Claude Code on My Own Blog: 47 Commits in 2 Days, 14 Rewritten by Hand — and METR's Gap Between −19% Reality and +20% Feeling
I handed Claude Code a draft of my own blog and got 47 commits in two days. I rewrote 14 by hand. I unpack why the sense of speed lies (METR: -19% in fact, +20% by feel), why "almost correct" code is the most expensive kind, and how the aviation rule of "children of the magenta line" sets the levels of delegating to AI. Exact prompts, a tool table, verified numbers.
