I use this tool every day at work to run different official agent harnesses with subscriptions. The features are plentiful and very useful, upstream development is fast, they accept changes quickly, stable/reliable operation, lightweight. Best of all: it's just a traditional FOSS project, they're not trying to sell you something.
It is created with AI, but I have had no issues using it for months. I'm kind of amazed at how good it is.
