This is God of Prompt. New home, same mission.
I share the prompts and systems I actually use to run business, marketing, build agents, and ship real work with AI. No "10 tools" threads.
Real frameworks, with receipts. What you get by following:

Loop engineering: design loops that prompt agents; unattended loops fail.
By

about loop engineering. everyone's saying the same thing this week. you don't prompt agents anymore, you design loops that prompt them. here's the job that loop hands right back to you. a loop running unattended is also a loop failing unattended. loop engineering takes you

🚨 Multi-Agent – Lite Agent Swarms – Optimize Cost On Large Agentic Loops
— Abacus.AI (@abacusai) 8 juin 2026
After a lot of experimentation we have open-source AI agent swarms live!!
– Opus 4.8 and GPT 5.5 do the planning
– Deepseek flash and Gemma do the work
– Perfect for multiple parallel tasks
– 10x cheaper… pic.twitter.com/ZzKiyiFl7JMulti-Agent – Lite Agent Swarms – Optimize Cost On Large Agentic Loops After a lot of experimentation we have open-source AI agent swarms live!! – Opus 4.8 and GPT 5.5 do the planning

By
–
Agent loops are not a default, even if it's viral.. They only work when the task repeats, the agent can run the code, and something inside the loop can reject bad output. Miss that gate and you are just automating token burn.
