this may break some assumptions i hold.
three other engineers (all capable with ai) attempted this same task but in typescript and failed
lots of variables, but interesting outcome!

Gave my agent a task, but deleted all the typechecking and linting setup first. Told him to do it in plain JS. Just some E2E tests to guide.
Never before have I seen him run so free 🥹
Bounding around, unshackled. No wheels spinning. Barely burning tokens. Just. Free. 🐶
