LoopX: A Control Plane for AI Agents That Have to Keep Working for Days

If you have ever pointed a coding agent at a multi-day goal, you know the failure mode. It is not that the model writes a bad function. It is that on turn 40, the agent no longer remembers what the objective was, which decision you already made, what is out of scope, or what the last run actually proved. The context window rolled over, and the plot went with it. LoopX is an attempt to fix that specific problem. It calls itself "loop engineering for long-running AI agents," and it is a local control plane that sits above your agent runtime rather than replacing it. The one-sentence version Your agent (Codex, Claude Code, Cursor, whatever) executes bounded loops. Something (a heartbeat, a cron job, you hitting enter) triggers the next loop. LoopX holds the state that has to survive between those loops. The project draws the separation like this: Layer Role Codex / Claude Code / Cursor Execute a bounded agent loop: read, write, run commands, respond Goal mode / automation / CLI / TUI Trigger or schedule the next loop LoopX Preserve goals, gates, todos, run history, quota, evidence, handoff state That third row is the whole product. LoopX is not an executor and not an autonomous production controller. It is a state kernel with a CLI. Why "just use a todo file" isn't enough A TODO.md plus a long system prompt gets you surprisingly far. It falls over once any of these become true: The goal changed halfway through, and nothing recorded why . A decision genuinely needs a human, and that request evaporated into a chat message nobody read. Two agents are touching the same repo and neither knows who owns what. The last run claimed success, and there is no artifact proving it. Some work is safe and read-only, some crosses into writes, production, or private data, and the distinction lives only in your head. LoopX makes those things explicit and machine-readable, which is what lets a loop run longer without becoming less accountable. The concepts, in plain English Lifetime goals
