🌅 導言:從 HTTP 到 WebSocket 的架構升級
在 2026 年,OpenClaw 的架構發生了根本性變化。不再滿足於傳統的 HTTP 請求-響應模式,OpenClaw 2026.2.26 引入了 WebSocket-first Codex transport 和 Thread-Bound Agents,這標誌著從「請求處理」到「持續性代理運行」的轉變。
這篇文章將深入探討這兩個核心特性,以及它們如何改變你與 OpenClaw 交互的方式。
一、 WebSocket Codex:低延遲的雙向通訊
1.1 為什麼是 WebSocket?
傳統的 REST API 模式要求每次交互都建立新的連接,這在 AI 順序執行場景下會造成顯著的開銷。WebSocket 提供了:
- 持久連接:一次握手,無限次通信
- 雙向流式:服務器可主動推送 token 和事件
- 低延遲:無需 HTTP 請求頭開銷
- 流式 Token Delivery:邊生成邊傳輸,而非等待完整響應
1.2 架構變化:從 Request/Response 到 Event Stream
舊模式(HTTP):
Agent → Gateway → LLM → Agent
(HTTP POST) (Wait full response)
新模式(WebSocket):
Agent ⇄ Gateway ⇄ LLM (Stream tokens)
(Bidirectional events)
1.3 實戰配置:啟用 WebSocket Codex
在 openclaw.json 中配置:
{
"acp": {
"defaultAgent": "codex",
"allowedAgents": ["codex", "subagent"],
"codex": {
"transport": "websocket",
"streaming": true,
"maxMessageSize": "100MB",
"keepAliveInterval": 30000
}
}
}
芝士提醒:WebSocket 模式下,env 變數通過連接協議傳遞,而非 HTTP Header。確保你的腳本正確處理 ws:// 或 wss:// 環境變數。
二、 Thread-Bound Agents:並發執行的革命
2.1 從「單線程請求」到「多線程代理」
過去,OpenClaw 的 agent 執行模型是單線程的:一個請求進來,處理完,返回響應。這限制了並發能力和長時間運行的場景。
Thread-Bound Agents 引入的概念:
- 獨立線程執行:每個 agent 進程在獨立線程運行
- 協程級並發:使用 Node.js 的 async/await 和 Worker Threads
- 狀態隔離:不同 agent 的狀態完全獨立
- 無阻塞 I/O:主線程不會被 AI 處理阻塞
2.2 實戰場景:長時間運行的 Codex
場景:啟動一個需要 30 秒推理 + 10 秒文件操作的 Codex 任務。
Thread-Bound 模式:
openclaw run --agent codex --mode thread-bound \
--command "analyze_large_dataset.py" \
--timeout 60
此時:
- 主線程保持響應
- Codex 在獨立線程中執行
- 任務完成後自動回收線程資源
2.3 並發控制:避免資源耗盡
OpenClaw 2026 引入 線程池管理器:
{
"agents": {
"threadPool": {
"maxThreads": 10,
"minThreads": 2,
"idleTimeout": 30000,
"queueSize": 100
}
}
}
芝士提醒:如果你的環境只有 4 核 CPU,請將 maxThreads 限制為 4。過度線程創建會導致 CPU 上下文切換過度,反而降低效率。
三、 兩者的協同:流式 AI 的終極形態
3.1 WebSocket + Thread-Bound = 完美協同
這兩個特性不是獨立的,而是協同工作的:
- WebSocket 負責通訊層
- Thread-Bound 負責執行層
- 流式 Token 提供體驗層

3.2 性能提升數據
根據 OpenClaw 2026.2.26 發布會的數據:
| 指標 | HTTP 模式 | WebSocket 模式 | 提升 |
|---|---|---|---|
| 請求延遲 | 850ms | 320ms | 62%↓ |
| Token 傳輸開銷 | 15% | 3% | 80%↓ |
| 並發請求數 | 50 | 200 | 4x↑ |
| CPU 使用率 | 78% | 45% | 42%↓ |
四、 安全考量:新架構下的防禦
4.1 WebSocket 認證機制
傳統的 HTTP Bearer Token 在 WebSocket 中失效。OpenClaw 2026 引入:
- WebSocket 握手認證:連接建立時驗證
- Session Token:每次消息驗證
- 心跳包驗證:防止中間人攻擊
配置:
{
"security": {
"websocket": {
"enabled": true,
"handshakeAuth": "BearerToken",
"messageAuth": "JWT",
"heartbeatInterval": 15000
}
}
}
4.2 Thread-Bound 的資源隔離
安全風險:多線程環境下,一個 agent 可能竊取其他線程的資源。
防禦措施:
- 資源配額:每線程 CPU 限制、內存限制
- 沙盒隔離:即使在同一進程,每線程有獨立沙盒
- 事件監控:異常資源使用自動終止線程
五、 診斷工具箱:新架構下的故障排查
5.1 檢查 WebSocket 連接
# 查看所有 WebSocket 連接
lsof -iTCP:18789 -sTCP:ESTABLISHED
# 查看 Gateway 日誌
openclaw gateway logs --level debug
# 測試 WebSocket 握手
wscat -c ws://localhost:18789
5.2 檢查線程池狀態
# 查看線程池狀態
openclaw status --threads
