Preview removing playlist indices

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

Annotations cover safety traits (destructiveHint=false, idempotentHint=false, openWorldHint=true), lowering the bar, but the crucial "preview" semantics are unexplained: what staging means, whether anything is mutated now, how the preview relates to a later commit, and how index shifting affects multiple removals. That is the most important behavioral fact and it is absent.

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, so it is efficient. The terseness is arguably under-specification rather than true conciseness, but nothing is wasted.

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 explained, but for a batch, order-sensitive preview mutation tool the description omits the preview lifecycle and index-shift behavior, leaving an agent unable to use it correctly in the larger 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 compensate. It only hints that indices are "current" positions and that multiple are involved (plural), but says nothing about playlist_id, index validity, the 500-item cap, or ordering effects when removing several indices at once.

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?

The description states a specific verb ("Preview removing") on a specific resource (playlist items) with a scoping qualifier ("by current indices") that distinguishes it from the by_id/by_ids siblings. It is clear what the tool does without opening the schema, though it never names the playlist_id argument or the 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?

There is no when-to-use, when-not-to-use, or alternative routing guidance. The description never mentions the preview/commit workflow (e.g. that this stages an action to be later applied via tidal_commit_action) nor when to prefer by_id/by_index/by_ids variants over this one.

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