I've had my share of good and bad experiences, one section of an existing project more than 90% ai created. How you say things is equally important to the context you provide, partly because the agents will start trying to decide what is and is not good context, which they are unreliable in doing, even after you give them the limited context and tell them not to edit other files or bring in more context. For example, if you use a lot of colloquial phrases, you activate that area of the network, taking away from using other parts (MoE activation, also lower level too)

They are not good readers (see research results around context collapse and context poisoning)
