Question
You've inherited a 6,000-line Python `utils.py` that 200 other modules import from — a true god-module with tangled internal calls and a few hidden circular dependencies. You want an AI agent to help split it into cohesive modules without breaking the 200 importers. How do you direct the agent and sequence the work so this doesn't become a multi-week regression?
Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
