+# Multi-Node Git Sync Skill
+
+This skill provides expertise in synchronizing git changes across AITBC multi-node deployment (genesis, follower, gitea-runner).
+
+## Node Architecture
+
+- **Genesis Node** (localhost): `/opt/aitbc` - Primary development node
+- **Follower Node** (aitbc1): `/opt/aitbc` - Secondary blockchain node
+- **Gitea-Runner Node** (gitea-runner): `/opt/aitbc` - CI/CD runner node
+
+## Git Remote Strategy
+
+- **Primary Remote**: `origin` (Gitea) - Daily development operations
+- **Secondary Remote**: `github` - Milestone releases only
+
+## Common Operations
+
+### Check Multi-Node Git Status
+```bash
+# Check all three nodes
+cd /opt/aitbc
+echo "=== Genesis ===" && git status --short && git rev-parse --short HEAD
+echo "=== Follower ===" && ssh aitbc1 'cd /opt/aitbc && git status --short && git rev-parse --short HEAD'
+echo "=== Gitea-Runner ===" && ssh gitea-runner 'cd /opt/aitbc && git status --short && git rev-parse --short HEAD'
+```
+
+### Sync All Nodes from Genesis
+```bash
+# 1. Commit and push from genesis
+cd /opt/aitbc
+git add . && git commit -m "feat: description" && git push origin main
+
+# 2. Pull on follower
+ssh aitbc1 'cd /opt/aitbc && git pull origin main'
+
+# 3. Pull on gitea-runner
+ssh gitea-runner 'cd /opt/aitbc && git pull origin main'
+
+# 4. Verify sync
+# (use check status command above)
+```
+
+### Handle Sync Conflicts
+```bash
+# If git pull fails on remote node:
+ssh aitbc1 'cd /opt/aitbc && git checkout --force . && git clean -fd && git pull origin main'
+ssh gitea-runner 'cd /opt/aitbc && git checkout --force . && git clean -fd && git pull origin main'
+```
+
+### Service Restart After Sync
+```bash
+# Restart services that need code updates
+ssh aitbc1 'systemctl restart aitbc-agent-coordinator.service'
+ssh aitbc1 'systemctl restart aitbc-blockchain-node.service'
+ssh gitea-runner 'systemctl restart aitbc-blockchain-node.service'
+```
+
+## Best Practices
+
+1. Always verify git status on all nodes before major changes
+2. Push to Gitea first, then pull on remote nodes
+3. Use `--force-with-lease` instead of `--force` when needed
+4. Restart affected services after code sync
+5. Verify service health after sync and restart
