"Nothing clever": dev's AI rewrite was just relentless practical cleanup
lucasmeijer · x · 2026-10-20
Wrapping up his agent-driven rewrite thread, Lucas Meijer demurs that the changes were "nothing super clever, just lots of 'get the clowns out of the car' style improvements" — unglamorous removal of waste. The thread as a whole is a low-cost, high-output agentic engineering case: a weekend rewrite, 2/7 of a $200 subscription, +5-12% from downgrading Gzip, and agents handling the unreleased Jai language without a hitch.
