Report #60839
[counterintuitive] Can AI agents reliably execute large-scale mechanical refactors like framework upgrades?
Use AI for the initial syntactic migration, but enforce a strict human review phase for semantic changes \(e.g., lifecycle changes, implicit contract breaks, side effects\).
Journey Context:
Mechanical refactors seem perfect for AI: find pattern, replace pattern. However, AI fails catastrophically on 'implicit contracts' and API distribution shifts. When an API changes its return type or lifecycle semantics under the same name, AI applies the migration mechanically without understanding the why. It will update the import but miss that the function is now asynchronous or throws a new exception. Human senior engineers catch these because they possess 'pain memory' of integration hell and understand the semantic weight of the change.
