Codex via tmux (WSL2 / Custom Proxy)
Preferred pattern for all Codex full-auto tasks on this machine. Avoids SIGTERM, supports mid-run steering.
Environment (this machine)
OPENAI_API_KEY="sk-5Ds6eFbTEE1zu5fQ14F4FfB5892b419dB1BfC7292147B9Ef"
OPENAI_BASE_URL="http://152.53.52.170:3003/v1"
Always pass both vars. Do NOT rely on shell inheritance — OpenClaw subprocesses don't source .bashrc.
Standard Launch Pattern
SESSION="codex-<feature>" # e.g. codex-auth, codex-tools
WORKDIR=~/MyClaw # or target repo
tmux new-session -d -s "$SESSION" -c "$WORKDIR" \
"OPENAI_API_KEY='sk-5Ds6e...' OPENAI_BASE_URL='http://152.53.52.170:3003/v1' \
codex --model gpt-5.3-codex --full-auto '$(cat /tmp/task.txt)'"
Write long prompts to /tmp/task.txt first, then reference via $(cat /tmp/task.txt).
Monitoring
# Check if alive
tmux has-session -t "$SESSION" 2>/dev/null && echo running || echo done
# Tail output (last 50 lines)
tmux capture-pane -t "$SESSION" -p | tail -50
# Or via OpenClaw exec:
exec("tmux capture-pane -t codex-auth -p | tail -30")
Mid-run Steering
tmux send-keys -t "$SESSION" "停一下。先做 API 层，不要改 UI。" Enter
tmux send-keys -t "$SESSION" "类型定义在 src/types.ts，用那个。" Enter
Task JSON Tracking
Write to /tmp/codex-tasks.json to track parallel jobs:
{
"id": "feat-tools",
"session": "codex-tools",
"model": "gpt-5.3-codex",
"desc": "实现工具系统 exec/read/write/web_fetch",
"repo": "MyClaw",
"startedAt": 1772433000000,
"status": "running"
}
Completion Check
Poll every 2–3 min via:
tmux has-session -t "$SESSION" 2>/dev/null || echo "DONE"
git -C "$WORKDIR" log --oneline -3
Codex "完成" = tmux session 自动退出 + git commit 存在。
Cleanup
tmux kill-session -t "$SESSION" 2>/dev/null
git worktree prune
MyClaw-Specific Notes
- Repo:
~/MyClaw, GitHub: https://github.com/InuyashaYang/MyClaw - 模型首选
