Hitting Single-Agent Limits: Devs Weigh Costs of Moving to 3-Agent Workflows
GiLA994 · reddit · 2026-08-07
A developer shared their experience using OpenCode and DeepSeek to manage a large codebase. The current single-agent loop (analyze, review, code, test) works well within a few hours of free tier limits, but struggles with instruction forgetting (e.g., unauthorized commits) and lacks specialization over long sessions.
The author is considering upgrading to a 3-agent workflow (Manager, Coder, Reviewer) to solve review bias and instruction drift. However, concerns are raised about the cost: is it mandatory to subscribe to expensive, different models (like Claude and Codex) for each agent, or can a single model handle all roles? Furthermore, how drastically will inter-agent communication increase token usage and shorten the available usage time?
