The premise
AI coding assistants are not magic — they combine a code-trained model, careful context gathering from your editor, and prompt scaffolding to produce completions and chat answers grounded in your codebase.
What AI does well here
- Suggesting completions that match your codebase's idioms
- Answering questions about code you have given the model access to
- Refactoring within a tightly-scoped, well-tested area
- Drafting tests, docs, and small functions from clear specifications
What AI cannot do
- Understand all of your codebase at once — context windows still bind
- Reliably refactor across many files without supervision
- Replace the engineer's responsibility for the resulting code
