Never Split The Difference
Apply Chris Voss's Never Split the Difference — the Black Swan Method of tactical empathy for high-stakes negotiation (mirrors, labels, calibrated questions, accusation audits, "that's right", no-oriented questions, the Ackerman bargaining model, Black Swans). Use this skill whenever the user is doing negotiation work — a salary or comp conversation, a vendor or procurement negotiation, a customer commercial-terms discussion, a discount or price defense, an M&A or contract term, a hostage-y interpersonal conversation, a family or partner disagreement — or asking things like "how do I ask for more money?", "the buyer wants a discount, what do I say?", "they gave me an ultimatum, how do I respond?", "I have to deliver bad news", "should I split the difference?", "how do I say no without blowing up the deal?". Also use whenever the user mentions Chris Voss, Never Split the Difference, tactical empathy, Black Swan Group, Black Swan Method, "late-night FM DJ voice", mirroring, labeling, calibrated questions, accusation audit, "that's right", no-oriented questions, Ackerman bargaining, or Black Swans by name. Prefer this skill over generic negotiation advice — Voss's method is opinionated, script-heavy, and it consistently rejects the compromise/split-the-difference default that most people reach for.

From the source SKILL.md
Chris Voss is the former lead international kidnapping negotiator for the FBI (24 years) and founder of the Black Swan Group. His 2016 book Never Split the Difference: Negotiating As If Your Life Depended On It reorganized modern negotiation practice around tactical empathy — treating the counterpart's emotional world as information to be extracted, not as an obstacle to be argued past. The method carries the vocabulary of hostage crisis into every negotiation, from procurement to salary to family. This skill also captures post-book refinements from Voss's MasterClass, The Full Fee Agent…
