scenario-zbrush-hard-surface SKILL.md skillA
scenario-zbrush-hard-surface from scenario-labs/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when modeling hard surface in ZBrush 2026 (sci-fi helmet, weapon, prop, armor plates, mechanical parts, kitbash, vents, panel lines, bolts, concept to game asset), when using ZModeler, Dynamic Subdivision and creasing, Live Boolean, Knife, Clip, Slice or Trim curves, IMM, ArrayMesh, NanoMesh or Panel Loops, or when edges look razor sharp, a Make Boolean Mesh fails or leaves holes, planes look wobbly, Mirror And Weld erased an edit, or ZRemesher ruins a hard-surface part.
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
# ZBrush hard surface
Hard surface is judged as a result: it reads as manufactured when every edge is clearly straight or clearly curved, planes carry an even highlight, edges are wide enough to catch light and every part could be built (Plouffe, Klimer). The agent builds that language from deterministic operations (primitives, Live Boolean stacks, polygroups as the crease plan, Dynamic Subdivision numbers, ArrayMesh, Panel Loops) and uses clicks and strokes only where nothing else exists. 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-zbrush-expert (bridge, stroke engine, review loop, 2026 traps). Toolkit: [`scripts/zb_hardsurface.py`](scripts/zb_hardsurface.py) (`import sys; sys.path.insert(0, "<this skill>/scripts"); import zb_hardsurface as hs`, then `hs.hs_call("new_part", "cube")`), built on the lead's `zb_ops`, `zb_review`, `zb_audit` and `zb_stroke`. Nothing in it has run in ZBrush yet.

How to install
mdr add scenario-labs/skills/scenario-zbrush-hard-surface@sha256:728dbd8745f47f90The 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.
