Codex Bridge

options:
  -h, --help            show this help message and exit
  --PROMPT PROMPT       Instruction for the task to send to codex.
  --cd CD               Set the workspace root for codex before executing the task.
  --sandbox {read-only,workspace-write,danger-full-access}
                        Sandbox policy for model-generated commands. Defaults to `read-only`.
  --SESSION_ID SESSION_ID
                        Resume the specified session of the codex. Defaults to `None`, start a new session.
  --skip-git-repo-check
                        Allow codex running outside a Git repository (useful for one-off directories).
  --return-all-messages
                        Return all messages (e.g. reasoning, tool calls, etc.) from the codex session. Set to `False` by default, only the agent's final reply message is
                        returned.
  --image IMAGE         Attach one or more image files to the initial prompt. Separate multiple paths with commas or repeat the flag.
  --model MODEL         The model to use for the codex session. This parameter is strictly prohibited unless explicitly specified by the user.
  --yolo                Run every command without approvals or sandboxing. Only use when `sandbox` couldn't be applied.
  --profile PROFILE     Configuration profile name to load from `~/.codex/config.toml`. This parameter is strictly prohibited unless explicitly specified by the user.

Multi-turn Sessions

Always capture SESSION_ID from the first response for follow-up:

# Initial task
python scripts/codex_bridge.py --cd "/project" --PROMPT "Analyze auth in login.py"

# Continue with SESSION_ID
python scripts/codex_bridge.py --cd "/project" --SESSION_ID "uuid-from-response" --PROMPT "Write unit tests for that"

Common Patterns

Prototyping (read-only, request diffs):

python scripts/codex_bridge.py --cd "/project" --PROMPT "Generate unified diff to add logging"

Debug with full trace:

python scripts/codex_bridge.py --cd "/project" --PROMPT "Debug this error" --return-all-messages
