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- **Approval** (default): all mutating skills (`material_create`, `material_create_batch`, `material_assign`, `material_assign_batch`, `material_duplicate`, `material_set_color` / `_emission` / `_texture` / `_float` / `_int` / `_vector` / `_keyword` / `_render_queue` / `_shader` / `_texture_offset` / `_texture_scale` / `_gi_flags`, and the `*_batch` variants) need user grant; grant triggers a single server-side execution that returns the result.
16- **Auto / Bypass**: those skills execute directly.
17- Query skills (`material_get_properties`, `material_get_keywords`) are `SkillMode.SemiAuto` — they run in all three modes without grant.
18- This module contains **no** Delete / PlayMode / Reload / high-risk skills (no NeverInSemi); to delete a material asset, call the `asset` module.
