0upvotes

Visualize a JavaScript regular expression as a railroad diagram (PNG/SVG) or a Mermaid flowchart by shelling out to the `regulex-plus` CLI. Use whenever the user asks to explain, debug, understand, optimize, or document a regex — especially complex patterns with quantifiers, lookarounds, alternations, or CJK/Chinese characters — and also proactively after you yourself generate or modify a non-trivial regex, so the user can verify it visually. Pick Mermaid for embedding in docs / PRs / chats that render Mermaid natively (GitHub, Notion, Obsidian, mermaid.live); pick PNG for inline image preview anywhere; pick SVG for editable vector documents.

# regulex-plus

Render any JavaScript regex as a railroad diagram saved to a local image file. Wraps the regulex-plus web visualizer in a headless-browser CLI, so it works in any Node environment without manual screenshots.

## When to use

Invoke this skill when **any** of the following holds:

- The user asks to **explain / understand / 解释 / 看懂** a regex.
- The user is **debugging or optimizing** a regex and would benefit from a structural view.
- The regex contains **CJK characters / 中文** — regulex-plus has native CJK width handling that generic visualizers lack.
- The regex has **alternations, nested groups, lookarounds, backreferences, or non-trivial quantifiers** that are hard to read inline.
- You (Claude) just **generated or rewrote a regex** in a code change — offer the user a visual to confirm intent.
