An AI agent making purchases under different policies. Same transactions, different policy outcomes.

index.ts

import { evaluate, balanced, aggressive, riskAverse } from '@vanar/xbpp'

const purchases = [
  { amount: 25, currency: 'USDC', recipient: 'api.openai.com' },
  { amount: 150, currency: 'USDC', recipient: 'cloud.google.com' },
  { amount: 5000, currency: 'USDC', recipient: 'aws.amazon.com' },
]

// Under balanced policy
purchases.forEach(p => {
  const v = evaluate(p, balanced)
  console.log(`${p.amount} → ${v.decision}`)
})
// $25  → ALLOW
// $150 → ESCALATE (above askMeAbove: $100)
// $5000 → BLOCK (exceeds maxSingle: $100)

output

$25 to api.openai.com → ALLOW
$150 to cloud.google.com → ESCALATE
  reason: ABOVE_ESCALATION_THRESHOLD
$5000 to aws.amazon.com → BLOCK
  reason: EXCEEDS_SINGLE_LIMIT
