Design component surfaces and elevation states.
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
# Surface Shadow Material Systems ## Use This Skill Use this skill for design surfaces, shadows, borders, and material depth with restraint. ## Scoped execution Apply the [shared web contract](../website-operating-rules/references/scoped-web-contract.md) once when execution crosses phases; reuse it if already read. Load only the specialist guidance relevant to the requested surface and deliverable. ## Required Reference Read [references/surface-shadow-material-systems-guide.md](references/surface-shadow-material-systems-guide.md) before making architectural or visible UI changes with this skill.

How to install
mdr add thegoat395/codex-skills/surface-shadow-material-systems@sha256:7432464f70f647c9The line at the top of this page pins the label git:20260905.f7824ba, 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.
