Preview adding playlist tracks

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 largely covered. The description adds useful context that this is a preview (no immediate mutation) and that the playlist must be owned, but it omits the preview-to-commit workflow and any limits. Note the mild tension between 'preview' semantics and readOnlyHint=false, which the description does not resolve.

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, and the core action and target are stated immediately. It is efficient, though its brevity contributes to the coverage gaps elsewhere.

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, but with 4 parameters at 0% schema coverage and no explanation of the preview/commit pairing, an agent lacks enough to call this correctly and act on the result. The description does not fill that gap.

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 4 parameters. The description covers only track_ids and the playlist (via 'owned playlist'); it says nothing about position, allow_duplicates, the 1-500 track bound, or the 160-char playlist_id limit. With no schema descriptions, the description fails to compensate for the coverage gap.

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 (preview adding) and resource (exact track IDs to an owned playlist), which implicitly separates it from tidal_preview_add_track_by_isrc_to_playlist. However, it never names that sibling explicitly, so the differentiation requires the agent to infer it from 'exact track IDs'.

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 beyond the word 'Preview'. It never explains that this is a non-committing step that must be followed by tidal_commit_action, nor when to prefer it over tidal_preview_add_track_by_isrc_to_playlist. The 'owned playlist' constraint is the only contextual hint.

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