Yeah! I've been using the interactive modes (e.g. just the "claude" command). The insight by a friend of mine is to have the agent update its own knowledge base regularly. For example, for a first time session, using Claude I would run "claude" in the root of the kernel tree, and then write: /init Find and read the coding style and submitting patches documentation in the Documentation/ directory Always use a build output directory, like "claude-build". This must always be specified with the O= option for make This is a big build machine, so also always use the -j128 option for make Perform a build of the kernel Save anything new you've learned in your CLAUDE.md file Keep all new .md files and temp files in the agentic/ directory Examine git history of commits by Kees Cook over the last 5 years and write out a new .md file that describes his commit log writing style Use this for any commit messages we write Figure out how to run KUnit tests, the docs are in Documentation/ Run the fortify KUnit tests Update your CLAUDE.md with anything new you've learned (Note that I run the agent as an entirely separate user in a Docker container.) The agent acts like an intern who reads VERY quickly, but forgets things regularly. So it has to be both reminded to save new stuff it learns (I break things into separate .md files), and then read them back again after it starts forgetting. It still needs extensive hand-holding, and it's rare that I'm happy with its commit logs, but it is pretty helpful so far. That said I've been focusing on some smaller refactoring work just to feel out how to use it. I have some hints that it would struggle with doing very large scale refactoring on its own, but it's nice to toss it at a huge patch I generated via Coccinelle and say "build this across all our configured archs and fix any compilation failures you encounter" and then go have lunch. ;) -Kees -- Kees Cook
