Preview removing a playlist item

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the safety profile is covered. The description adds one genuinely useful behavioral fact — the playlist must be owned — but does not explain what 'preview' returns or how it relates to a commit step. No annotation contradiction: 'preview' plus destructiveHint=false is coherent.

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 front-loaded sentence with no filler. Every word contributes to scope or resource identification.

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?

Output schema exists so return values need not be described, but for a preview tool in a large preview/commit family the description omits the single most important context: that this is a non-applied staging call requiring a subsequent commit. That omission leaves an agent likely to mis-sequence the workflow.

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 carry the load. It does clarify that media_id is a media identifier (not an index) and that playlist_id must reference an owned playlist, which is meaningful disambiguation, but it gives no format, length, or ID-syntax detail.

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 (removing), resource (media ID), and scope (one, from an owned playlist). 'One media ID' usefully distinguishes it from the plural sibling remove_playlist_items_by_ids and from the index-based variant, though it never names those siblings explicitly.

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 and no explanation of the preview/commit two-phase pattern that clearly exists in this tool family (tidal_commit_action, tidal_preview_*). The agent is left to infer that 'preview' means nothing is applied until committed.

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