Skills Updater - 技能自动升级器

自动检测、备份和升级 OpenClaw 技能，支持智能缓存、重试机制、预演模式和详细报告。

Automatically detect, update, and manage OpenClaw skills with intelligent caching, backup, and reporting.

Features

✅ Auto-detection — Scans all installed skills and detects available updates ✅ Smart caching — 24h TTL cache reduces unnecessary API calls ✅ Automatic backup — Creates dated backups before each update ✅ Dry-run mode — Preview changes without modifying anything ✅ Detailed reporting — Generates upgrade summaries to workspace/memory ✅ Retry logic — Exponential backoff handles rate limits gracefully ✅ Security hardened — No hardcoded secrets, proper SSL, secure permissions

Installation

clawhub install skills-updater

Usage

Check for updates (no API calls, uses cache)

python3 ~/.openclaw/skills/skills-updater/scripts/check-skill-updates.py --cache-only

Preview updates without making changes

python3 ~/.openclaw/skills/skills-updater/scripts/check-skill-updates.py --dry-run

Auto-upgrade all skills

python3 ~/.openclaw/skills/skills-updater/scripts/check-skill-updates.py --auto

Verbose output

python3 ~/.openclaw/skills/skills-updater/scripts/check-skill-updates.py --auto -v

How It Works

1. Scan Phase — Walks through all skill directories and reads version info
2. Cache Check — Looks up latest version from cached data (24h old or newer)
3. Detection — Identifies skills where current < latest
4. Backup — Creates timestamped folder copy of each skill before update
5. Update — Downloads and applies latest version from ClawHub
6. Report — Writes summary to ~/.openclaw/workspace/memory/skill-upgrades-YYYY-MM-DD.md

Safety

• Backups always created before real updates (dry-run doesn't backup)
• Cache permissions set to 700 (owner-only read/write)
• SSL verification enabled with proper context handling
• No sensitive data stored or logged
• Rollback ready — all backups preserved on Desktop

API Reference

Command-line Options

Exit Codes

• 0 — Success (updates found or completed)
• 1 — Error (API/filesystem failure)
• 2 — No updates available

Backup & Recovery

Updates create backups at:

~/Desktop/skill-backups/
├── skill-name-1.0.0-20260325-094830/
├── skill-name-1.0.0-20260325-120000/
└── ...

To restore:

cp -r ~/Desktop/skill-backups/skill-name-VERSION-TIMESTAMP ~/.openclaw/skills/skill-name

Configuration

Edit top of script to customize:

SKILLS_DIRS = [...]          # Where to look for skills
BACKUP_DIR = ...             # Backup location
CACHE_TTL_HOURS = 24         # Cache validity period
MAX_RETRIES = 3              # Retry attempts for API
RETRY_DELAY_BASE = 2         # Base retry delay (seconds)

Performance

Tested performance metrics:

• Bulk scan (100 skills): 9,760 skills/sec
• Cache write (100 skills): 3,494 writes/sec
• Cache read (100 skills): 6,775 reads/sec
• Cache-only mode: 0 API calls

Troubleshooting

"Connection timeout"

• Check internet / proxy settings
• Use --cache-only to work offline

"Permission denied on backup"

• Ensure write access to ~/Desktop/skill-backups/
• Check disk space

"Update failed but backup succeeded"

• Backup is preserved at ~/Desktop/skill-backups/
• Manual restore: cp -r the backup folder
