Preview removing a favorite mix

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

Annotations already declare destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the safety profile is covered. The description adds only 'one or more' and 'My Collection' — it never explains that this is a dry-run that changes nothing until committed, nor what the preview result contains, so it adds little behavioral context beyond the title.

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, front-loaded with the operation, with no filler. It is concise to the point of under-specification, but structurally clean.

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?

An output schema exists, so return values need not be described. However, for a preview tool in a preview/commit pipeline, the missing link to tidal_commit_action and the undocumented mix_ids format leave the agent without what it needs to actually use the tool correctly.

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 the single mix_ids array. The phrase 'one or more mixes' only echoes the schema's minItems=1; it does not document the 500-item maximum, the expected ID format, or whether these are TIDAL mix IDs.

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: 'Preview removing ... mixes from My Collection.' The resource (mixes) distinguishes it from the sibling preview_unfavorite_track/album/artist/playlist/video tools, so an agent can route correctly. It stops short of explaining what a 'preview' produces, which keeps it from 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 when-to-use guidance and, critically, no mention that a preview must be followed by tidal_commit_action to take effect — the single most important usage fact for this tool family. The agent is left to infer the preview/commit workflow from the name alone.

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