  Usage
    $ codex [options] <prompt>

  Options
    -h, --help                 Show usage and exit
    -m, --model <model>        Model to use for completions (default: o4-mini)
    -i, --image <path>         Path(s) to image files to include as input
    -v, --view <rollout>       Inspect a previously saved rollout instead of starting a session
    -q, --quiet                Non-interactive mode that only prints the assistant's final output
    -a, --approval-mode <mode> Override the approval policy: 'suggest', 'auto-edit', or 'full-auto'

    --auto-edit                Automatically approve file edits; still prompt for commands
    --full-auto                Automatically approve edits and commands when executed in the sandbox

    --no-project-doc           Do not automatically include the repository's 'codex.md'
    --project-doc <file>       Include an additional markdown file at <file> as context
    --full-stdout              Do not truncate stdout/stderr from command outputs

  Dangerous options
    --dangerously-auto-approve-everything
                               Skip all confirmation prompts and execute commands without
                               sandboxing. Intended solely for ephemeral local testing.

  Experimental options
    -f, --full-context         Launch in "full-context" mode which loads the entire repository
                               into context and applies a batch of edits in one go. Incompatible
                               with all other flags, except for --model.

  Examples

    $ codex -q "fix build issues"
