Contract Analyzer

Review contracts to surface risks, key terms, and unusual provisions, then recommend negotiation actions.

references/key-terms.md -- full checklist of terms to extract by category
references/risk-flags.md -- red/yellow flags, standards comparison, commonly missing clauses
references/output-template.md -- the full analysis report format
references/examples.md -- worked examples and best practices

Workflow

Include this disclaimer in every output: "Legal Disclaimer: This is informational analysis only, not legal advice. Always consult with a qualified attorney for legal matters. Contract interpretation can be complex and jurisdiction-specific."
Identify the contract type (employment, independent contractor/freelance, NDA, service, partnership, software license, real estate, purchase).
Extract key terms across financial, duration/termination, intellectual property, liability/indemnification, and other critical categories. See references/key-terms.md.
Flag concerning clauses as red flags (high risk) or yellow flags (review carefully). See references/risk-flags.md.
Compare terms to industry standards: note deviations, one-sided provisions, and missing standard protections. See references/risk-flags.md.
Assess balance: determine whether obligations, penalties, and protections are reciprocal or favor one party.
Provide actionable recommendations: specific clauses to negotiate, alternative language, questions to ask, terms to add, and deal-breakers.
Format the report per references/output-template.md. For worked examples and best practices, see references/examples.md.
