I had very similar experiences. I had some incredibly wild "successes" in fixing some company systems even though I had just joined the company and I was not familiar with such systems prior to joining.

My "secret" is that I just read the service's documentation (the fine manual) and did what the documentation described.

It's wild how some people's nowadays go around and around mindlessly trying stuff that the LLM of the day suggested, without actually learn enough to *reason* about internals of services and systems.
