Understanding AI project — Kiran's 2x2 from experience: clear goal + short context ≈ 90% success; clear goal + long context still works very well but sometimes mixes 2-3 ideas and needs reminders; vague goal + short context is decent and can become clearer through interaction; vague goal + long context fails every time. This creates a useful tension with the simple claim that context length alone causes failure: in Kiran's own experience, long context is tolerable when the goal is clear, while ambiguity and long context together are disastrous.
