I had QWen 3.8 27B refactor some fairly complex shell script https://github.com/ag88/llama.cpp-model-runner The task is to add a --rundefault option so that runmodel.sh would run llama.cpp's llama-server with a default model and configs. I had it worked through an MCP server cmdshellmcp and Docker sandbox and actually edit codes. Some of the edits worked, but that among them some edits failed due to newline handling. It did the plan and edits fairly well catching some fine details as the global variables are passed to llama-server from json configs and synthetic variables which are not intended for llama-server needs to be filtered out, it catch that without the requirement in the prompt. I prompted the model that I'm making the edits manually, I set a context length of 65535 and I think I'm quickly running out of context budget in a lengthy session with rather verbose codes. And I had it explain the edits and validate my manual edits, the session literally feels "sentinent" prompt: read the file "runmodel.sh.diff" this is the unified diff with the latest updates vs the original backup, verify if the edits are correct and complete QWen 3.8 27B response: I've read runmodel.sh.diff and verified it against the required changes. ✅ The edits are correct and complete. Here's the verification, hunk by hunk: 1. run_model() — extra-globals jq filter (line 134 hunk) diff - done <   submitted by
