Collaborating With Codex

Quick Start

python scripts/codex_bridge.py --cd "/path/to/project" --PROMPT "Your task"

Remote Codex over SSH:

python scripts/codex_bridge.py --ssh "server-alias" --cd "/remote/project" --PROMPT "Your task"

Output: JSON with success, SESSION_ID, agent_messages, and optional error.

Collaboration Rules

• Keep the current session responsible for scope, synthesis, final edits, and verification.
• Delegate a bounded task with a concrete output contract such as a diff, diagnosis, or review note.
• Avoid overlapping write scope between sessions unless the second session is review-only.
• Start with read-only access; expand the sandbox only when the delegated task requires it.
• Do not set model or profile overrides unless the user explicitly asked for them.

Parameters

usage: codex_bridge.py [-h] --PROMPT PROMPT --cd CD [--sandbox {read-only,workspace-write,danger-full-access}] [--SESSION_ID SESSION_ID] [--skip-git-repo-check]

                       [--codex-bin CODEX_BIN]

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.
  --ssh SSH             Run Codex on a remote host via SSH. Value can be an SSH alias or user@host. When set, --cd and --image paths are remote paths.
  --ssh-option SSH_OPTION
                        Extra ssh option, repeatable. Example: --ssh-option=-J --ssh-option=bastion
  --codex-bin CODEX_BIN
                        Codex executable to run locally or on the remote host. Defaults to `codex`. `--remote-codex` is accepted as a backward-compatible alias.

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"

Remote sessions use the same SESSION_ID, but continue them against the same SSH host:

python scripts/codex_bridge.py --ssh "server-alias" --cd "/remote/project" --SESSION_ID "uuid-from-response" --PROMPT "Now implement it"

SSH Remote Codex

Use --ssh when the repository, runtime, or credentials needed for the task live on a remote server.

Requirements:

• Local machine can run ssh <host> non-interactively.
• Remote host has codex installed and available in the remote non-interactive shell PATH, or pass --codex-bin "/absolute/path/to/codex".
• The remote host should use a POSIX-compatible shell for command quoting.
• --cd is a remote absolute path when --ssh is set.
• --image paths are also remote paths when --ssh is set. Upload local images first if Codex on the server needs them.

Examples:

# Use an SSH config alias
python scripts/codex_bridge.py --ssh "gpu-box" --cd "/srv/app" --PROMPT "Review this service for race conditions"

# Use user@host and a remote codex path
python scripts/codex_bridge.py --ssh "ubuntu@example.com" --codex-bin "/home/ubuntu/.local/bin/codex" --cd "/home/ubuntu/app" --PROMPT "Run the failing tests and diagnose"

# Use a jump host
python scripts/codex_bridge.py --ssh "private-box" --ssh-option=-J --ssh-option=bastion --cd "/workspace/repo" --PROMPT "Inspect the deployment scripts"

Do not use --ssh for local repositories. Do not pass --model or --profile unless the user explicitly requested them.

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

Remote debug with write access:

python scripts/codex_bridge.py --ssh "server-alias" --cd "/remote/project" --sandbox workspace-write --PROMPT "Fix the failing integration test and summarize the patch"
