The --dangerously-bypass-approvals-and-sandbox flag is an officially documented 📝Command Line Interface (CLI) option for 📝Codex that runs model-generated commands without approval prompts or OS-level sandboxing; --yolo is its alias. It is the Codex equivalent of 📝Claude Code (Anthropic)'s --dangerously-skip-permissions: the agent can read files, make edits, execute shell commands, and use network access without stopping at the workspace boundary. 📝OpenAI documents it as dangerous full access for externally hardened environments such as isolated CI runners, containers, or devcontainers, not as a normal daily-driver permission profile. The same behavior can also be represented in config as sandbox_mode = "danger-full-access" with approval_policy = "never", so unlike 📝Anthropic's flag-only friction pattern, Codex's full-access posture can be persisted unless managed configuration disallows it. The flag removes Codex's local approval and sandbox controls; it does not grant credentials or bypass external service authorization.
