⚠️ 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.

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)

For Claude Code:

git clone https://github.com/Ganbin/4d-development-skill.git
cp -r 4d-development-skill ~/.claude/skills/4d-development

Then restart Claude Code. The skill activates automatically when working with 4D files.
