README (SKILL.md)
OpenClaw Updater
Automatically check for and install OpenClaw updates with backup and rollback support.
Overview
This skill provides automated OpenClaw update capabilities:
- Check current vs latest version
- Perform safe updates with automatic backups
- Schedule periodic auto-updates via cron
- Dry-run mode to preview updates
Quick Start
Check Current Version
openclaw --version
Check for Updates (Dry Run)
bash ~/.openclaw/workspace/skills/openclaw-updater/scripts/update-openclaw.sh --dry-run
Perform Update
bash ~/.openclaw/workspace/skills/openclaw-updater/scripts/update-openclaw.sh
Force Reinstall
bash ~/.openclaw/workspace/skills/openclaw-updater/scripts/update-openclaw.sh --force
Setting Up Auto-Updates
Daily Auto-Update via Cron
Add to crontab for daily update checks at 3 AM:
0 3 * * * /bin/bash ~/.openclaw/workspace/skills/openclaw-updater/scripts/update-openclaw.sh >> ~/.openclaw/logs/cron-update.log 2>&1
Or use OpenClaw's built-in cron:
{
"name": "openclaw-auto-update",
"schedule": { "kind": "cron", "expr": "0 3 * * *" },
"payload": {
"kind": "systemEvent",
"text": "Run OpenClaw auto-updater: bash ~/.openclaw/workspace/skills/openclaw-updater/scripts/update-openclaw.sh"
},
"sessionTarget": "main"
}
How It Works
- Version Check: Compares installed version against npm registry
- Backup: Creates timestamped backup of config and workspace
- Update: Runs
npm install -g @openclaw/core@latest - Verify: Confirms new version is installed
- Cleanup: Maintains only last 5 backups
Logs and Backups
- Logs:
~/.openclaw/logs/auto-update.log - Backups:
~/.openclaw/backups/openclaw-backup-YYYYMMDD-HHMMSS.tar.gz
Troubleshooting
Node.js Version Issues
OpenClaw requires Node.js >= 22.16.0. If you see version warnings:
# Check current Node version
node --version
# Update Node.js (using n or nvm)
n install 22.16.0
# or
nvm install 22.16.0 && nvm use 22.16.0
Update Fails
- Check logs:
cat ~/.openclaw/logs/auto-update.log - Verify npm permissions:
npm config get prefix - Try with sudo if needed:
sudo npm install -g @openclaw/core@latest
Rollback
If update causes issues, restore from backup:
cd ~
tar -xzf ~/.openclaw/backups/openclaw-backup-YYYYMMDD-HHMMSS.tar.gz

Usage Guidance
This updater appears to do what it claims, but check these points before installing or scheduling it: 1) The script runs npm install -g which modifies global packages and may require sudo — be comfortable granting that or run tests in a sandbox. 2) Verify the npm package names (@openclaw/core or openclaw) on the npm registry and confirm the package publisher is trusted. 3) Ensure you have Node.js >=22.16.0 and that npm/node/tar are available (the metadata did not list these required binaries). 4) Use --dry-run first and inspect the created backups in ~/.openclaw/backups before relying on automated cron runs. 5) Because the skill source/homepage is unknown, consider reviewing the script locally (it is included) and, if you automate it, restrict cron to run under an account with appropriate permissions and monitor ~/.openclaw/logs/auto-update.log.
Capability Analysis
Type: OpenClaw Skill
Name: linz-openclaw-updater
Version: 1.0.0
The skill is a legitimate utility for updating the OpenClaw tool. It includes a shell script (scripts/update-openclaw.sh) that checks the current version against the npm registry, creates local backups of configuration files, and performs updates using standard npm commands. No evidence of data exfiltration, malicious persistence, or prompt injection was found.
Capability Assessment
Purpose & Capability
The name/description claim an updater for OpenClaw and the SKILL.md plus the included script implement that behavior (version check via npm, backup, install, verification, rollback). One minor inconsistency: registry metadata lists no required binaries, but the script expects node, npm, tar (and possibly notify); these should have been declared.
Instruction Scope
The SKILL.md instructs the agent to run the included script and to optionally schedule it via cron; the script's actions (reading/writing under $HOME/.openclaw, creating backups, querying npm, running npm install -g) are in-scope for an updater. The instructions do not read unrelated system files or exfiltrate data to unexpected endpoints.
Install Mechanism
This is an instruction-only skill with an included shell script (no installer). The script uses npm to fetch packages from the npm registry, which is expected for a Node-based updater. No arbitrary external download URLs or archive extraction from unknown hosts are used.
Credentials
The skill requests no secrets or credentials. It uses only standard environment values (HOME) and an optional OPENCLAW_UPDATE_LOG override; that is proportionate to its purpose.
Persistence & Privilege
always is false and the skill does not request permanent elevated privileges. It suggests adding a cron job (user-controlled) and does not modify other skills or global agent settings.
How to Use
