get_saved_albums

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

The annotations already declare readOnlyHint=true, and the description adds a useful behavioral trait: results are ordered most recently added first. It does not disclose pagination behavior beyond the schema's limit/offset defaults, but given the safety profile is already annotated, this is acceptable but not rich.

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, concise sentence with no filler. It front-loads the resource and then adds ordering context, but it could be slightly more structured by including an explicit verb like 'Retrieves'.

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, read-only paginated list with an output schema, the description is mostly sufficient: it names the resource and the sort order. It lacks explicit usage guidance and pagination semantics, but the output schema and annotations cover the main operational safety and return expectations.

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%, so the description must compensate for undocumented parameters, but it does not mention how limit or offset behave. The parameter names and defaults are somewhat self-explanatory, yet without any description of pagination semantics or bounds, the agent gets no added meaning.

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 identifies the resource ('albums saved to the user's library') and adds an ordering detail ('most recently added first'), which separates it from siblings like get_saved_tracks. However, it is a noun phrase rather than an explicit verb+resource statement, so it stops short of a fully explicit purpose declaration.

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 tool versus alternatives such as get_saved_tracks or get_artist_albums. The description implies a read-only saved-library context, but it never states exclusions, prerequisites, or which sibling tool to choose instead.

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