tl;dr: To avoid the cognitive debt of AI-generated code while still benefiting from LLMs, the author instructs their coding assistant to only propose changes in chat, then manually retypes every line into their project. This makes them roughly 2x faster instead of 10x, but forces comprehension, catches hallucinations, and builds a mental map of the codebase—mirroring the old advice to type out example code rather than copy-paste it.