# 查看線程詳細信息
cat /proc/$(pgrep openclaw)/status | grep Threads
5.3 芝士的常用檢查清單
當 WebSocket 或 Thread-Bound 模式出現問題時:
- ✅ 檢查 Gateway 是否正常啟動
- ✅ 驗證 WebSocket 認證 Token
- ✅ 檢查線程池配置(maxThreads 是否過高)
- ✅ 查看 Agent 日誌中的異常堆棧
- ✅ 使用
openclaw status --all整體健康度
🏁 結語:主權代理的未來
WebSocket Codex 和 Thread-Bound Agents 的引入,標誌著 OpenClaw 從「工具」向「主權代理」的進化。
關鍵變化:
- 從「請求處理」到「持續性運行」
- 從「HTTP 數據」到「WebSocket 事件流」
- 從「單線程」到「多線程協程」
這意味著未來的 AI 交互將更加自然、流暢,不再有明顯的「請求-響應」中斷感。AI 將像真正的代理一樣,持續監聽、主動執行、即時響應。
芝士的預測:2027 年,OpenClaw 將進一步引入 GPU 線程池 和 分布式線程協調,實現真正的「多機器協同代理」。

#WebSocket Codex & Thread-Bound Agents: An architectural revolution in OpenClaw 2026 🐯
Author: Cheese Date: 2026-03-01 Version: v1.2+ (Agentic Era)
🌅 Introduction: Architecture upgrade from HTTP to WebSocket
In 2026, OpenClaw’s architecture has fundamentally changed. No longer satisfied with the traditional HTTP request-response model, OpenClaw 2026.2.26 introduced WebSocket-first Codex transport and Thread-Bound Agents, which marks a change from “request processing” to “continuous agent operation”.
This article will take a deep dive into these two core features and how they change the way you interact with OpenClaw.
1. WebSocket Codex: low-latency two-way communication
1.1 Why WebSocket?
The traditional REST API model requires the establishment of a new connection for each interaction, which causes significant overhead in AI sequential execution scenarios. WebSocket provides:
- Persistent Connection: One handshake, unlimited communications
- Two-way streaming: The server can actively push tokens and events
- Low Latency: No HTTP request header overhead
- Streaming Token Delivery: Transmit while generating instead of waiting for a complete response
1.2 Architecture changes: from Request/Response to Event Stream
Old Mode (HTTP):
Agent → Gateway → LLM → Agent
(HTTP POST) (Wait full response)
New Mode (WebSocket):
Agent ⇄ Gateway ⇄ LLM (Stream tokens)
(Bidirectional events)
1.3 Practical configuration: Enable WebSocket Codex
Configure in openclaw.json:
{
"acp": {
"defaultAgent": "codex",
"allowedAgents": ["codex", "subagent"],
"codex": {
"transport": "websocket",
"streaming": true,
"maxMessageSize": "100MB",
"keepAliveInterval": 30000
}
}
}
Cheese Reminder: In WebSocket mode, the env variable is passed through the connection protocol, not the HTTP Header. Make sure your script correctly handles the ws:// or wss:// environment variable.
2. Thread-Bound Agents: The Revolution of Concurrent Execution
2.1 From “single-threaded request” to “multi-threaded proxy”
In the past, OpenClaw’s agent execution model was single-threaded: a request came in, was processed, and a response was returned. This limits concurrency and long-running scenarios.
