List favorite mixes

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds one behavioral trait beyond them: 'page through' signals paginated, multi-call retrieval. It does not describe default page size, iteration termination, or ordering behavior, which are relevant for a list tool with limit/offset.

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?

One short, front-loaded sentence with zero filler — the resource and scope lead. It is efficient, though the extreme brevity leaves meaningful gaps that the other dimensions penalize.

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 4 undocumented parameters and no output explanation required (an output schema exists), the description should at minimum cover pagination/ordering semantics. Instead it supplies only a paging hint, leaving an agent unable to predict result ordering or how to choose limit/offset sensibly.

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% for all four parameters, so the description carries the burden. 'Page through' loosely gestures at limit/offset but says nothing about the order enum values (DATE, MIX_TYPE, NAME), order_direction, or the 1-100 limit bounds. Most parameter meaning is left undisclosed.

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+resource ('Page through mixes') and scopes it to 'saved in My Collection', which distinguishes it from tidal_browse_mixes and from sibling favorites lists for tracks/albums/artists/playlists/videos. It stops short of naming those siblings explicitly, so an agent must infer the distinction from the scope phrase.

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?

'saved in My Collection' implies the usage context (only user-favorited mixes, not catalog browsing), but there is no explicit when-to-use or when-not-to-use guidance, and no alternative tool is named. The agent can infer the boundary but must do the work itself.

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