From the source SKILL.md

L4G (langage de 4ème génération), also called "X3 script", "4GL", "Adonix", or "SAFE X3 script", is the proprietary scripting language of the Sage X3 / Sage Enterprise Management ERP. It's what you write in .src (source / subprograms) and .trt (treatment / processing) files to customize screens, validate data, orchestrate transactions, call reports, and extend business logic on top of the X3 standard.

What this skill does

Sage X3 L4g is a community-contributed Claude Code skill in the identity-access sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sage-x3-l4g/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Sage X3 L4g Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

How do I install the Sage X3 L4g Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/sage-x3-l4g/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Sage X3 L4g skill do?
Write, read, debug, and review Sage X3 V12 4GL code — also called L4G, X3 script, Adonix, or SAFE X3 scripting. Triggers on any mention of Sage X3 development, files with extensions .src, .trt, .adx, .adp, or L4G-specific syntax like [M:...], [F:...], Trbegin, Readlock, Funprog, Subprog, Class, Method, Public, Private, this, Call...From, Onerrgo, Default File, Mask, Inpbox, Infbox, Errbox, Gosub, fstat, adxlog, UPDTICK, or three-letter uppercase table abbreviations (BPC, ITM, SOH, GACC, etc.).

Also use proactively when the user pastes L4G code even without naming it — the bracketed-class syntax, French/English mixed keywords, and `:#` comments are diagnostic.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Sage X3 L4g skill?
Use Sage X3 L4g when your Claude Code task falls under the Security category — specifically in the identity access area.

Browse related skills at /category/security/.
What is a Claude Code skill and how does the Sage X3 L4g skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Sage X3 L4g is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
