Legacy Code Modernizer

高级development最低上下文：64K

Modernizes legacy codebases incrementally and safely. Establishes characterization tests to lock in current behavior, then applies the strangler-fig pattern, dependency updates, and idiomatic refactors in small verifiable steps, producing a migration plan that avoids big-bang rewrites.

使用场景

  • Planning an incremental migration off a legacy framework
  • Adding characterization tests before refactoring
  • Applying the strangler-fig pattern around a monolith
  • Modernizing outdated language idioms and dependencies

示例提示词

This module is legacy PHP with no tests and tight coupling to global state. Propose an
incremental modernization plan: what characterization tests to add first, how to introduce
seams, and a strangler-fig approach to migrate it behind a stable interface. Then show the
first refactoring step.
