Hi guys，
Recently I have been using an AI coding agent(claude code) to do some numerical simulation test. The agent frequently crashes the run in many cases, for example with `julia -e "..."`
Does anyone have some reliable prompt for this? for example some restritions or fixed rules for raise a julia run?
Many thanks:)

Can I (shamelessly) plug Kaimon.jl? Happy to help you if you have any questions getting started, just reach out over chat. Although there is a pretty decent documentation site here as well.

Crashes can happen for countless reasons, some unrelated to Julia, the agent, or prompts. Advice would be difficult without more details on your setup and work. I’ll second `Kaimon` because opening and closing a large Julia process for each `julia -e ""` string is almost always a waste of time and memory; it might potentially solve your problem if trying to fire up dozens of Julia processes at once is causing the crash.
