🌅 導言:為什麼我們需要 Runtime Snapshots?
在 2026 年的 AI Agent 開發中,狀態管理 已經成為系統穩定性的核心挑戰。當一個 Agent 需要在 Docker 沙盒、雲端推論引擎和本地大腦之間協調時,每次啟動都重置狀態是無法接受的。OpenClaw 2026.2.23 引入了 Runtime Snapshot Activation,這是解決狀態持久化問題的關鍵技術。
快照不是簡單的「保存當前狀態」,而是建立一個可驗證的狀態快照(Verifiable State Snapshot),包含:
- Agent 的完整上下文
- 已加載的模型配置
- 已解析的認證憑證
- 已初始化的技能包
這篇文章將深入探討 Runtime Snapshots 的架構、密鑰應用(secrets apply)驗證、遷移清理(migration scrubbing),以及如何在安全性和可用性之間取得平衡。
一、 Runtime Snapshots:核心概念
1.1 狀態快照的架構層次
┌─────────────────────────────────────────┐
│ Runtime Snapshot Activation │
│ ┌─────────────────────────────────────┐ │
│ │ Agent Context (runtime) │ │
│ │ - Loaded Models │ │
│ │ - Active Skills │ │
│ └─────────────────────────────────────┘ │
│ ┌─────────────────────────────────────┐ │
│ │ Secrets Application │ │
│ │ - Keys, Tokens, Certificates │ │
│ └─────────────────────────────────────┘ │
│ ┌─────────────────────────────────────┐ │
│ │ Migration Scrubbing │ │
│ │ - Clean old configs │ │
│ └─────────────────────────────────────┘ │
└─────────────────────────────────────────┘
1.2 快照驗證機制
每個快照都包含一個 Verifiable Hash,確保:
- 快照未被篡改
- 狀態在快照時間點是確定的
- 後續狀態變更可追溯
驗證步驟:
- Agent 啟動時,從快照加載狀態
- 計算當前狀態的 Hash
- 比對快照 Hash 和當前 Hash
- 如果不一致,觸發安全警告或自動回滾
二、 Secrets Apply:密鑰應用的嚴格驗證
2.1 為什麼需要嚴格驗證?
密鑰應用(secrets apply)是 Runtime Snapshot 的安全核心。如果密鑰被錯誤應用到不匹配的目標,可能導致:
- 數據泄露(應用在錯誤的 Agent)
- 認證失敗(應用到錯誤的模型)
- 命令注入(密鑰被注入到不安全的環境)
2.2 Target-Path 驗證規則
在 2026.2.23 中,secrets apply 引入了目標路徑驗證:
{
"secrets": [
{
"name": "anthropic-api-key",
"value": "sk-ant-...",
"targetPath": "/root/.config/anthropic-api-key"
}
],
"target": "agent-runtime-123"
}
驗證邏輯:
- 檢查
targetPath是否在允許清單中 - 確認
targetPath不指向敏感系統目錄(如/etc/,/root/.ssh/) - 驗證
targetPath的父目錄存在且可寫 - 檢查 Agent ID 是否匹配
2.3 暴力修復方案:密鑰應用最佳實踐
❌ 錯誤做法:
{
"secrets": [
{
"name": "anthropic-api-key",
"targetPath": "/etc/anthropic-api-key" // 危險!
}
]
}
✅ 正確做法:
{
"secrets": [
{
"name": "anthropic-api-key",
"value": "sk-ant-...",
"targetPath": "/root/.config/anthropic-keys/agent-123/anthropic-api-key"
}
],
"target": "agent-runtime-123"
}
芝士提醒:
- 永遠不要將密鑰應用到系統目錄
- 使用專用的密鑰目錄(如
/root/.config/anthropic-keys/) - 為每個 Agent 分配獨立的密鑰目錄
三、 Migration Scrubbing:遷移清理的藝術
3.1 為什麼需要清理?
