📦 Quick Start

Installation

npm install @neural-trader/agentic-accounting-core

Basic Usage

import {
  TransactionIngestionService,
  TaxLossHarvestingService,
  PositionManager,
  ComplianceRuleEngine
} from '@neural-trader/agentic-accounting-core';

// 1. Ingest transactions
const ingestion = new TransactionIngestionService();
const result = await ingestion.ingestBatch(transactions, {
  source: 'coinbase',
  batchSize: 1000,
  validateOnIngestion: true,
  autoNormalize: true
});

console.log(`Ingested ${result.successful} transactions in ${result.duration}ms`);

// 2. Track positions
const positionManager = new PositionManager();
await positionManager.processBatch(result.transactions);
const positions = await positionManager.getAllPositions();

// 3. Find tax-loss harvesting opportunities
const harvesting = new TaxLossHarvestingService();
const opportunities = await harvesting.scanOpportunities(
  positions,
  currentPrices,
  recentTransactions,
  0.35 // 35% tax rate
);

console.log(`Found ${opportunities.length} harvesting opportunities`);
opportunities.forEach(opp => {
  console.log(`${opp.asset}: Save $${opp.potentialTaxSavings} (${opp.recommendation})`);
});

// 4. Validate compliance
const compliance = new ComplianceRuleEngine();
await compliance.loadRules('US', 'federal');
const violations = await compliance.checkTransactions(result.transactions);

if (violations.length > 0) {
  console.warn(`Found ${violations.length} compliance issues`);
}

📚 Detailed Tutorial

Step 1: Set Up Database

The core library uses PostgreSQL for transaction storage and AgentDB for vector search.

import { DatabaseConnection } from '@neural-trader/agentic-accounting-core';

// Initialize database
const db = new DatabaseConnection({
  host: 'localhost',
  port: 5432,
  database: 'accounting',
  user: 'postgres',
  password: process.env.DB_PASSWORD
});

await db.connect();

// Run migrations
import { runMigrations } from '@neural-trader/agentic-accounting-core/database';
await runMigrations(db, 'up');

Step 2: Ingest Transactions

import {
  TransactionIngestionService,
  NormalizationService,
  ValidationService
} from '@neural-trader/agentic-accounting-core';

const ingestion = new TransactionIngestionService();

// From CSV
const csvResult = await ingestion.ingestFromCSV('./transactions.csv');

// From API (Coinbase)
import { CoinbaseIntegration } from '@neural-trader/agentic-accounting-core/integrations';
const coinbase = new CoinbaseIntegration({ apiKey: process.env.COINBASE_API_KEY });
const coinbaseTransactions = await coinbase.fetchTransactions({
  startDate: new Date('2024-01-01'),
  endDate: new Date('2024-12-31')
});

const result = await ingestion.ingestBatch(coinbaseTransactions, {
  source: 'coinbase',
  batchSize: 1000,
  validateOnIngestion: true
});

console.log(`Processed ${result.successful}/${result.total} transactions`);

Step 3: Position Tracking

import { PositionManager } from '@neural-trader/agentic-accounting-core';

const manager = new PositionManager({
  defaultMethod: 'HIFO', // FIFO, LIFO, HIFO, AVERAGE, SPECIFIC
  enableReasoningBank: true
});

// Process transactions to build positions
await manager.processBatch(transactions);

// Query positions
const btcPosition = await manager.getPosition('BTC');
console.log(`BTC: ${btcPosition.quantity} @ avg cost $${btcPosition.averageCost}`);

// Get all positions
const allPositions = await manager.getAllPositions();
console.log(`Tracking ${allPositions.length} positions`);

// Calculate unrealized P&L
const currentPrices = new Map([
  ['BTC', 45000],
  ['ETH', 3000]
]);

const pnl = await manager.calculateUnrealizedPnL(currentPrices);
console.log(`Unrealized P&L: $${pnl}`);

Step 4: Tax-Loss Harvesting

import { TaxLossHarvestingService } from '@neural-trader/agentic-accounting-core';

const harvesting = new TaxLossHarvestingService();

// Scan for opportunities
const opportunities = await harvesting.scanOpportunities(
  positions,
  currentPrices,
  recentTransactions,
  0.35 // Tax rate
);

// Filter harvestable opportunities
const harvestable = opportunities.filter(o => o.recommendation === 'HARVEST');

console.log(`Harvestable opportunities: ${harvestable.length}`);

