Surely people have found patterns that work reasonably well, and it's not "everyone is completely on their own"? I get that the scene is changing fast, but that's ridiculous.
But your codebase is unique. Slop in one codebase is very dangerous in another.

I was mostly working off "well I could ask claude to look at my code for security problems, i.e. 'plz check for security holes kthx', but is that really going to be the best option?". if "yes", then it would kinda imply that all the customization and prompt-fiddling people do is useless, which seems rather unlikely. a premade tool is a reasonable starting point.
You can do that in conjunction with trying things other people report, but you'll learn more quickly from your own experiments. It's not like prompting a coding agent is expensive or time consuming, for the most part.
