I am vibecoding an app now, so I started with docs in the repo just because everything is in the repo. But mow I’m relying on this even more. The reason is that problems with session happen - context compacting, being out of tokens mid-implementation and continuing later, etc. So on several occasions, the agent started writing a feature based on my detailed explanations, and finished however it felt like finishing, because my detailed explanations were lost. So now it’s alvays:

• Keep my ToDo exactly as I phrased it, IN A FILE
• Plan out the implementation, IN A FILE
  Now, there’s a zero chance any details of my request will be lost completely. And even if something happens mid-implementation, the chat has everything to track back and see what was done, and what wasn’t. We already had a steict TDD policy, so now both tests and docs are there long before any coding actually happens
