

There is no guidance on when to use this versus alternatives such as getAlbumTracks (tracks within an album) or searchSpotify (discovery). The only implied condition is 'you already have album IDs', which is left for the agent to infer.

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