Preview folder creation

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

Annotations supply readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the safety profile is partly covered. The description repeats 'preview' but never explains the strongest behavioral fact an agent needs: whether this returns a pending action/token to be committed later, or whether a preview mutates anything. That preview-vs-mutation distinction is exactly the context the annotations cannot convey.

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 clean sentence with no waste is structurally fine. But brevity here is under-specification rather than efficiency: the one sentence is the entire definition and earns little beyond the title.

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 this is a mutation-flow tool with 0% parameter coverage, no commit guidance, and no explanation of the preview semantics. Given the dense sibling set of preview_* tools, the definition leaves the agent without enough to call it correctly in context.

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% — neither 'title' nor 'parent_folder_id' carries any description. The description mentions no parameters at all, so it does not compensate for the coverage gap; the fact that parent_folder_id defaults to 'root' is undocumented anywhere.

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 and resource ('preview creating a playlist folder'), which is unambiguous on its own. It does not, however, differentiate itself from the commit counterpart (tidal_commit_action) or from tidal_preview_create_playlist beyond the word 'folder'.

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 statement of when to use this versus tidal_commit_action or the other preview siblings. An agent must infer the preview-then-commit workflow entirely from naming conventions, and nothing tells it that this tool alone does not persist the folder.

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