Skills Acquisition: How One Litigator Uses Claude to Build His Case Strategy

Summary Jared Correia sits down with Luis Vargas Rivera, head of litigation at Embedded Counsel, to unpack a problem most solo and small firm litigators never get to solve: a real moot before a hearing. Luis built a Claude skill called Adversarial Review that simulates a three-judge panel, each with a different mindset, to attack his motions before a judge ever does. From there, the conversation covers AI accountability and Rule 11, Luis's move from big law to a boutique firm, why marketing to referral sources beats paid ad spend, and how cross-practice litigation experience wins cases other lawyers can't see. They close on a shared obsession with a concept album about The Odyssey. Key Takeaways A Claude skill can run a three-persona Adversarial Review panel, a fact-focused judge, a procedural judge, and a pragmatist judge, that pressure tests a motion before oral argument. Citation tools like Lexis and Westlaw confirm your sources are accurate; they don't tell you where your argument is weakest. That's a different job. AI hallucinations are an accountability problem, not a technology problem. Rule 11 already requires lawyers to investigate what they sign, AI just removes the excuse for skipping that step. Marketing to other lawyers as referral sources can outperform paid ad spend aimed directly at clients, especially in crowded practice areas. Cross-practice litigation experience, moving ideas from civil litigation into a probate case, for example, can produce solutions opposing counsel doesn't see coming.
