I still don't understand why people are still building agents as a straight line you write "do A, then B, then C." half those steps never needed to wait on the one before them. you just paid for the wait anyway, every single run one test tells you everything, ninety seconds, before you write a single line of orchestration code: walk your workflow step by step → ask one question at every seam → does this step actually need the last one's output if yes → keep the order, it's a real edge if no → cut it, that wait was fake and cost you nothing but time, on purpose, this whole time now split what's left into the pattern that actually scales: fan out → one agent per independent piece, all running at once reduce → plain code, zero model tokens, just flatten and dedupe verify → a fresh agent with no memory of the work, one job: try to kill it synthesize → one final agent writes the answer from what survived here's the part that breaks every setup people skip: the verifier can never share context with the worker → give it the same conversation and it's not checking anything, it's agreeing with itself in a different window, wearing a different name one rule, no exceptions → worker and verifier, separate context, always most people build the fan-out, call it done, and never notice the thing checking their work has been the exact same hand the entire time ninety seconds to run the test. you never queue a fake wait again
