This issue might be a duplicate of existing issues. Please check:

• Infinite retry loop when StreamIdleTimeoutError occurs during tool input generation #12234: Infinite retry loop when StreamIdleTimeoutError occurs during tool input generation
• Tasks/Subagents with Codex / OpenAI are frequently getting stuck with no timeout/retry, which then hangs the session forever #11865: Tasks/Subagents with Codex frequently getting stuck with no timeout/retry
• always stuck at “Preparing write...” #11112: Agent stuck at 'Preparing write...' in a tool execution loop
• Loop in certain models #3743: Loop in certain models (explicitly mentions 2-8B models like yours)
• Has anyone been successful at setting up Kimi K2.5 via NanoGPT? #11529: Kimi K2.5 loops over in reasoning with smaller models

Feel free to ignore if none of these address your specific case.

doom_loop — triggered when the same tool call repeats 3 times with identical input

(ref) I don't see any tool calls in your screenshot.

[Heinrich-XIAO]

Yeah. That's what I mean. It makes sense for it to catch non-tool call doom loops.

Oh I see, you are targeting this as a feature request. Ok cool, but please mark the issue as such (e.g. using [FEATURE] tag in the title), the feature works as currently designed and is not a bug.

doom loop in thinking has been especially strange because it will think forever, like longer than the context window usually allows. does opencode just continually send requests in thinking mode?
