Use when an agent drives Unreal Engine 5.8 on a Mac for any task: Editor Python (the unreal module), headless UnrealEditor-Cmd -run=pythonscript jobs, Epic's Unreal MCP server, the Remote Control API, console commands and cvars; when a script breaks on 5.8 (EditorLevelLibrary, Remote Control calls refused, Substrate materials black, MRQ presets); when a level, material, shot or build must be judged by numbers and a screenshot before it is called done; or when a brief must go to the right…
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
# Unreal expert (technical director and agent protocol) Expert Unreal work is a loop run against numbers: set the budget, build one stage, measure it, look at it, fix it, then advance. An agent without a mouse gets there by choosing the right channel for each action, working like the Details panel (one transaction, explicit saves), and never trusting its own eyes alone. This skill is the protocol, the shared toolkit in [`scripts/`](scripts/), and the map to the team. Target: UE 5.8 on macOS Apple Silicon. 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. **Status (2026-09-24):** UE 5.8 is not installed. Every in-engine call in `scripts/` and `references/` is **not yet run in Unreal**. The pure-Python parts ran offline and pass (eight test files, 314 checks on Python 3.14, 311 on 3.9). First action once the engine is installed: `tests/code/unreal-expert/run_all.sh --live` with `UE_TEST_PROJECT` set to a scratch project, then [`references/ue-5.8-traps.md`](references/ue-5.8-traps.md) section 7. ## 1. Execution channels …

How to install
mdr add scenario-labs/skills/scenario-unreal-expert@sha256:03646b5f57b86869The 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.
