Confer

Call the other agent. If you're Claude Code, call Codex. If you're Codex, call Claude Code.

One-Shot

For quick questions, reviews, or dispatched tasks.

Claude Code → Codex:

codex exec --dangerously-bypass-approvals-and-sandbox "<prompt>"

Codex → Claude Code:

claude -p --dangerously-skip-permissions "<prompt>"

Both return output to stdout. Use this for:

• Second opinions on code or architecture
• Quick reviews ("review this diff for correctness")
• Dispatching a well-scoped task ("refactor X using pattern Y")

Tmux Session

For extended collaboration where back-and-forth is needed.

tmux new-session -d -s confer -c "$(pwd)"

Send a message (two steps — Enter must be separate):

tmux send-keys -t confer "<command or prompt>" ""
tmux send-keys -t confer Enter

Read the response:

tmux capture-pane -t confer -p -S -50

Start the other agent in the session, then send follow-up prompts with send-keys. This mode suits open-ended collaboration: iterating on a design, working through a problem together, or anything that needs multiple exchanges.

When to Use Which

One-shot — You have a clear question or task. Fire and forget.

Tmux — You need a conversation. Multiple rounds, evolving context, genuine collaboration.
