Use this skill whenever the user wants help with anything related to selling, persuading, or closing deals. This includes: writing sales scripts, crafting commercial proposals, handling objections, structuring cold outreach messages, pitching software or tech products, negotiating prices, writing follow-up messages, creating elevator pitches, framing value propositions, or coaching on how to close a deal. Trigger this skill even for partial or casual requests like "how do I convince my client?", "write me a pitch", "my client said it's too expensive — what do I say?", "help me sell this", or any situation where the goal is to move someone toward a buying decision. Covers B2B and B2C contexts, with special depth for software, SaaS, and tech products.
