What this is good for

The aggregator (@czagents/dd) was built for one specific recurring chore: checking new business partners before signing or paying. The kinds of prompts it handles well:

• KYC pre-invoice — "Before we send a 350 000 Kč invoice to IČO 27074358, flag any insolvency, sanctions, unreliable-VAT-payer status, or nominee-director red flags."
• Vendor onboarding — "Run KYC on this prospective supplier and tell me if anything looks off. Use the full statutory chain."
• M&A pre-due-diligence — "Generate a DD report on the acquisition target and walk the statutory body two levels deep — flag any insolvent firms in the network."
• Bookkeeping triage — "For these 12 incoming invoices, screen each issuer's IČO against EU sanctions and active insolvency. Sort by risk."

The standalone packages (@czagents/ares, cnb, sanctions, isir) are thinner — useful when you only need one specific data source, or when you're building your own custom workflow on top.
