What it does
Published by the Polish law firm Żurawska Piotrowski i Wspólnicy (KTZR), this skill makes Claude work on contracts in Polish, under the Civil Code, Copyright Act and GDPR.
- Nine workflows: fast triage (GREEN/YELLOW/RED), full five-stage analysis, risk audit, contract generator, terms-of-service generator, opposing-party "devil's advocate" review, single-clause editing, new-client onboarding, and cross-reference consistency verification.
- House standards: 12 Golden Rules plus 12 operating rules (R1–R12), a 15-point completeness checklist, an Art. 28 GDPR DPA audit grid, essentialia negotii mapping, mandatory-law (ius cogens) list, a 24-file clause library and 13 doctrine/case-law notes.
- Safety gates: a hard gate before any final document (verify party data, verify statutory citations, confirm the responsible lawyer reviewed the draft), STOP after every stage, and a layperson mode that only emits
[DRAFT]versions. - Anti-hallucination: with the
legal-citeMCP server running,verify_article()is mandatory before quoting any provision; without it every citation must be tagged[NIEZWERYFIKOWANE].
Who it's for
- Polish attorneys (radca prawny/adwokat) and in-house counsel reviewing or drafting contracts.
- IT vendors and clients negotiating Polish B2B, body-leasing, SaaS or IP-transfer agreements.
- Anyone who needs systematic detection of broken cross-references, inconsistent amounts and inconsistent defined terms in long contracts.
- Little value if you don't work with Polish-language documents.
Examples
- "Quick check — can I sign this NDA?" → triage workflow returns GREEN/YELLOW/RED with headline risks in 5–10 minutes.
- Paste a full body-leasing agreement → risk table with 🔴/🟠/🟡/🟢 levels, clause locations (§), fix recommendations and computed liability cap / total penalty exposure.
- "Draft SaaS terms of service" → cold-start interview, outline, clause-by-clause drafting, final version only after the pre-delivery gate.
- A 25-page contract → the two-pass verification workflow (inventory, then check each reference individually) catches wrong pointers like "pursuant to § 8(3)" and inconsistent capitalisation of defined terms.
