Overview

This skill enables creation of smart contract templates using Accord Project - an open-source framework for legally enforceable, machine-readable contracts. Create templates with embedded logic that can automate contract execution.

How to Use

1. Describe the contract type and terms
2. Specify variables and logic rules
3. I'll generate Accord Project template

Example prompts:

• "Create an NDA template with variable terms"
• "Build a service agreement with payment milestones"
• "Generate a rental agreement template"
• "Design a consulting contract with termination clauses"

and [{buyer}] ("Buyer").

## Services

## Payment
The Buyer shall pay [{paymentAmount}] within 
[{paymentDays}] days of invoice.

## Term

and continues for [{termMonths}] months.

## Late Payment
A penalty of [{penaltyPercent}]% applies to late payments.
{{/if}}

Data Model (Concerto)

namespace org.example.service

import org.accordproject.time.*

asset ServiceAgreement extends Contract {
  o String supplier
  o String buyer
  o String serviceDescription
  o Double paymentAmount
  o Integer paymentDays
  o DateTime startDate
  o Integer termMonths
  o Boolean latePenalty optional
  o Double penaltyPercent optional
}

transaction PaymentRequest {
  o Double amount
  o DateTime dueDate
}

transaction PaymentResponse {
  o Double amount
  o Double penalty
  o DateTime paymentDue
}

Business Logic (Ergo)

namespace org.example.service

import org.accordproject.time.*

contract ServiceContract over ServiceAgreement {
  
  clause payment(request : PaymentRequest) : PaymentResponse {
    let dueDate = addDuration(request.dueDate, 
                              Duration{ amount: contract.paymentDays, unit: ~org.accordproject.time.TemporalUnit.days });
    
    let penalty = 
      if contract.latePenalty
      then request.amount * contract.penaltyPercent / 100.0
      else 0.0;
    
    return PaymentResponse{
      amount: request.amount,
      penalty: penalty,
      paymentDue: dueDate
    }
  }
}
