About
Contract Review is an AI-backed contract analysis skill that identifies risks, checks completeness, and provides actionable negotiation recommendations. Supports employment contracts, NDAs, service agreements, leases, and more across US, EU, China, and UK jurisdictions. Developers and contract reviewers use it to extract text from PDF/DOCX files, analyze contract structure via MCP tools, identify 15+ common risk patterns (unlimited liability, broad IP assignment, unilateral termination, one-sided indemnification, perpetual confidentiality), check for missing essential elements (parties, effective date, term, scope, compensation, termination, confidentiality, IP, liability limits, governing law, dispute resolution), and produce markdown reports with risk summaries, detailed findings, completeness checklists, and negotiation priorities. Includes jurisdiction-specific knowledge bases for employment law variations, data protection requirements, and enforceability rules. Works with Claude Sonnet-4, Claude Opus-4, GPT-4, and GPT-4o models.

How to Use Me
Step 1: Share Your Contract
Upload your contract file (PDF, DOCX, or paste text) and tell me:
- What type of contract is this? (employment, NDA, service, lease, etc.)
- Which party are you? (employee, contractor, buyer, seller, etc.)
- What jurisdiction/country?
- Any specific concerns?
Step 2: I Will Analyze
I'll review the contract and provide: 1. Risk Summary - High/Medium/Low risks found 2. Clause Analysis - Specific problematic clauses 3. Completeness Check - Missing standard elements 4. Recommendations - What to negotiate or change
Step 3: Ask Follow-ups
Feel free to ask:
- "Explain Section 5 in simple terms"
- "What's the worst case if I sign this?"
- "How do I negotiate the non-compete clause?"
- "Is this normal for [industry]?"

Risk Patterns I Look For
High Risk (Red Flags)
1. Unlimited Liability
What it means: You could be responsible for unlimited damages. Look for: "unlimited liability", "full indemnification", no liability cap Recommendation: Add liability cap (e.g., 12 months of fees, or contract value)
2. Broad IP Assignment
What it means: You give away all intellectual property, including work you did before. Look for: "all intellectual property", "work product", "inventions", "work for hire" Recommendation: Exclude pre-existing IP; define scope clearly; check state protections (CA Labor Code 2870)
3. Unilateral Termination
What it means: The other party can end the contract anytime, but you can't. Look for: "at will", "unilateral termination", "without cause", "sole discretion" Recommendation: Require mutual termination rights or reasonable notice period
4. One-Sided Indemnification
What it means: Only you bear responsibility for problems, not them. Look for: "indemnify and hold harmless", "defend at own expense", "all claims" Recommendation: Negotiate mutual indemnification
5. Broad Rights Waiver
What it means: You give up legal rights you're entitled to. Look for: "waive", "waiver of rights", "release all claims", "forever discharge" Recommendation: Remove or limit scope; some waivers may be unenforceable
6. Missing Data Protection
What it means: No provisions for how personal data is handled (GDPR/CCPA risk). Look for: Absence of "personal data", "GDPR", "privacy", "data protection" Recommendation: Add data protection clause compliant with applicable laws
Medium Risk (Yellow Flags)
7. Auto-Renewal Trap
What it means: Contract renews automatically with difficult opt-out. Look for: "automatically renew", "unless written notice", "evergreen" Recommendation: Add clear opt-out with 30-day notice minimum
8. Excessive Penalty
What it means: Penalty for breach exceeds reasonable damages. Look for: "penalty", "liquidated damages", "forfeit" Recommendation: Ensure penalty is proportionate to actual damages
9. Broad Non-Compete
What it means: Restrictions on future work that are too broad. Look for: "non-compete", "non-competition", "competitive business" Recommendation: Limit to 1-2 years, specific geography, narrow scope Note: California: generally unenforceable; FTC proposing ban (pending)
10. Perpetual Confidentiality
What it means: Confidentiality obligations that never expire. Look for: "perpetual", "indefinite", "forever", "in perpetuity" Recommendation: Set reasonable time limit (3-5 years typical)
11. Unfavorable Jurisdiction
What it means: Disputes resolved in a place far from you or favoring them. Look for: "jurisdiction", "arbitration venue", "exclusive venue" Recommendation: Negotiate neutral venue or your local jurisdiction
12. Unfavorable Payment Terms
What it means: Long payment cycles or subjective acceptance criteria. Look for: "net 90", "upon satisfaction", "when commercially reasonable" Recommendation: Negotiate shorter cycles (net 30), objective acceptance criteria
13. Uncontrolled Scope Changes
What it means: No process for managing changes to work scope. Look for: "change order", "as directed", "scope change", "additional work" Recommendation: Add change management process with pricing mechanism
14. Missing Force Majeure
What it means: No provision for unforeseeable events (pandemic, disaster). Look for: Absence of "force majeure", "act of god" Recommendation: Add standard force majeure clause
Low Risk (Worth Noting)
15. Missing Audit Rights
What it means: No right to verify compliance or check records. Look for: Absence of "inspection", "audit rights", "records access" Recommendation: Add reasonable audit rights for significant contracts

Example Interactions
Example 1: Employment Contract Review
User: Review this employment contract. I'm the employee, this is for a US company in California.
Me: [After analysis]
Contract Analysis Report
Document: Employment Agreement Type: Employment Contract Jurisdiction: United States (California) Your Role: Employee
Risk Summary
| Severity | Count | Key Issues |
|---|---|---|
| 🔴 High | 2 | IP assignment too broad, No liability cap |
| 🟡 Medium | 3 | Non-compete (unenforceable in CA), Auto-renewal, Arbitration |
| 🟢 Low | 1 | No audit rights |
Overall Assessment: ⚠️ REVIEW NEEDED
Detailed Findings
🔴 High Risk Issues
1. Broad IP Assignment (Section 5.1)
"Employee assigns to Company all right, title and interest in any and all inventions, discoveries, and work product..."
- Problem: This assigns ALL inventions, including personal projects
- Impact: Even code you write on weekends for personal projects could belong to the company
- Recommendation: Add California Labor Code 2870 language: "This does not apply to inventions developed entirely on Employee's own time without using Company resources, unless related to Company's business."
2. Non-Compete Clause (Section 9)
"Employee agrees not to work for any competitor for 24 months after termination..."
- Problem: Attempts to restrict future employment
- Impact: In California, this is unenforceable under Business & Professions Code 16600
- Recommendation: Request removal. If they refuse, don't worry - it's void in CA anyway.
---
Example 2: Quick Question
User: Is a 3-year non-compete normal?
Me: No, 3 years is longer than typical. Here's the context:
| Duration | Assessment |
|---|---|
| 6 months | Short, usually reasonable |
| 1 year | Common, often enforceable |
| 2 years | Upper limit of reasonableness |
| 3 years | Excessive - likely unenforceable in many jurisdictions |
Important: In California, non-competes are void regardless of duration. Many other states require they be "reasonable" - 3 years usually fails this test.
Recommendation: Negotiate down to 1 year maximum, or request removal entirely.
---
Tips for Better Results
1. Tell me your role: Are you the employee, contractor, buyer, or seller? 2. Specify jurisdiction: US? Which state? EU? China? 3. Share context: Is this a job you really want? Big client? High stakes? 4. Ask follow-ups: I can explain any clause in more detail 5. Use me iteratively: Review → Negotiate → Review revised version
---
Limitations
- I provide general guidance, not legal advice
- My knowledge may not reflect the latest legal changes
- Some risks are industry-specific and may need expert review
- For high-stakes contracts (M&A, major deals), always use a lawyer
- I can't verify if the other party will actually follow the contract
