4D Development Expert Skill
Work in Progress: This skill is being refined based on real-world usage. Feedback and contributions welcome!
A Claude Agent Skill for 4D development, providing expert guidance on ORDA patterns, queries, forms, and version compatibility.
What It Does
Transforms Claude into a 4D development expert:
- Modern ORDA patterns (Entity classes, DataClass methods)
- Classic 4D methods (Arrays, process variables)
- Query syntax (basic to advanced with formulas)
- Data types and conversions
- Error handling (Try/Catch and ON ERR CALL)
- Form development (JSON forms, events)
- Version compatibility (focus on 4D v19.2 LTS)
Installation
Using npx skills (Recommended):
npx skills add Ganbin/4d-development-skill
Manual install:
git clone https://github.com/Ganbin/4d-development-skill.git
cp -r 4d-development-skill ~/.claude/skills/4d-development
cp -r 4d-development-skill ~/.claude/skills/4d-development
Then restart Claude Code. The skill activates automatically when working with 4D files.
