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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description usefully clarifies the scope of destruction — folder assignment, not the asset itself — which softens an otherwise alarming destructiveHint. It stops short of saying where assets end up afterward or what the response contains, so it adds moderate value only.

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?

One lean sentence with no filler, front-loading the action and resource. It could stand a second sentence on scope or siblings, but nothing present 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. For a destructive mutation tool, however, the definition leaves open what happens to the removed assets, whether asset_ids is optional, and how it differs from sibling removal tools — gaps that annotations alone do not close.

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 coverage is 50%: workspace_id is documented in the schema, but asset_ids has no description anywhere. The phrase 'one or more assets' faintly implies an array of asset ids, but neither the description nor the schema states whether multiple ids are supported, the id format, or that the field is optional. Baseline 3 given partial coverage.

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+resource ('remove assets from folder assignment') and clarifies it untethers assets rather than deleting them, which distinguishes it from delete_asset and assets_delete_many. It does not, however, explicitly name which sibling to prefer or clarify the relationship to remove_asset_playlist / delete_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?

No when-to-use guidance, no prerequisites, and no mention of alternatives such as delete_asset (full delete) or delete_folder. The agent must infer usage purely from the sentence. Also, the description says 'one or more assets' while asset_ids is not in the required list, with no guidance on what happens if it is omitted.

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