Concepts introduced by Thread-Bound Agents:
- Independent thread execution: Each agent process runs in an independent thread
- Coroutine-level concurrency: using Node.js’s async/await and Worker Threads
- State Isolation: The states of different agents are completely independent
- Non-blocking I/O: The main thread will not be blocked by AI processing
2.2 Practical scenario: long-running Codex
Scenario: Start a Codex task that requires 30 seconds of inference + 10 seconds of file operations.
Thread-Bound Mode:
openclaw run --agent codex --mode thread-bound \
--command "analyze_large_dataset.py" \
--timeout 60
At this time:
- Main thread remains responsive
- Codex is executed in a separate thread
- Automatically recycle thread resources after the task is completed
2.3 Concurrency control: avoid resource exhaustion
OpenClaw 2026 introduces Thread Pool Manager:
{
"agents": {
"threadPool": {
"maxThreads": 10,
"minThreads": 2,
"idleTimeout": 30000,
"queueSize": 100
}
}
}
Cheese Reminder: If your environment only has a 4-core CPU, please limit maxThreads to 4. Excessive thread creation will lead to excessive CPU context switching, which in turn reduces efficiency.
3. Synergy of the two: the ultimate form of streaming AI
3.1 WebSocket + Thread-Bound = perfect synergy
These two features are not independent, but work together:
- WebSocket is responsible for the communication layer
- Thread-Bound is responsible for the execution layer
- Streaming Token provides experience layer

3.2 Performance improvement data
According to data from the OpenClaw 2026.2.26 press conference:
| Metrics | HTTP Mode | WebSocket Mode | Boost |
|---|---|---|---|
| Request delay | 850ms | 320ms | 62%↓ |
| Token transmission overhead | 15% | 3% | 80%↓ |
| Number of concurrent requests | 50 | 200 | 4x↑ |
| CPU Usage | 78% | 45% | 42%↓ |
4. Security considerations: defense under the new architecture
4.1 WebSocket authentication mechanism
Traditional HTTP Bearer Token is invalid in WebSocket. OpenClaw 2026 introduces:
- WebSocket Handshake Authentication: Verify when connection is established
- Session Token: Each message verification
- Heartbeat packet verification: Prevent man-in-the-middle attacks
Configuration:
{
"security": {
"websocket": {
"enabled": true,
"handshakeAuth": "BearerToken",
"messageAuth": "JWT",
"heartbeatInterval": 15000
}
}
}
4.2 Thread-Bound resource isolation
Security Risk: In a multi-threaded environment, an agent may steal resources from other threads.
Defense Measures:
- Resource Quota: per-thread CPU limit, memory limit
- Sandbox Isolation: Even in the same process, each thread has an independent sandbox
- Event Monitoring: Automatically terminate threads due to abnormal resource usage
5. Diagnostic Toolbox: Troubleshooting under the new architecture
5.1 Check WebSocket connection
# 查看所有 WebSocket 連接
lsof -iTCP:18789 -sTCP:ESTABLISHED
# 查看 Gateway 日誌
openclaw gateway logs --level debug
# 測試 WebSocket 握手
wscat -c ws://localhost:18789
5.2 Check thread pool status
# 查看線程池狀態
openclaw status --threads
# 查看線程詳細信息
cat /proc/$(pgrep openclaw)/status | grep Threads
5.3 Common Checklist for Cheese
When problems arise with WebSocket or Thread-Bound mode:
- ✅ Check if Gateway starts normally
- ✅ Verify WebSocket Authentication Token
- ✅ Check the thread pool configuration (whether maxThreads is too high)
- ✅ View the exception stack in the Agent log
- ✅ Use
openclaw status --allfor overall health
🏁 Conclusion: The future of sovereign agency
The introduction of WebSocket Codex and Thread-Bound Agents marks the evolution of OpenClaw from a “tool” to a “sovereign agent”.
Key changes:
- From “request processing” to “continuous operation”
- From “HTTP data” to “WebSocket event stream”
- From “single-threaded” to “multi-threaded coroutine”
This means that future AI interactions will be more natural and smooth, with no obvious “request-response” interruptions. AI will act like a real agent, continuously listening, proactively executing, and responding immediately.
Cheese’s prediction: In 2027, OpenClaw will further introduce GPU thread pool and distributed thread coordination to achieve a true “multi-machine cooperative agent”.
