regex-builder
DEPRECATED — Modern Claude models produce accurate, well-explained regex patterns with edge-case test suites natively, including multi-language usage examples. The uplift delta from this skill approaches zero. Retained for archival reference only.
Regex Builder
Transforms matching requirements (positive and negative examples) into tested regex patterns with component-by-component explanations, capture group documentation, edge case identification, and ready-to-use code in Python and JavaScript.
