#1648 Fail to use strata on opencode due to long prompt.

说明

I can use smoothly in the web page of strataA(details are in the picture) . However, after connecting to opencode, due to opencode's own **_build_** and **_plan_** model, which has its own long prompt, the log of strata shows **the engine stopped unexpectedly after 60 seconds ...** and restart itself,  cannot work in opencode. what's the problem?