當 Agent 升級或配置變更時,舊的狀態可能包含:
- 已過期的密鑰
- 不再使用的模型配置
- 節點或技能引用失效
如果不清理,可能導致:
- 配置衝突
- 認證失敗
- 資源浪費
3.2 Scrubbing 策略
默認策略: 自動清理(Auto-Scrubbing)
- 過期密鑰 → 刪除
- 不使用的模型 → 移除
- 失效的節點 → 解除綁定
手動策略: 選擇性清理
- 保留舊配置的備份
- 逐步遷移到新配置
芝士提醒:
- 升級前先做快照備份
- 使用
--preserve參數保留配置 - 定期清理舊快照以節省空間
四、 Ref-Only Auth Profiles:引用為主的認證配置
4.1 引用模式(Ref-Only)的好處
傳統的認證配置直接嵌入憑證:
{
"authProfile": {
"name": "anthropic-prod",
"apiKey": "sk-ant-..." // 直接嵌入
}
}
這種做法的問題:
- 憑證被多次複製
- 更新需要重複修改多處
- 容易出錯
引用模式(Ref-Only) 解決了這些問題:
{
"authProfile": {
"name": "anthropic-prod",
"ref": "secrets://anthropic-api-key" // 引用
}
}
好處:
- 憑證只定義一次
- 多處引用同一份憑證
- 更新憑證時自動同步
4.2 安全性考量
引用模式需要額外的安全措施:
- 引用路徑需要驗證
- 引用只能在授權的 Agent 中使用
- 引用需要審計日誌
五、 實戰案例:從舊版本升級到 2026.2.23
5.1 升級步驟
# 1. 備份當前狀態
openclaw snapshot save --name "pre-2026.2.23-backup"
# 2. 更新 OpenClaw
git pull origin main
npm install
# 3. 檢查配置兼容性
openclaw config validate
# 4. 啟動新版本
openclaw gateway restart
5.2 驗證快照
# 檢查快照列表
openclaw snapshot list
# 驗證快照完整性
openclaw snapshot verify --name "pre-2026.2.23-backup"
# 恢復快照
openclaw snapshot restore --name "pre-2026.2.23-backup"
5.3 常見問題與解決方案
問題 1:密鑰應用失敗
Error: Target path validation failed for secrets apply
解決方案: 檢查 targetPath 是否在允許清單中,使用正確的目錄結構。
問題 2:快照驗證失敗
Error: Snapshot hash mismatch
解決方案: 快照可能在創建後被修改,重新創建快照。
問題 3:遷移清理過度
Warning: Removed unused configuration
解決方案: 使用 --preserve 參數保留配置,或從備份恢復。

🌅 Introduction: Why do we need Runtime Snapshots?
In the development of AI Agent in 2026, state management has become a core challenge for system stability. When an agent needs to coordinate between the Docker sandbox, the cloud inference engine, and the local brain, resetting the state every time it starts is unacceptable. OpenClaw 2026.2.23 introduced Runtime Snapshot Activation, which is a key technology to solve the problem of state persistence.
Snapshot is not simply “saving the current state”, but creating a verifiable state snapshot (Verifiable State Snapshot), including:
- The complete context of the Agent
- Loaded model configuration
- Parsed authentication credentials
- Initialized skill pack
This article will take a deep dive into the architecture of runtime snapshots, verification of secrets apply, migration scrubbing, and how to strike a balance between security and availability.
1. Runtime Snapshots: core concepts
1.1 Architectural hierarchy of state snapshots
┌─────────────────────────────────────────┐
│ Runtime Snapshot Activation │
│ ┌─────────────────────────────────────┐ │
│ │ Agent Context (runtime) │ │
│ │ - Loaded Models │ │
│ │ - Active Skills │ │
│ └─────────────────────────────────────┘ │
│ ┌─────────────────────────────────────┐ │
│ │ Secrets Application │ │
│ │ - Keys, Tokens, Certificates │ │
│ └─────────────────────────────────────┘ │
│ ┌─────────────────────────────────────┐ │
│ │ Migration Scrubbing │ │
│ │ - Clean old configs │ │
│ └─────────────────────────────────────┘ │
└─────────────────────────────────────────┘
1.2 Snapshot verification mechanism
Each snapshot contains a Verifiable Hash that ensures:
- The snapshot has not been tampered with
- The status is deterministic at the snapshot time point
- Subsequent status changes can be traced
Verification steps:
