File contents

Codename One — App and UI Authoring Skill (Claude Code stub)

This file exists so Claude Code can index the Codename One authoring skill. The actual skill content is vendor-neutral and lives in this repository at:

.agent-skills/codename-one/SKILL.md — top-level cheat sheet
.agent-skills/codename-one/references/*.md — deep-dive references
.agent-skills/codename-one/tools/ — runnable Java 17 utilities (isApiSupported, isCssValid, ...)

Read .agent-skills/codename-one/SKILL.md next. All the guidance you need to build, style, test, debug, and port to Codename One is in that directory.
