Announced on Practical AI by co-founder Hamza Tahir, who frames an agent as "just a while loop that talks to a model, calls a tool, and writes to a filesystem" (Practical AI). Kitaru is an open-source replayable runtime that records every step as a checkpoint, so a failed run resumes from the last saved step instead of restarting. This is the durable-execution pattern from workflow engines finally arriving under agent stacks. If you run long autonomous jobs, you want this before you want a better model.
