Built on the CUAD dataset (41 risk categories), ContractEval benchmarks, and LegalBench.\n\n## When to Activate\n\n- User mentions \"review contract\", \"analyze agreement\", \"check this contract\"\n- User uploads or references a PDF/DOCX legal document\n- User asks about specific clauses, risks, or terms\n\n---\n\n## Step 1: Pre-Review Checklist\n\nBefore analyzing content, verify document completeness:\n\n- [ ] **Blank fields**: Flag any \"$X\", \"TBD\", \"[amount]\", \"____\" placeholders\n- [ ] **Missing exhibits**: List all referenced schedules/exhibits and note which are missing\n- [ ] **Signature status**: Draft or already executed?\n- [ ] **All pages present**: Check for truncation or missing sections\n\nIf blank fields or missing exhibits exist, flag prominently in output header.\n\n---\n\n## Step 2: Identify Document Type & User Position\n\n**Ask if unclear:** \"Which party are you? (customer, vendor, buyer, seller, licensor, licensee, receiving party, disclosing party)\"\n\nThis affects what's \"risky\":\n- Customer reviewing vendor agreement → flag vendor-favorable terms\n- Vendor reviewing own template → flag customer-favorable terms\n- Buyer in M&A → flag seller-favorable terms\n- Seller in M&A → flag buyer-favorable terms\n- Receiving party in NDA → flag disclosing party-favorable terms\n\n**Assess power dynamic:**\n- Startup vs. large enterprise? (limited negotiating leverage)\n- Standard form vs. negotiated? (some terms non-negotiable)\n- Regulated industry? (some terms legally required)\n\n---\n\n## Output Format\n\nUse **markdown** for readable, scannable output. Do NOT use XML tags.\n\n---\n\n### Example Output\n\n```markdown\n# Contract Review: [Document Name]\n\n**Document Type:** SaaS Subscription Agreement\n**Your Position:** Customer\n**Counterparty:** Acme Software Inc.\n**Risk Level:** 🟡 Medium\n**Document Status:** Draft / Executed on [date]\n\n## ⚠️ Pre-Signing Alerts\n\n- **Blank field:** Fee amount in Section 4.1 is \"$____\"\n- **Missing exhibit:** Exhibit B (SLA) referenced but not attached\n\n## Executive Summary\n\nStandard vendor agreement with some one-sided terms.

Rating | Meaning | Examples |\n|--------|---------|----------|\n| **High** | Usually accepted | Mutual termination, cure periods, data export |\n| **Medium** | Depends on leverage | Liability cap increase, price caps |\n| **Low** | Rarely changed | Network rules (payments), regulatory requirements |\n| **None** | Non-negotiable | Card network mandates, banking regulations |\n\n**Power dynamic factors:**\n- Large customer + small vendor = more leverage\n- Startup + enterprise vendor = less leverage\n- Competitive market = more leverage\n- Sole-source vendor = less leverage\n- Regulated terms = no leverage (legally required)\n\n---\n\n## Jurisdiction Notes\n\n**Non-Competes:**\n- California, North Dakota, Oklahoma, Minnesota: Generally void\n- Other states: Reasonableness test applies\n\n**Choice of Law:**\n- Delaware: Corp-friendly, predictable\n- New York: Financial agreements, sophisticated courts\n- California: Employee-friendly, tech industry\n- BVI/Cayman: Offshore, expensive to litigate, potential red flag\n\n**Arbitration Venues:**\n- AAA, JAMS: Standard US commercial\n- SIAC (Singapore), LCIA (London): International, expensive\n- Mandatory + class waiver: Limits remedies significantly\n\n---\n\n## Guardrails\n\n- **Not legal advice**: Recommend attorney review for material terms\n- **Not tax advice**: Flag but don't opine\n- **Jurisdiction matters**: Note when enforceability varies\n- **Express uncertainty**: Say when interpretation is unclear\n- **No hallucination**: Only reference text actually in document\n- **Show what's acceptable**: Always include \"Reviewed & Acceptable\" section\n- **Document status matters**: Note if already executed (review is
