The premise
Strict-mode migrations stall when teams try a big-bang. Claude makes the per-file work tractable.
What AI does well here
- Infer parameter and return types from usage
- Suggest a per-file enable order by blast radius
What AI cannot do
- Reason about your runtime invariants the types ignore
- Decide when 'any' is the honest answer
