Asana did 5 years of engineering in 2 weeks with 4 Codex agents

been using Codex and Claude Code on client projects for months now but the Asana story still hit different

they had a frontend test migration estimated at 5 years and $6M. four Codex agents did it in 2 weeks for $12K. thats not a typo. twelve thousand dollars

the workflow is what got me. one five sentence prompt. up to four agents running in parallel each on a separate copy of the codebase. an engineer checking in twice a day. thats it

i been doing something similar on a smaller scale. got a client project with a legacy Express backend that needs refactoring. started pointing agents at individual modules. not as dramatic as Asana but the same idea. break the big scary migration into parallel agent tasks and just review the diffs

the thing nobody talks about. the hard part isnt the AI. its writing a prompt specific enough and having tests that catch regressions. Asana had a clear finish line (remove Enzyme) and tests to verify. without that the agents just make a mess

what project have u been putting off because it felt too big? might be time to revisit it
