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.

Triggers

• Creating or editing terrain
• Sculpting or smoothing heightmap
• Painting terrain texture layers
• 创建或编辑地形、雕刻或平滑高度图、绘制地形纹理层

Unity Terrain Skills

Operating Mode (v1.9 three-tier):

• Approval (default): query skills (terrain_get_info, terrain_get_height) run directly. Create/modify skills (terrain_create, terrain_set_height, terrain_set_heights_batch, terrain_add_hill, terrain_generate_perlin, terrain_smooth, terrain_flatten, terrain_paint_texture) are FullAuto — on MODE_RESTRICTED, run the grant protocol; /permission/grant executes the skill server-side and returns the result.
• Auto / Bypass: SemiAuto and FullAuto run directly.
• This module contains no Delete / PlayMode / Reload / RiskLevel="high" skills — nothing auto-classifies as forbidden. To remove a terrain delete the asset via asset_delete (subject to its own forbidden rules).

Note: All sculpt/paint operations require an existing Terrain in the scene, or use terrain_create to generate one.
