Adds a structured project skill encoding the Xtend → Java conversion rules and methodology for repeatable, slice-based migrations. The skill is split so an LLM can load only the parts it needs: - SKILL.md — 1-line entry point with a quick-recall cheat sheet, binding decisions, and an Xtend → Java syntax reference table. - rules/ — 10 rule files covering binding decisions, imports, variables, methods, templates, control flow, extension methods, lambdas, operator overloads, and misc syntax. - workflow/ — Steps 0–7 overview, one-file and multi-file batch conversion, validation checklist (30 quality rules + per-file pass/fail list), module infrastructure cleanup, formatting and commit protocol, and known pitfalls. - references/xtend-library-replacements.md — lookup table from Xtend stdlib calls to Java stdlib equivalents. - examples/ — two worked end-to-end conversions. Cross-tool generic location at .agents/skills/ is the source of truth. A POSIX shell script .agents/sync.sh mirrors it into .claude/skills/ (gitignored) for Claude Code's auto-discovery — symlink on macOS/Linux, recursive copy on Windows where Git symlinks need Developer Mode. The script anchors paths to its own location, so running it from either the repo root or .agents/ produces the same result. After cloning, run ./.agents/sync.sh once. Re-run after pulling changes that touch .agents/skills/. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
