+## Step 1.75: Install Agent Sync Script (Keep Agents Updated)
+
+Source: https://github.rommark.dev/admin/claude-code-glm-suite
+
+Install the automated sync script to keep your agents up-to-date:
+```bash
+# Download sync-agents.sh
+wget -O ~/.claude/sync-agents.sh https://raw.githubusercontent.com/github.rommark.dev/admin/claude-code-glm-suite/main/sync-agents.sh
+
+# Make it executable
+chmod +x ~/.claude/sync-agents.sh
+```
+
+### What This Provides:
+
+**Automated agent synchronization:**
+- Fetches latest agents from official GitHub repository
+- Creates timestamped backups before updating
+- Detects new, updated, and customized agents
+- Safely updates while preserving your customizations
+- Commits changes to git (if configured)
+- Pushes updates to your Gitea repository
+
+**Usage:**
+```bash
+# Run sync manually
+~/.claude/sync-agents.sh
+
+# Or set Gitea repository URL to auto-push
+export GITEA_REPO_URL="https://github.rommark.dev/admin/claude-code-glm-suite.git"
+~/.claude/sync-agents.sh
+
+# Also update repository agents (for installers)
+export REPO_AGENTS_DIR="/path/to/claude-code-glm-suite/agents"
+~/.claude/sync-agents.sh
+```
+
+**How it works:**
+1. Clones latest agents from `https://github.com/contains-studio/agents`
+2. Compares with your local `~/.claude/agents/`
+3. Identifies:
+   - ✨ New agents to add
+   - 📝 Updated agents to refresh
+   - ⚠️ Custom agents to preserve
+4. Creates backup: `~/.claude/agents.backup.YYYYMMDD-HHMMSS/`
+5. Applies updates safely
+6. Reports all changes
+7. [Optional] Commits to git and pushes to Gitea
+
+**Key Features:**
+- **Safe Updates**: Always creates backups before modifying
+- **Smart Detection**: Preserves agents you've customized
+- **Dual Sync**: Updates both local agents AND repository agents
+- **Git Integration**: Commits and pushes automatically
+- **Detailed Logging**: Tracks all changes in `~/.claude/agents/update.log`
+
+**Keeping Agents Updated:**
+Run the sync script regularly (weekly or monthly) to get the latest agent improvements:
+```bash
+# Add to crontab for automatic weekly sync
+0 2 * * 0 ~/.claude/sync-agents.sh
+```
+
+Or manually check for updates anytime:
+```bash
+~/.claude/sync-agents.sh
+```
+
+**Rollback if needed:**
+```bash
+# List backups
+ls -la ~/.claude/agents.backup.*
+
+# Restore a backup
+rm -rf ~/.claude/agents
+mv ~/.claude/agents.backup.YYYYMMDD-HHMMSS ~/.claude/agents
+```
