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 VFX (Niagara, Chaos destruction, VFX critique) Expert level means an effect that tells the player the truth (where it hurts, when it is over), costs what its gameplay class allows across the whole world, and is proven by per-thread numbers on the target core count plus captures scored against a written rubric. Python cannot author Niagara emitters or modules (5.8 API): the agent works through templates with a User parameter contract, Material Instances, Effect Types and Dataflow recipes, and escalates the few graph edits as precise GUI requests. 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-unreal-expert (channels, review loop, 5.8 traps). **Status (2026-09-24):** Unreal is not installed. Offline checks pass (`python3 tests/code/unreal-vfx/run_all.py --offline`); every in-editor snippet is **not yet run in Unreal**; `job_00_vfx_probe.py` answers the `[verify]` names. ## Stance (the expert delta) …

How to install
mdr add scenario-labs/skills/scenario-unreal-vfx@sha256:01f9aa86eb22b642The 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.
