The Problem

Your OpenClaw conversations live in session files. When things go wrong — and they will — you lose everything:

• 🔴 Gateway restart → entire conversation history gone
• 🔴 Model disconnection → mid-task context wiped out
• 🔴 Token overflow → session too large, agent slows down or crashes
• 🔴 Disk issues → session files corrupted or lost

No built-in backup. No recovery. No warning before it's too late.

The Fix

clawhub install session-guardian
bash ~/.openclaw/workspace/skills/session-guardian/scripts/install.sh

That's it. Five layers of protection, running automatically.

How It Works

Layer 1: Incremental Backup    → Every 5 min   → New conversations saved
Layer 2: Hourly Snapshot       → Every hour     → Full session snapshots
Layer 3: Health Check          → Every 6 hours  → Detect problems early
Layer 4: Smart Summary         → Daily          → Key info extracted
Layer 5: Knowledge Extraction  → Daily          → Best practices saved

All automatic. All in the background. Zero manual work.

Quick Start

# Install
clawhub install session-guardian

# Deploy (sets up all cron jobs automatically)
cd ~/.openclaw/workspace/skills/session-guardian
bash scripts/install.sh

# Check status
bash scripts/status.sh

What You Get

• ✅ Auto-backup every 5 minutes — never lose more than 5 min of conversation
• ✅ Hourly snapshots — full point-in-time recovery
• ✅ Health monitoring — warns before token overflow crashes your agent
• ✅ One-command recovery — restore any session from any backup
• ✅ Multi-agent support — protects all your agents, not just main
• ✅ Collaboration tracking — see task flow across agents (King → Lead → Members)
• ✅ Knowledge extraction — auto-saves best practices from conversations
• ✅ Minimal overhead — ~10-15k tokens/day, ~1-2MB/agent/month

Usage

Check Status

bash ~/.openclaw/workspace/skills/session-guardian/scripts/status.sh

Shows: backup count, last backup time, snapshot count, cron jobs, disk usage.

Run Health Check

bash ~/.openclaw/workspace/skills/session-guardian/scripts/health-check.sh

Detects: oversized sessions, missing configs, disk space issues, gateway problems.

Restore a Session

# List available backups
bash ~/.openclaw/workspace/skills/session-guardian/scripts/restore.sh list

# Restore specific agent
bash ~/.openclaw/workspace/skills/session-guardian/scripts/restore.sh restore --agent main

View Collaboration Health (Multi-Agent)

bash ~/.openclaw/workspace/skills/session-guardian/scripts/collaboration-health.sh report

Track Task Flow

bash ~/.openclaw/workspace/skills/session-guardian/scripts/collaboration-tracker.sh trace "task name"

Cron Jobs (Auto-Configured)

After install.sh, these run automatically:

| Schedule | Task | What it does | |----------|------|-------------| | Every 5 min | Incremental backup | Save new conversations | | Every hour | Snapshot | Full session archive | | Every 6 hours | Health check | Detect problems | | Daily 2am | Smart summary | Extract key info |

File Structure

Assets/SessionBackups/
├── incremental/     # Every-5-min backups
├── hourly/          # Hourly snapshots
├── collaboration/   # Task flow records
└── Knowledge/       # Extracted best practices

All backups stay local. Nothing leaves your machine.

Who Is This For

Solo Agent User

✅ Protect your main conversation from crashes ✅ Get warned before token overflow kills your agent ✅ Recover in seconds, not hours of re-explaining

Multi-Agent Team

✅ Protect all agents (King + team leads + members) ✅ Track collaboration: who assigned what, who finished what ✅ Health scoring: monitor team communication quality ✅ Knowledge extraction: auto-save best practices from every agent

Troubleshooting

| Problem | Fix | |---------|-----| | Backups not running | Check crontab -l \| grep session-guardian | | Agent slow/timing out | Run health-check — likely token overflow | | Can't restore | Run restore.sh list to see available backups | | Disk filling up | Check config retention settings (default: 7 days incremental, 30 days snapshots) |

Configuration

Edit scripts/config.sh to customize:

BACKUP_DIR         # Where backups go (default: Assets/SessionBackups)
INCREMENTAL_KEEP   # Days to keep incremental backups (default: 7)
SNAPSHOT_KEEP      # Days to keep snapshots (default: 30)
MAX_SESSION_SIZE   # Alert threshold for session size (default: 5MB)

Security

• All data stays local — no external services, no network requests
• No API keys required
• Backups are excluded from git (add to .gitignore)
• Does not modify your session files — only reads and copies

Performance

| Operation | Tokens | Storage | |-----------|--------|---------| | Incremental backup | ~100/run | ~10KB/session/day | | Hourly snapshot | ~500/run | ~100KB/session/day | | Health check | ~200/run | ~2KB/report | | Daily summary | ~5k/run | ~5KB/day | | Total | ~10-15k/day | ~1-2MB/agent/month |

Session Guardian 🛡️ — 再也不丢对话

你的 OpenClaw 对话存在 session 文件里。Gateway 一重启、模型一断连、token 一溢出——对话就没了。没有备份，没有恢复，没有预警。

痛点

• 🔴 Gateway 重启 → 整个对话历史消失
• 🔴 模型断连 → 做到一半的任务上下文全丢
• 🔴 Token 溢出 → session 太大，Agent 变慢甚至崩溃
• 🔴 磁盘问题 → session 文件损坏或丢失

解决方案

clawhub install session-guardian
bash ~/.openclaw/workspace/skills/session-guardian/scripts/install.sh

五层自动防护，后台运行，零手动操作。

五层防护

| 层级 | 频率 | 作用 | |------|------|------| | 增量备份 | 每 5 分钟 | 保存新对话，最多丢 5 分钟 | | 快照备份 | 每小时 | 完整 session 存档，支持回滚 | | 健康检查 | 每 6 小时 | 提前发现问题（token 溢出、磁盘不足） | | 智能总结 | 每天 | 提取关键信息到 MEMORY.md | | 知识沉淀 | 每天 | 自动保存最佳实践 |

你会得到

• ✅ 自动备份 — 每 5 分钟一次，最多丢 5 分钟对话
• ✅ 一键恢复 — 从任意备份点恢复 session
• ✅ 健康监控 — 在 token 溢出前预警
• ✅ 多 Agent 支持 — 保护所有 Agent，不只是 main
• ✅ 协作追踪 — 可视化任务流转（King → 团长 → 成员）
• ✅ 知识沉淀 — 自动从对话中提取最佳实践
• ✅ 极低开销 — 每天约 10-15k tokens，每月约 1-2MB/Agent

常用命令

# 查看状态
bash scripts/status.sh

# 健康检查
bash scripts/health-check.sh

# 恢复 session
bash scripts/restore.sh list
bash scripts/restore.sh restore --agent main

# 协作健康度（多 Agent）
bash scripts/collaboration-health.sh report

适用场景

个人用户：保护主对话不丢失，token 溢出前预警，秒级恢复

多 Agent 团队：保护所有 Agent，追踪协作链路，自动沉淀知识

安全性
