Because most LLMs are just a REST call, it’s a trivial matter to wire them up in a loop over all source files. The fiddly part is finding a good library for enumerating files while adhering to .gitignore and/or “project” file include/exclude rules!

Even very simple prompts can yield very useful outputs.

“Report each bug you spot in this code with a markdown formatted report.” worked better than I expected.

It costs just a couple of dollars to scan through an entire codebase with something like Gemini Flash.
