When to use

Use this skill when modernizing a legacy codebase โ€” migrating off an old framework or language, decomposing a monolith into services, replacing an EOL runtime, or rewriting a tangled core module safely. It is designed for large systems where a big-bang rewrite is too risky. Trigger when the user mentions strangler fig, incremental migration, legacy modernization, monolith decomposition, or platform upgrades.

Inputs to gather

  • The legacy system's architecture, entry points, and deployment model
  • Business-critical paths and the cost of downtime
  • Test coverage level and whether end-to-end tests exist
  • The target architecture, language, or framework
  • Integration points
