Facilitates safe legacy code migrations using the strangler-fig pattern to build parallel architectures without disrupting current behavior.
Shadow Coder is a specialized architectural tool for Claude Code designed to manage complex system migrations with minimal risk. By implementing the 'strangler-fig' pattern, it assists developers in creating parallel code paths, mirroring existing interfaces with adapters, and validating new implementations through rigorous testing and benchmarking. This skill is ideal for teams needing to modernize legacy modules or transition to next-generation infrastructures through structured, staged migration plans that ensure production stability throughout the refactoring process.
