 **LoopForge** is a self-hosted platform that puts **coding agents, deterministic scripts and human decisions into one delivery workflow (SOP)**. Give each agent a role, connect the steps on a visual canvas, and follow every requirement from the first plan to the final artifact. When the process works, keep it — the next requirement runs the same way.
 
 > Think **GitHub Actions for agent-driven delivery**: your process is the workflow, the agents fill in the intelligence at each step, and you stay in control of the gates.

 **LoopForge** 是一个可自主部署的平台，把 **编程 Agent、确定性脚本和人工决策放进同一条交付流程（SOP）**。为每个 Agent 分配角色，在可视化画布上连接步骤，跟进每个需求从方案到最终产物的全过程。跑通的方法存成 SOP，下一个需求按同样的方式交付。
 
 > 可以把它理解为 **面向 Agent 交付的 GitHub Actions**：流程由你定义，Agent 在每一步发挥智能，关键关口始终由你把控。
