+## 🤝 H&&S (Handshake & Sign) Protocol
+
+**NEW**: Multi-agent workflow coordination with verifiable state transitions.
+
+```bash
+# Install dependencies
+npm install
+
+# Create a handoff
+node dist/cli.js handoff create \
+  --from claude --to grok \
+  --state WAVE \
+  --context '{"phase":"exploration"}' \
+  --score 88
+
+# View workflow chain
+node dist/cli.js handoff chain <session-id>
+
+# Generate Mermaid visualization
+node dist/cli.js handoff viz <session-id> --output workflow.svg
+```
+
+**Documentation**: See [docs/HANDSHAKE_PROTOCOL.md](docs/HANDSHAKE_PROTOCOL.md)
+
+**Features**:
+- ✅ Agent-to-agent coordination (WAVE, PASS, BLOCK, HOLD, PUSH states)
+- ✅ ATOM trail integration for auditing
+- ✅ Workflow visualization via Mermaid
+- ✅ High performance (1000 handoffs <500ms)
+- ✅ TypeScript with 92%+ test coverage
