Preview removing a favorite playlist

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is partly covered and the "Preview" wording is consistent with a staged, non-destructive dry run. The description adds the multi-playlist scope but never explains that the action is staged and must be committed separately, nor that it affects the user's collection state. No contradiction with annotations.

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 action front-loaded and zero filler. It is well sized, though it omits the workflow context that would have earned a top score.

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 shape need not be described. But for a staged mutation in a preview/commit family, the description leaves the commit step and the effect on My Collection entirely unexplained, which is the key thing an agent must know here.

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?

Description conveys "one or more playlists," which matches the required playlist_ids array and its minItems/maxItems multiplicity. With 0% schema description coverage, it does not clarify ID format (TIDAL numeric vs. UUID) or the 500-item cap, so it only partly compensates.

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 ("removing ... playlists from My Collection") with scope ("one or more"), distinguishing it from the non-preview deletion siblings. It does not, however, name or contrast with the actual mutation/commit sibling that would carry the change out.

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?

No when-to-use guidance, no prerequisites, no mention of the alternatives it pairs with. For a tool named "preview" inside a family that also has commit tools, the absence of any statement about when to preview vs. when to commit is a real gap.

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