## What it does

The skill loads when a task mentions finance, core banking, regulations or payments. It covers account management, transaction processing, loans and risk systems, plus regulation blocks on Basel III/IV, KYC, AML, GDPR, PSD2 and Dodd-Frank.

Python examples show how the pieces fit. An `Account` class with `deposit`, `withdraw` and `transfer` keeps balances in `Decimal` and rolls the debit back if the credit fails. `KYCService` folds identity, address, sanctions and PEP checks into one result with a risk level. `AMLMonitoring` flags large amounts, bursts of transactions and transfers to high-risk countries, then files a suspicious activity report.

Payments get their own section: ACH with routing number validation and SWIFT MT103. The skill is limited to `Read`, `Write` and `Edit`, so it will not run any of that code — worth knowing if you expect it to execute tests. The 10000 threshold in the monitoring example is an illustration, not a limit for your system.

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/personamanagmentlayer/pcl/tree/HEAD/stdlib/professional/banking-expert/SKILL.md

## When to use it
- split account operations into deposit, withdrawal and transfer with rollback
- combine identity, address, sanctions and PEP checks into one verification result
- flag suspicious transactions and file a report
- work out which Basel III/IV and PSD2 requirements apply to a task
- map the flow of an ACH payment or a SWIFT wire

## Example prompts
- Help me design a transfer service between accounts with rollback on a failed credit
- Which KYC checks are needed before opening an account? Combine them into one result
- Explain how AML monitoring flags large and high-velocity transactions

    CREDIT = "credit"
    LOAN = "loan"

class Account:
    def __init__(self, account_number: str, account_type: AccountType,
                 customer_id: str, balance: Decimal = Decimal('0')):
        self.account_number = account_number
        self.type = account_type
        self.customer_id = customer_id
        self.balance = balance
        self.status = "ACTIVE"
        self.created_at = datetime.now()

    def deposit(self, amount: Decimal) -> dict:
        """Deposit funds with validation"""
        if amount <= 0:
            raise ValueError("Amount must be positive")

        self.balance += amount

        return {
            "transaction_id": self.generate_transaction_id(),
            "type": "DEPOSIT",
            "amount": amount,
            "balance": self.balance,
            "timestamp": datetime.now()
        }

    def withdraw(self, amount: Decimal) -> dict:
        """Withdraw funds with balance check"""
        if amount <= 0:
            raise ValueError("Amount must be positive")

        if self.balance < amount:
            raise ValueError("Insufficient funds")

        self.balance -= amount

        return {
            "transaction_id": self.generate_transaction_id(),
            "type": "WITHDRAWAL",
            "amount": amount,
