For developers juggling more repos than working memory allows
You know the feeling: you open a side project after two weeks and stare at the code wondering what you were even trying to do. ContextOS exists so that moment takes 30 seconds instead of 30 minutes.
What breaks without it
Context lives in your head during a coding session and mostly leaves it by the time you're back. Commit messages capture the "what." Nothing captures the "why I picked this over the obvious alternative."
How developers use ContextOS
Log a quick session note before closing the laptop: what you did, what's blocked. Record architectural decisions with the reasoning, not just the choice. Get an AI-generated resume brief the next time you open the project. Keep a running list of "ideas for later" without cluttering your ticket tracker.
Where it fits with your existing stack
Keep GitHub Issues or Linear for tickets. ContextOS sits one layer up, holding the reasoning and history that ticket trackers were never designed for.
