Are you making calls to LLMs and ML models in your code? Is your code awfully sequential™? Is your code unable to stream data?

Look no further! Stephen (@stephenmell.bsky.social), Osbert, Steve, and I came up with a solution for you! Read further if you suffer from the above issues ⬇️

People use LLM agents to interact with (access/modify) their system and external services. We (@bimalraj.bsky.social, @samkumar.bsky.social, and Sai) think this can be a bit dangerous 💣⏲️💥 so we wrote a paper (arxiv.org/pdf/2506.13028) on system guardrails for such agent-driven interactions!

An article written just came out covering our latest work on semantic-driven static analysis for shell script correctness (www.infoworld.com/article/3977...). There will also be a presentation at HotOS on Thursday (sigops.org/s/conference...) for anyone who is there!
Static analysis proposed to ‘rehabilitate’ shell programs
Semantics-driven static analysis could be used to improve the safety, correctness, and performance of Unix, Linux, and macOS shell scripts, researchers say.
