Use when retrieving arbitration institutional rules (ICC, LCIA, SCC, SIAC, HKIAC, VIAC, МКАС/МАК при ТПП України, UNCITRAL) — fetching current version, verifying redaction applicable to the date of arbitration agreement, constructing URLs for official rule texts
Use when choosing the Polish legal regime for letters, requests, applications, complaints, petitions, public-information requests, KPA filings, PPSA complaints, RODO access requests, registry extracts, court-file access, tax/ZUS/cudzoziemcy/USC procedures, or professional lawyer letters. Prevents mixing UDIP, KPA, PPSA, RODO, registry, special-procedure, and advocate/radca letter regimes.
Use when preparing applications for recognition and enforcement of foreign arbitral awards in Poland, applications for setting aside arbitral awards under KPC art. 1205–1211, or opposing such applications — mapping Article V of the 1958 New York Convention to art. 1214–1215 of the Polish KPC, identifying grounds for refusal, structuring public policy arguments

Extract key terms from the contracts at [file URL 1], [file URL 2], and [file URL 3], then generate a contract register spreadsheet. Use the extract_document tool with these fields:
- contracts (ARRAY): One entry per contract file, each with:
- contract_title (TEXT): Title or subject of the contract
- counterparty (TEXT): Name of the other contracting party
- effective_date (DATE): Date the contract becomes effective
- expiry_date (DATE): Date the contract expires or ends
- contract_value (CURRENCY_AMOUNT): Total or annual contract value if stated
- currency (CURRENCY_CODE): Currency of contract value
- auto_renewal (BOOLEAN): Whether the contract auto-renews
- governing_law (TEXT): Jurisdiction or governing law
Then use the generate_sheet tool to create an XLSX contract register with the extracted rows.
