You can try, but you can’t make it correct. My ideal is to write code once that is bug-free. That’s very difficult, but not fundamentally impossible. Especially in small well-scrutinized areas that are critical for security it is possible with enough care and effort to write code with no security bugs. With LLM AI tools that’s not even theoretically possible, let alone practical. You will just need to be forever updating your prompt to mitigate the free latest most fashionable prompt injections.
You can make it more resistant to overwriting instructions at least
