AI Code Review and Validation

Overview

AI can assist code review by identifying obvious smells, missing null checks, or repetitive defects. Final approval should still depend on deterministic checks and human engineering review.

Practical Example - Add Defensive Validation

public sealed class TransferService
{
    public Task TransferAsync(decimal amount, string fromAccountId, string toAccountId, CancellationToken ct)
    {
        if (amount <= 0) throw new ArgumentOutOfRangeException(nameof(amount));
        if (string.IsNullOrWhiteSpace(fromAccountId)) throw new ArgumentException("Source account is required.", nameof(fromAccountId));
        if (string.IsNullOrWhiteSpace(toAccountId)) throw new ArgumentException("Destination account is required.", nameof(toAccountId));
        if (fromAccountId == toAccountId) throw new InvalidOperationException("Source and destination must differ.");

        return Task.CompletedTask;
    }
}
