Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Still early. Manus is more flexible for less money.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
