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.

13## Operating Mode
14 
15- Query skills (`decal_get_info`, `decal_find_all`) are `SkillMode.SemiAuto` — they run in all three modes without grant.
16- Mutating skills (`decal_create`, `decal_set_properties`, `decal_set_properties_batch`, `decal_ensure_renderer_feature`) are `SkillMode.FullAuto` — under **Approval** they need user grant (grant triggers one server-side execute returning the result); under **Auto** / **Bypass** they execute directly.
17- `decal_delete` carries `SkillOperation.Delete` and is **auto-forbidden** in Approval / Auto modes (NeverInSemi). Only **Bypass** or the user-managed **Allowlist** can run it.
