Claude Code’s dynamic workflows speed Bun rewrite to Rust, 99.8% pass
Claude’s new dynamic workflow feature lets Claude orchestrate dozens of parallel sub‑agents to perform end‑to‑end code transformations. Using it, Jarred Sumner rewrote the Bun JavaScript runtime from Zig to Rust, producing about 750,000 lines of Rust and achieving 99.8% of the original test suite passing in just 11 days.
