AI for Coding: Sweep a Codebase for a Deprecated API
Drive a multi-file refactor by having AI find every caller of a deprecated function and propose a targeted migration patch per site.
8 min · Reviewed 2026
The premise
Deprecation cleanups stall because finding all callers and updating each correctly takes scarce attention; AI can do the discovery and draft per-call-site patches.
What AI does well here
Find call sites including dynamic and string-based ones
Propose minimal replacement code per site
Group sites by replacement pattern
Draft a single PR description summarizing the sweep
What AI cannot do
Detect call sites built from runtime metaprogramming
Know which call sites are actually dead code
Verify that the new API behaves identically in your environment
