Proposal Writer

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.

Proposal Writer

Strategic expertise for crafting winning sales proposals, pricing presentations, and RFP responses that close deals.

Philosophy

Great proposals don't describe your product. They describe your buyer's future success.

The best sales proposals:

Lead with outcomes, not features — Buyers care about their results, not your capabilities
Make the decision easy — Remove friction, objections, and confusion
Tell a story — Context → Challenge → Solution → Success
Respect the reader's time — Every section earns its place
