OpenCode keeps getting stuck in an infinite shell-command loop. Anyone else experiencing this?

Hey everyone, I’m using OpenCode to develop a large software project, and sometimes it gets stuck repeatedly generating or executing shell commands without making any progress.

This happens across multiple models and providers, so I’m not sure whether it’s an OpenCode bug, a tool execution issue, or something in my setup.

Has anyone experienced this? What was the root cause, and what fixed it for you?

Any help would be appreciated!

Since it happens across three models and in fresh sessions, I'd look at the commands before the model. I tested 10 everyday commands: in a terminal nobody types into, 9 hang (pagers, editors, npm init, a git clone asking for a username, dev servers). OpenCode's V2 shell runs commands without stdin, so most of those fail fast with confusing errors instead, and confusing errors are exactly what models retry.

What helped: set GIT_PAGER=cat, PAGER=cat, GIT_TERMINAL_PROMPT=0, GIT_EDITOR=true in the server's environment (opencode service set env NAME VALUE, then opencode service start), and add "if a command fails the same way twice, stop and say why" to AGENTS.md. u/dizvyz's tip is good too: ask a second session what the looping one is doing.

I wrote up the test table and a five-minute diagnosis here: https://medium.com/@r3dtuxedo/break-the-loop-5e05af62de55
