Cross-Technology AEC Integration — Claude Skill Package

15 deterministic skills for bridging AEC technology boundaries with Claude. Each skill covers exactly ONE technology boundary. English-only. ALWAYS/NEVER deterministic language.

---

Why This Package?

AI fails most at technology boundaries. When you ask Claude to move data from IFC to ERPNext, transform BIM coordinates to GIS, or containerize an AEC tool stack — it needs to know BOTH sides of the boundary. This package provides that knowledge.

Each skill documents:

• Side A — the source technology (APIs, data formats, conventions)
• Side B — the target technology
• The Bridge — how data transforms between them, and what gets lost

Installation

Option 1: Clone directly

git clone https://github.com/OpenAEC-Foundation/Cross-Tech-AEC-Claude-Skill-Package.git

Then add to your project's .claude/settings.json:

{
  "skills": {
    "sources": [
      "/path/to/Cross-Tech-AEC-Claude-Skill-Package/skills/source"
    ]
  }
}

Option 2: Use alongside other AEC packages

This package is designed to work WITH other AEC skill packages:

Package	Skills	Purpose
Blender/Bonsai/IfcOpenShell	73	3D modeling + IFC
ERPNext	28	ERP/costing
n8n	21	Workflow automation
Docker	—	Containerization
This package	15	Bridges between all of the above

Quality Standards

Every skill in this package:

• Is under 500 lines (SKILL.md)
• Uses ALWAYS/NEVER deterministic language
• Documents BOTH sides of the technology boundary
• Includes references/methods.md, examples.md, and anti-patterns.md
• Specifies exact version numbers for all technologies
• Documents data loss at each boundary
