Multi-agent harnesses vs one strong agent: builder finds the simpler setup wins
duku-95 · reddit · 2026-09-14
A developer shares hands-on skepticism about multi-agent harness architectures: specialized agents for planning, coding, review and testing sound good in theory, but in practice they hit lost context between agents, duplicated work, coordination overhead, conflicting decisions, handoff latency, and the harness itself becoming a debugging burden.
He now prefers one capable agent with strong context and tools plus an orchestrator/planning layer, parallelizing only when genuinely justified—arguing multi-agent setups risk recreating organizational bureaucracy inside AI systems, and asking production users where multi-agent actually beats the simpler stack.
