After heavy use of ultracode, I once again deeply feel the irreplaceable greatness of Claude Code. Furthermore, the trend of Harness development is self-evident — less human intervention, more agent autonomy, and longer unsupervised runs:
- Cursor’s yolo mode
- OpenSpec’s SDD
- Ralph Loop
- Karpathy’s autoresearch
- Claude Code’s plan mode
- Codex’s /goal
- Claude Code’s ultracode (dynamic workflow)
- …
Ralph Loop is likely a turning point: before Ralph Loop, it was competition in model iteration; after Ralph Loop, it becomes competition in model + harness.
