Question
You're adding a feature to a 600k-line monorepo. One engineer's plan: feed the entire repo into the model's context window every request 'so it has full knowledge.' Another: build a retrieval layer that pulls only relevant files. The task this week is a focused change to one service's auth middleware. Critique both approaches and say how you'd actually scope the context for THIS task.
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.
