This one teaches Claude to write sales proposals, pricing decks, SOWs, and RFP responses that actually close deals. It's built around the idea that proposals should show the buyer's future success, not list your features. You get frameworks for structuring everything from one-pagers to full RFP responses, plus tactical stuff like pricing presentation order, executive summary templates, and the CLOSE framework for each section. The anti-patterns list is solid, calling out common mistakes like price-first presentations and feature dumping. Useful if you're writing proposals regularly and want Claude to follow proven sales strategy instead of generating generic business docs.
