Same boat. 5 agents is my hard limit, past that I lose the thread and it stops being guided coding, turns into vibe coding. I lean into the context switch instead of fighting it. Plan a large task, kick the agents off, walk away. My rule is whatever I switch to has to be little productive than watching tokens stream or shorts. usually a workout or a research video. Reframes the wait for me. For review I go in other direction: spin up 50 to 100 review agents to audit everything and rank issues by severity. I work through the blockers manually and read the actual diffs. Handles most of the bug compounding problem you mentioned. It’s a kind of flow. Definitely not the same as writing the code ourself, nothing is. Just the closest substitute I’ve found in this era
