 # Improving GPT-4's codebase understanding with ctags
 
 GPT-4 is extremely useful for "self-contained" coding tasks,
-like generating new code or modifying a pure function without dependencies.
-But it's difficult to use GPT-4 to modify code with dependencies
-that are scattered across many files of a codebase.
-To modify such code, GPT needs to see all of these dependencies.
