# What will AGI do for Legacy Code Refactoring?

## Overview

Engineering teams at established companies face compounding friction when modifying aging, undocumented codebases. As original authors depart and dependencies deprecate, core business logic becomes locked inside brittle architectures. Engineers must decipher years of undocumented patches just to implement routine updates, turning trivial feature requests into extensive archaeological expeditions.

This technical debt persists because structural modernization competes directly with immediate product deliverables. Existing static analyzers and linters flag syntax issues but lack the semantic context to safely restructure complex business logic. Without comprehensive test coverage to validate system behavior post-migration, teams avoid structural changes and opt for superficial patches that further degrade the architecture.

The primary blocker is the manual extraction of business intent from legacy syntax. Developers must manually map outdated control flows to modern paradigms while preserving undocumented edge cases. Because current workflows rely entirely on human working memory to hold state during a transition, large-scale refactoring remains a high-risk, labor-intensive bottleneck.
