# Codex Exec Autonomous task execution via the codex CLI. Runs non-interactively. Progress streams to stderr; final result on stdout. ```bash codex exec --skip-git-repo-check "task description" < /dev/null ``` For large context, pipe it via stdin. The prompt stays as the argument, context is passed as `<stdin>` automatically: ```bash cat context.txt | codex exec --skip-git-repo-check "question about the context" ``` Route text you did not author through this channel whatever its size — a diff, file contents, a code comment, a plan or spec, third-party feedback, command output. Write the context file with the Write tool so nothing is interpreted on the way in. Keep backticks, `$`, and straight double quotes out of the quoted argument even in text you wrote: the first two stay live inside it, and a double quote ends it. When the prompt itself must carry any of them, as when it quotes a title or a passage, write the whole prompt and its context to one file with the Write tool and pass `-`, so stdin is the entire prompt: ```bash cat prompt.txt | codex exec --skip-git-repo-check - ``` ## Sandbox **All `codex` Bash calls require `dangerouslyDisableSandbox: true`** (network access to OpenAI API). Without it, codex crashes with an `Operation not permitted` panic from the `system-configuration` crate before the model runs. ## Git Repository Check **Every `codex exec` invocation requires `--skip-git-repo-check`**, resume turns included. Outside a git repository codex aborts b...
