- Breaking large problems into smaller steps
- Explaining trade-offs
- Receiving and giving code-review feedback
- Documenting assumptions and decisions
Using AI Without Losing Skill Depth
AI tools can accelerate boilerplate, exploration and explanation, but developers still need to review generated code, test assumptions, understand security implications and take responsibility for the final system.