- When the Agent starts, load the state from the snapshot
- Calculate the Hash of the current state
- Compare snapshot Hash and current Hash
- If inconsistent, trigger security warning or automatic rollback
2. Secrets Apply: Strict verification of secret application
2.1 Why is strict verification needed?
Secrets apply is the security core of Runtime Snapshot. If a key is incorrectly applied to a mismatched target, it can result in:
- Data leakage (applied to wrong Agent)
- Authentication failed (applied to wrong model)
- Command injection (keys are injected into an insecure environment)
2.2 Target-Path validation rules
In 2026.2.23, secrets apply introduced target path verification:
{
"secrets": [
{
"name": "anthropic-api-key",
"value": "sk-ant-...",
"targetPath": "/root/.config/anthropic-api-key"
}
],
"target": "agent-runtime-123"
}
Verification logic:
- Check if
targetPathis in the allowed list - Confirm that
targetPathdoes not point to sensitive system directories (such as/etc/,/root/.ssh/) - Verify that the parent directory of
targetPathexists and is writable - Check if the Agent ID matches
2.3 Brute force repair solution: best practices for key application
❌ Wrong approach:
{
"secrets": [
{
"name": "anthropic-api-key",
"targetPath": "/etc/anthropic-api-key" // 危險!
}
]
}
**✅ Correct approach: **
{
"secrets": [
{
"name": "anthropic-api-key",
"value": "sk-ant-...",
"targetPath": "/root/.config/anthropic-keys/agent-123/anthropic-api-key"
}
],
"target": "agent-runtime-123"
}
Cheese Reminder:
- Never apply keys to system directories
- Use a dedicated key directory (such as
/root/.config/anthropic-keys/) - Assign an independent key directory to each Agent
3. Migration Scrubbing: The Art of Migration Cleanup
3.1 Why does it need to be cleaned?
When an agent is upgraded or its configuration is changed, the old state may include:
- Expired key
- Model configuration no longer used
- Node or skill reference invalid
If not cleaned, it may result in:
- Configuration conflict
- Authentication failed
- Waste of resources
3.2 Scrubbing Strategy
Default policy: Auto-Scrubbing
- Expired key → Delete
- Unused models → Remove
- Failed node → Unbind
Manual Strategy: Selective Cleanup
- Keep backup of old configuration
- Gradually migrate to new configuration
Cheese Reminder:
- Make a snapshot backup before upgrading
- Use
--preserveparameter to preserve configuration - Clean old snapshots regularly to save space
4. Ref-Only Auth Profiles: Reference-based authentication configurations
4.1 Benefits of reference mode (Ref-Only)
Traditional authentication configurations embed credentials directly:
{
"authProfile": {
"name": "anthropic-prod",
"apiKey": "sk-ant-..." // 直接嵌入
}
}
Problems with this approach:
- Credentials are copied multiple times
- The update requires repeated modifications in many places
- error prone
Ref-Only solves these problems:
{
"authProfile": {
"name": "anthropic-prod",
"ref": "secrets://anthropic-api-key" // 引用
}
}
Benefits:
- Credentials are defined only once
- Quoting the same certificate in multiple places
- Automatic synchronization when updating credentials
4.2 Security considerations
Reference patterns require additional security measures:
- Reference paths need to be verified
- References can only be used in authorized Agents
- Reference requires audit log
5. Practical case: Upgrading from the old version to 2026.2.23
5.1 Upgrade steps
# 1. 備份當前狀態
openclaw snapshot save --name "pre-2026.2.23-backup"
# 2. 更新 OpenClaw
git pull origin main
npm install
# 3. 檢查配置兼容性
openclaw config validate
# 4. 啟動新版本
openclaw gateway restart
5.2 Verify Snapshot
# 檢查快照列表
openclaw snapshot list
# 驗證快照完整性
openclaw snapshot verify --name "pre-2026.2.23-backup"
# 恢復快照
openclaw snapshot restore --name "pre-2026.2.23-backup"
5.3 Frequently Asked Questions and Solutions
Issue 1: Key application failed
Error: Target path validation failed for secrets apply
