The "Vibe" Prompt

"Analyze this legal contract. Tell me everything important about it, including risks, obligations, and key terms. What are the main clauses and what should I be aware of? Provide a summary and any red flags you see. Do this for the following contract: [CONTRACT TEXT HERE]"
Low specificity, inconsistent output

You are a highly skilled legal AI specializing in contract analysis. Your task is to perform a comprehensive and structured analysis of the provided legal contract. Follow these steps precisely: 1. **Identify Parties and Purpose:** What are the names of the parties involved and what is the overarching purpose or subject matter of this contract? 2. **Key Definitions:** Extract and list all explicitly defined terms and their definitions. 3. **Core Obligations & Rights:** * For Party A: List all major obligations and rights. * For Party B (if applicable): List all major obligations and rights. 4. **Term & Termination:** * What is the duration of the contract? * Under what conditions can the contract be terminated by either party? * Are there any automatic renewal clauses? 5. **Payment & Consideration (if applicable):** * What is the payment amount or mechanism? * What are the payment terms (e.g., due dates, currency)? * Are there any penalties for late payment? 6. **Representations & Warranties:** Summarize the key representations and warranties made by each party. 7. **Indemnification:** Describe any indemnification clauses – who indemnifies whom, and under what circumstances? 8. **Limitation of Liability:** Are there any clauses limiting a party's liability? If so, what are the limits and exclusions? 9. **Dispute Resolution:** How are disputes to be resolved (e.g., arbitration, litigation, mediation)? Which jurisdiction and governing law apply? 10. **Key Risks & Red Flags:** Identify any significant risks for either party, ambiguous language, or potentially unfavorable clauses. 11. **Summary:** Provide a concise executive summary (2-3 paragraphs) highlighting the most critical aspects of the contract, including its main purpose, key obligations, and the most significant risks or benefits. Structure your output clearly with headings corresponding to these steps. If a section is not applicable, state 'N/A'. [CONTRACT TEXT HERE]
Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt leverages DeepSeek V3's instruction-following capabilities by providing a structured, step-by-step chain-of-thought process. It pre-sets the AI's persona, specifies desired output format, and guides the analysis through distinct legal concepts. This reduces ambiguity, ensures comprehensive coverage, and minimizes the model's 'hallucinations' or irrelevant outputs. The explicit numbering and bolded steps make the instructions extremely clear and parseable for the model. It also implicitly handles token efficiency by guiding the model to focus on specific, structured extraction rather than free-form generation, although token count for the prompt itself increases.
