1> **Before calling any skill in this module:** if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via `GET /skills/recommend?includeSchema=true`) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

11> **Safety**: `cleaner_delete_assets` uses a **two-step confirmToken handshake**. Call without `confirmToken` to preview; call again with the returned token (5-minute TTL) to actually delete. There is no `dryRun` parameter.

15**Operating Mode** (v1.9 three-tier):
16- **Approval** (default): all analyze/query skills (`cleaner_find_unused_assets`, `cleaner_find_duplicates`, `cleaner_find_missing_references`, `cleaner_get_asset_usage`, `cleaner_find_empty_folders`, `cleaner_find_large_assets`, `cleaner_get_dependency_tree`) are SemiAuto — run directly.
17- **Auto** / **Bypass**: SemiAuto and FullAuto run directly.
18- Auto-forbidden in this module: `cleaner_delete_assets`, `cleaner_delete_empty_folders` (both carry `SkillOperation.Delete`). In Approval/Auto these return `MODE_FORBIDDEN` — they are reachable only under Bypass mode or via a user-managed Allowlist entry; the grant flow does **not** unlock them.
