Plan an outreach campaign — clarify who you are, what you sell, and who you're targeting, using the value-equation framing, and write a short reviewable campaign.md. Use whenever the user wants to start lead outreach, define an outreach goal/offer/ICP, or prep a list of leads for personalized email — before any lead is researched. Reads an existing context/brand folder if one is given (asks for the path if it can't find one). