### What is it?

Agent Commercial Contract is a comprehensive smart contract framework that enables AI agents to autonomously negotiate, sign, execute, and enforce commercial agreements. It provides the legal and financial infrastructure necessary for agent-to-agent commerce.

---

### Core Capabilities

**Contract Management**
- Create legally-binding contracts from templates or custom terms
- Multi-party digital signatures with cryptographic verification
- Automated contract lifecycle (draft → signed → active → completed)
- Milestone-based execution with deliverable tracking
- Full audit trail of all contract events

**Agent Identity & Authentication**
- Cryptographic identity system with public/private key pairs
- Digital signature generation and verification
- API key-based authentication
- Capability-based access control

**Escrow & Payment**
- Automated payment holding in secure escrow accounts
- Milestone-based fund release mechanisms
- Refund and dispute handling
- Multi-currency support
- Complete transaction history

**Dispute Resolution**
- Structured dispute raising with evidence submission
- Arbitrator assignment (human or AI)
- Evidence verification with cryptographic hashing
- Automated compensation calculation
- Resolution enforcement

---

### When to Use This Skill

**AI Agent Marketplaces**
Build marketplaces where AI agents can buy and sell services with automatic contract enforcement.

**Multi-Agent Collaboration**
Enable multiple agents to work together on projects with clear terms, milestone-based payments, and automated conflict resolution.

**API-as-a-Service Networks**
Create networks where agents monetize their APIs with usage tracking, billing automation, and SLA enforcement.

**Data Exchange Platforms**
Build secure platforms for agents to buy/sell datasets with quality guarantees, escrow protection, and provenance tracking.

---

### Quick Start

**Installation**:
```bash
npm install agent-commercial-contract
```

**Basic Usage**:
```typescript
import AgentCommercialContract from 'agent-commercial-contract';

const sdk = new AgentCommercialContract();

// Register agents
const provider = await sdk.identity.registerAgent('Provider AI', ['data-processing']);
const consumer = await sdk.identity.registerAgent('Consumer AI', ['analytics']);

// Create contract with escrow
const result = await sdk.createContractWithEscrow(
  provider.data.identity,
  consumer.data.identity,
  {
    title: 'Data Processing Service',
    service: { type: 'data-processing', specification: '...' },
    payment: { amount: 5000, currency: 'USD', structure: 'milestone' },
    timeline: { duration: 30 },
  }
);
```

**CLI Commands**:
```bash
# Register agent
agent-contract agent register --name "My Agent" --capabilities "data-processing"

# Create contract
agent-contract contract create \
  --provider agent_xxx \
  --consumer agent_yyy \
  --title "Service Agreement" \
  --amount 1000 \
  --with-escrow

# View dashboard
agent-contract dashboard --agent agent_xxx
```

### Integration with AI Agents

**Autonomous Agent Workflow**:
```typescript
class AutonomousAgent {
  constructor(private sdk: AgentCommercialContract) {}

  async offerService() {
    await this.sdk.identity.registerAgent('My Service Bot', ['data-processing']);
  }

  async acceptContract(contractId: string) {
    const contract = this.sdk.contracts.getContract(contractId);
    if (this.canFulfill(contract)) {
      const signature = this.generateSignature(contract);
      await this.sdk.contracts.signContract({
        contractId,
        agentId: this.agentId,
        signature,
        credentials: this.credentials,
      });
    }
  }

  async deliverWork(contractId: string, milestoneId: string) {
    await this.sdk.completeMilestoneAndPay(contractId, milestoneId, this.agentId);
  }
}
```

### Security & Best Practices

**Cryptographic Security**:
- RSA 2048-bit keys for digital signatures
- SHA-256 hashing for evidence integrity
- Secure key storage recommendations
- API key rotation support

**Legal Enforceability**:
- Digital signatures legally binding
- Jurisdiction specification in contracts
- Audit trails for compliance
- Dispute resolution mechanisms

**Best Practices**:
- Never commit private keys to version control
- Use environment variables for sensitive data
- Implement key rotation policies
- Maintain comprehensive audit logs
- Test contracts in staging environment first
