Preview removing a playlist index

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description's 'Preview' wording adds genuine context beyond the annotations by signaling the action is not applied immediately, but it stops short of explaining the preview/commit workflow or what the preview returns given that annotations imply some non-read-only state change.

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 no filler, and the key scope word ('Preview') leads. It is efficient, though the brevity edges toward under-specification rather than true conciseness.

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. However, for a preview tool living alongside tidal_commit_action, the description omits the crucial fact that the removal is staged and must be committed, and it says nothing about index semantics or playlist_id, leaving the agent to guess at the two-step flow.

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 parameter burden. 'By current index' gives some meaning to the index parameter (a live position in the playlist, implying subsequent indices shift), but playlist_id is never mentioned and the zero-based basis is left to the schema's minimum of 0.

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 names a specific operation (preview removing a single item), the resource (playlist item), and the addressing scheme (current index). It implicitly separates this from siblings like tidal_preview_remove_playlist_item_by_id and tidal_preview_remove_playlist_items_by_indices by emphasizing 'one item' and 'index', but it never names those alternatives 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 guidance on when to choose index-based removal over the four sibling variants (by_id, by_indices, by_ids), nor any note that this is a preview that must later be executed via tidal_commit_action. Usage is only inferable from the tool name.

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