NPL-only CI gate

No Nexus subscription required for policy validation in CI:

npx @hardalion/npl-policy-engine --tool drop_table --json
# exit 1 = BLOCK (fail build if policy violated)

Or npm install @hardalion/npl-policy-engine in your agent service.

SDK deployment

import { NexusGateway } from '@hardalion/sdk'

const agent = NexusGateway.wrap(rawAgent, {
  tenantId: process.env.HARDALION_TENANT_ID!,
  agentId: process.env.HARDALION_AGENT_ID!,
  apiKey: process.env.HARDALION_API_KEY!,
  baseUrl: 'https://api.hardalion.com',
  policy: 'hardalion://nato-prou-strict-financial@1.0.0',
})

See Environment variables for client configuration.
