How does the skill validate the new parallel path?

Shadow Coder follows a specific step to validate new paths using automated tests or performance benchmarks to ensure the replacement meets or exceeds the original's standards.

What is a staged migration plan?

It is a step-by-step roadmap generated by the skill that outlines how to transition traffic or logic from the legacy path to the new path in controlled increments.

Can I use Shadow Coder for API versioning?

Yes, it is highly effective for mirroring interfaces and creating adapters to ensure that new backend logic remains compatible with existing API consumers.

What is the strangler-fig pattern in Shadow Coder?

The strangler-fig pattern is an incremental migration strategy where a new system is built around the edges of an old one, eventually replacing it entirely while maintaining safety.

How does Shadow Coder handle parallel architectures?

It creates isolated parallel paths, such as a _next_gen directory, allowing you to build and test new logic without interfering with existing production behavior.

Facilitates safe legacy code migrations using the strangler-fig pattern to build parallel architectures without disrupting current behavior.

概要

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.
