Tip: TypeScript 7 Made the Verifier Cheap Enough to Run After Every Agent Edit
paddo.dev's July 27 post measures the Go-rewrite compiler on real projects: a 9,140-line Astro blog went 2.56s → 0.32s (8.0x), and a 159,320-line Next.js app went 7.32s → 0.78s (9.8x), with CPU utilization rising from ~156% to 422% while using less total CPU time. The actionable shift: "At 0.78 seconds you don't batch" — wire `tsc` into a PostToolUse hook so it runs after every `.ts` modification, surfacing the error while the reasoning that produced it is still in context. Type errors become continuous sensory input rather than a final gate, replacing more expensive test-harness round-trips.
