So leave emotion at the door and make your words count. Voice your frustrations at the stress doll next to your monitor, sure, but spending tokens on them us just wasting time and money. Explicitly typing out your exasperation will not get you closer to whatever it is you are trying to accomplish. What can you type that will?
Laser focus: clearly, concisely explain what is wrong right now, and how you want it solved. Then do that again until all the moles have been whacked. If the AI is stuck in a sycophancy loop, start a new clean session. Do this frequently anyway: every turn in the same session charges for all preceding conversation again /and/ degrades the LLM's performance.
