Use when building a Unity 6.3 level or open world: terrain from code or heightmaps, procedural islands, erosion, splat and foliage rules, trees and grass, ProBuilder graybox, level gym, modular kit and prefab placement, set dressing, landmarks and player guidance, the island's edge, spline roads, WFC, fog, additive scene streaming, or a world that hitches, pops in, leaks memory or runs slow on mobile.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Unity world building (level and environment artist) Expert world building is structure first, then generated content that can be regenerated, then proof: the character fits every space, the camera fits every doorway, the player can reach every space and walk back, the edge of the world holds content, and the worst viewpoint holds the frame budget in a Player. An agent without a mouse does all of it through `TerrainData`, the ProBuilder API, `PrefabUtility` and scene APIs, then checks with raycasts, NavMesh paths, captures, a profiling tour and a Player probe. Target: Unity 6000.3.21f1, URP 17.3, ProBuilder 6.1.2, Splines 2.9.0, AI Navigation 2.0.14. If a sibling skill named here is missing from your available skills, ask the user to install it (`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and flag the gap. **REQUIRED BACKGROUND:** scenario-unity-expert (channels, review loop, 6.3 traps). Import its toolkit; this skill adds [`scripts/ut_world.py`](scripts/ut_world.py), C# jobs in [`scripts/AgentKit/World/`](scripts/AgentKit/World/) and a runtime assembly in [`scripts/Runtime/World/`](scripts/Runtime/World/). …

How to install
mdr add scenario-labs/skills/scenario-unity-world-building@sha256:5fc8188a13ae9ba7The line at the top of this page pins the label git:20260926.9ac7861, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
