MigFlow: Contracts for AI Migrations — or How to Make AI Not Break Your Legacy

If you've ever asked an AI to migrate Enzyme tests to React Testing Library, you know the pain: all green locally, but production is a dumpster fire. MigFlow's author proposes a fix — sign contracts with your AI.

How It Works

The idea is deceptively simple: you define expected behavior as contracts — formal specs that the AI must obey during migration. No more "it should work™", only hard guarantees.

• Contracts are just JSON schemas or TypeScript types describing inputs and outputs.
• AI gets the task + contract and generates code that's validated against it.
• Result — migration without surprises, almost as if you did it yourself, but faster.

Of course, it's not a silver bullet. If your legacy is a COBOL monolith, contracts won't save you. But for typical tasks like Enzyme → RTL, it's a game-changer.

METABYTE studio's comment: We love when AI does the heavy lifting, but we prefer it doesn't forget to close parentheses at 3 AM. Contracts are a neat way to keep the neural network on a leash, not guessing what it cooked up overnight.
