+# AITBC Node Coordination Skill
+
+## Trigger Conditions
+Activate when user requests cross-node operations: synchronization, coordination, messaging, or multi-node status checks.
+
+## Purpose
+Coordinate cross-node operations, synchronize blockchain state, and manage inter-node messaging between genesis and follower nodes.
+
+## Prerequisites
+- SSH access configured between genesis (aitbc) and follower (aitbc1) with key-based authentication
+- Blockchain nodes operational on both nodes via systemd services
+- P2P mesh network active on port 7070 with peer configuration
+- Unique node IDs configured (proposer_id and p2p_node_id in `/etc/aitbc/.env` and `/etc/aitbc/node.env`)
+- Git synchronization configured between nodes at `/opt/aitbc/.git`
+
+## Operations
+
+### Check Multi-Node 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'
+```
+
+### 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'
+```
+
+### Check Blockchain Sync Status
+```bash
+# Check blockchain height on all nodes
+./aitbc-cli chain
+ssh aitbc1 'cd /opt/aitbc && ./aitbc-cli chain'
+ssh gitea-runner 'cd /opt/aitbc && ./aitbc-cli chain'
+```
+
+### Check Node Health
+```bash
+# Check service status on all nodes
+systemctl status aitbc-blockchain-node.service
+ssh aitbc1 'systemctl status aitbc-blockchain-node.service'
+ssh gitea-runner 'systemctl status aitbc-blockchain-node.service'
+```
+
+## Common Pitfalls
+
+1. **SSH Connectivity Issues:** Verify SSH keys are configured at `/root/.ssh/` for passwordless access
+2. **Git Conflicts:** Use `--force` flag with caution, prefer manual resolution
+3. **P2P Handshake Rejection:** Check for duplicate p2p_node_id, run `/opt/aitbc/scripts/utils/generate_unique_node_ids.py`
+4. **Service Restart Failures:** Check systemd logs: `journalctl -u aitbc-blockchain-node.service -n 50`
+5. **Sync Partial Failure:** Identify which sync type failed (blockchain, mempool, configuration, git)
+
+## Verification Checklist
+- [ ] SSH connectivity to all nodes verified
+- [ ] Git status consistent across all nodes
+- [ ] Blockchain heights match across nodes
+- [ ] P2P mesh network operational (port 7070)
+- [ ] Services running on all nodes
+- [ ] Node IDs unique (no duplicate p2p_node_id)
+
+## 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 (also hosts aitbc2 blockchain)
+
+## Git Remote Strategy
+- **Primary Remote:** `origin` (Gitea) - Daily development operations
+- **Secondary Remote:** `github` - Milestone releases only
+
+## CLI Tool Preference
+- **Primary CLI:** `/opt/aitbc/aitbc-cli` is the single CLI entry point
+- **SSH Access:** Use `ssh aitbc1` for follower node, `ssh gitea-runner` for CI/CD node
