docs: add YAML frontmatter to skill files to make them proper skills

- Add YAML frontmatter to aitbc-ai-operations.md
- Add YAML frontmatter to aitbc-basic-operations.md
- Add YAML frontmatter to aitbc-blockchain-troubleshooting.md
- Add YAML frontmatter to aitbc-marketplace.md
- Add YAML frontmatter to aitbc-multi-node-operations.md
- Add YAML frontmatter to aitbc-node-coordination.md
- aitbc-cli.md and aitbc.md already had YAML frontmatter
- All 8 skill files now have proper YAML frontmatter for Hermes agents to load

+
+# AITBC Basic Operations Skill
+
+## Trigger Conditions
+Activate when user requests basic AITBC operations: CLI validation, wallet operations, blockchain status, service health checks, or system verification.
+
+## Purpose
+Test and validate AITBC basic CLI functionality, core blockchain operations, wallet operations, and service connectivity.
+
+## Prerequisites
+- AITBC CLI accessible at `/opt/aitbc/aitbc-cli`
+- Python venv activated for CLI operations
+- Services running on ports 8011 (coordinator), 8001 (exchange), 8006 (blockchain RPC)
+- Working directory: `/opt/aitbc`
+- Default test wallet: "genesis" with password from `/var/lib/aitbc/keystore/.genesis_password`
+
+## Operations
+
+### CLI Validation
+```bash
+# Check CLI version
+./aitbc-cli --version
+
+# Check CLI help
+./aitbc-cli --help
+```
+
+### Wallet Operations
+```bash
+# List wallets
+./aitbc-cli list
+
+# Check wallet balance
+./aitbc-cli balance --name genesis
+
+# Create test wallet
+./aitbc-cli create --name test-wallet --password "test123"
+```
+
+### Blockchain Operations
+```bash
+# Get blockchain info
+./aitbc-cli chain
+
+# Get network status
+./aitbc-cli network
+
+# Get analytics
+./aitbc-cli analytics --type blocks --limit 10
+```
+
+### Service Health Checks
+```bash
+# Check coordinator API (port 8011)
+curl http://localhost:8011/health
+
+# Check exchange API (port 8001)
+curl http://localhost:8001/health
+
+# Check blockchain RPC (port 8006)
+curl http://localhost:8006/health
+```
+
+## Common Pitfalls
+
+1. **CLI Not Found:** Ensure `/opt/aitbc/aitbc-cli` exists and is executable
+2. **Wallet Not Found:** Check wallet name spelling, verify keystore directory at `/var/lib/aitbc/keystore/`
+3. **Service Unreachable:** Verify services are running: `systemctl status aitbc-*`
+4. **Port Mismatch:** Coordinator API is on port 8011 (not 8000)
+5. **Password Required:** Use password from `/var/lib/aitbc/keystore/.genesis_password` for genesis wallet
+
+## Verification Checklist
+- [ ] CLI responds to `--version` and `--help`
+- [ ] Wallet list shows available wallets
+- [ ] Balance check returns valid AIT amount
+- [ ] Blockchain info shows current height and hash
+- [ ] Network status shows peer connections
+- [ ] All three services (coordinator, exchange, blockchain) return healthy status
+
+## CLI Tool Preference
+- **Primary CLI:** `/opt/aitbc/aitbc-cli` is the single CLI entry point
+- **Module:** `cli/unified_cli.py` is a module within the CLI tool for marketplace and messaging operations
+- **Note:** For marketplace operations, prefer `python3 cli/unified_cli.py` (verified working with 7 bugs fixed)
