Section 1
The premise
Tab-completion AI sees only nearby code. It can't reason about your whole project but excels at finishing the next line.
What AI does well here
- Predict next 1-3 lines from local context.
- Complete repetitive patterns (tests, types, getters).
- Match local code style and naming.
- Suggest imports for visible references.
What AI cannot do
- See files outside the open tab without explicit context.
- Refactor or reason architecturally — that's chat work.
