The Delegate Pattern: Run Claude Code + Codex + Gemini in Parallel — Zero-Cost Rate Limit Bypass for Multi-Agent AI

Why I Built This

The motivation was simple: AI stops. Frequently.

When running large tasks with Claude Code, you hit Anthropic's rate limits fast. When you add more sub-agents to run in parallel, Claude's own context gets polluted and performance degrades.

I also tried a real-time message bus (agmsg). Multiple CLI windows throwing messages caused confusion. SSE connections dropped, losing notifications. Infrastructure maintenance cost was too high.

Then it hit me: concentrating everything in one AI vendor is itself the problem.
