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)#

bash

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#

bash

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#

bash

# 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#

bash

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:

json

{
  "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:

bash

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#

bash

tmux kill-session -t "$SESSION" 2>/dev/null
git worktree prune

MyClaw-Specific Notes#

• 模型首选 gpt-5.3-codex，轻量测试用 gpt-4.1-mini
