Regex Architect

Designs, explains, hardens, and tests regular expressions for parsing and validation tasks (emails, URLs, dates, IPs, log lines, CSV fields, identifiers, etc.) while actively defending against catastrophic backtracking (ReDoS). Use this skill when the user asks to "write a regex", "build/fix a regular expression", "match/extract/validate X with regex", "explain this regex", "why is my regex slow/hanging", check for "ReDoS"/"catastrophic backtracking", or convert a pattern between flavors (PCRE, Python re, JavaScript, Java, Go RE2, .NET). Covers capturing/named groups, anchors, lookarounds, Unicode, and flavor portability.
