The 'shift' skill is a highly structured framework for orchestrating software migrations and modernization. It provides comprehensive documentation and automation strategies for framework jumps (React 19, Next.js 16, Svelte 5, Spring Boot 4), language transitions (JS to TS, Python 2 to 3), and database evolution. The skill emphasizes best practices like the Strangler Fig pattern, AST-based codemods, and behavioral equivalence testing. No malicious patterns, obfuscation, or unauthorized data access were detected; the skill proactively includes security advisories regarding compromised packages (e.g., the 2026 Axios supply chain alert) and promotes the use of official, trusted migration tools.