// Check wash sale violations
for (const opp of harvestable) {
  const washSaleCheck = await harvesting.checkWashSale(
    opp.asset,
    recentTransactions
  );

  if (washSaleCheck.hasViolation) {
    console.warn(`${opp.asset}: Wash sale violation - wait ${washSaleCheck.daysUntilSafe} days`);
  }
}

// Find replacement assets
const replacements = await harvesting.findReplacementAssets('BTC', 0.7);
console.log(`BTC replacements: ${replacements.join(', ')}`);

// Generate execution plan
const plan = await harvesting.generateExecutionPlan(opportunities);
console.log(`Execution plan: ${plan.recommendedHarvests} harvests for $${plan.totalPotentialSavings} savings`);

Step 5: Compliance Validation

import { ComplianceRuleEngine } from '@neural-trader/agentic-accounting-core';

const compliance = new ComplianceRuleEngine({
  enableReasoningBank: true,
  autoLearn: true
});

// Load rules for jurisdiction
await compliance.loadRules('US', 'federal');
await compliance.loadRules('US', 'state', 'CA');

// Validate transactions
const violations = await compliance.checkTransactions(transactions);

console.log(`Compliance violations: ${violations.length}`);

violations.forEach(v => {
  console.log(`Rule ${v.ruleId}: ${v.description}`);
  console.log(`  Transaction: ${v.transactionId}`);
  console.log(`  Severity: ${v.severity}`);
  console.log(`  Recommendation: ${v.recommendation}`);
});

// Real-time monitoring
compliance.on('violation', async (violation) => {
  console.warn('NEW VIOLATION:', violation);
  // Send alert via email/Slack/etc
});

await compliance.startMonitoring(transactionStream);

Step 6: Tax Reporting

import { ReportGenerator } from '@neural-trader/agentic-accounting-core';

const reporter = new ReportGenerator();

// Generate IRS Form 8949
const form8949 = await reporter.generateForm8949({
  taxpayerId: '123-45-6789',
  taxYear: 2024,
  transactions: disposals,
  method: 'HIFO'
});

console.log(`Form 8949: ${form8949.totalDisposals} disposals`);
console.log(`Short-term gain/loss: $${form8949.shortTermGainLoss}`);
console.log(`Long-term gain/loss: $${form8949.longTermGainLoss}`);

// Export as PDF
await reporter.exportToPDF(form8949, './form-8949-2024.pdf');

// Generate Schedule D
const scheduleD = await reporter.generateScheduleD(form8949);

// Multi-jurisdiction report
const ukReport = await reporter.generateReport({
  jurisdiction: 'UK',
  reportType: 'capital_gains',
  taxYear: '2024/2025',
  transactions: disposals
});

Step 7: Forensic Analysis

import { ForensicAnalyzer } from '@neural-trader/agentic-accounting-core';

const forensics = new ForensicAnalyzer({
  enablePatternDetection: true,
  anomalyThreshold: 0.85
});

// Detect patterns
const patterns = await forensics.detectPatterns(transactions, {
  minSupport: 0.1,
  minConfidence: 0.6
});

console.log(`Found ${patterns.length} transaction patterns`);

// Identify anomalies
const anomalies = await forensics.identifyAnomalies(transactions);

anomalies.forEach(a => {
  console.log(`Anomaly detected: ${a.type}`);
  console.log(`  Transaction: ${a.transactionId}`);
  console.log(`  Score: ${a.score}`);
  console.log(`  Reason: ${a.reason}`);
});

// Fraud detection
const fraudScore = await forensics.calculateFraudScore(transaction);

if (fraudScore > 0.8) {
  console.warn(`HIGH FRAUD RISK: ${transaction.id} (score: ${fraudScore})`);
}

💡 Advanced Features

⚠️ Important Notes

Database Setup: PostgreSQL 12+ required. Run migrations before first use.

Performance: First calculation is slower (~100ms) due to Rust NAPI initialization. Subsequent calls are <1ms.

Wash Sales: 30-day window enforced. Check washSaleRisk before executing harvests.

💡 Pro Tips

Tip: Use batchSize: 1000 for optimal ingestion performance. Larger batches may cause memory issues.

Tip: Enable enableReasoningBank: true to leverage learned patterns from previous decisions.

Tip: Call invalidateCache() after updating positions to ensure fresh calculations.

🎯 Best Practices

Note: Always validate transactions before processing to catch data quality issues early.

Note: Use HIFO method for tax-loss harvesting to maximize savings.

Note: Run compliance checks daily in production environments.
