Read the exit code. 42 is bad input and 53 is the turn limit\n5. Use `--output-format stream-json` to get tool calls and results as JSONL events\n\n### OpenAI Codex\n\n1. Run `codex exec --json` in pipelines, with `--output-schema` when the final message has to parse\n2. Keep the default sandbox. `--yolo` removes both the sandbox and approvals\n3. Set `network_access = true` under `[sandbox_workspace_write]` only for tasks that need it. Network is off by default\n4.
