Adds regulex-plus, a Claude Skill that renders any JS regex as a railroad SVG/PNG diagram from the command line.
- Real use case: explaining/debugging complex regex — especially CJK or with deep alternations — is one of the most common pair-programming tasks where a visual cuts orders of magnitude of confusion. Also works for verifying regex Claude generates itself.
- Skill format: ships with
SKILL.md at repo root + Node CLI (bin/regulex-plus.mjs).
- Tested: smoke tests cover ASCII, CJK, alternation, and quantifier patterns; reproducible via
npx regulex-plus '中文(标点|符号)+'.
- Safe: no destructive operations; CLI writes a single output file.
- Portable: works wherever Node + Chromium does.
