Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Generate, inspect, dry-run, and statically validate plain FDM `.gcode` from 3D mesh files by orchestrating real slicer CLIs. Use when Codex needs to slice `.stl`, `.obj`, unsliced `.3mf`, `.ply`, `.glb`, or `.gltf` into printer-profiled G-code, discover local slicer backends, inspect whether a mesh is slice-ready, or validate generated G-code before any printer-specific handoff.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'gcode' ] || [ -L ~/.agents/skills/'gcode' ]; then echo 'A skill folder named gcode already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/autonomous-ai/openharness' "$d" && git -C "$d" checkout --quiet '92aa7660f44e222456248fc9ad16ed0e0f19d43f' -- 'store/agents/text-to-cad/skills/gcode' && mkdir -p ~/.agents/skills && cp -R "$d"/'store/agents/text-to-cad/skills/gcode' ~/.agents/skills/'gcode' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'gcode' ~/.claude/skills/'gcode' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
