Expensive models think, cheap models implement

GPT models plan via CloudHarness MCP; Pi/OMP implement with DeepSeek V4.1 Flash/GLM-5.3 via OpenCode Go for ~$10/mo.

Prompt for your agent

Goal: Route thinking to strong models and implementation to cheap ones.
Setup: agents used in source: Pi, OMP (oh-my-pi), OpenCode; tools/MCPs stated: OpenCode Go, CloudHarness MCP.
Steps:
1. Use expensive models for brainstorming, analysis, architecture, design and planning.
2. If they need to inspect a repo, connect them via CloudHarness MCP.
3. Throw the plan to Pi/OMP and let cheap models implement.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
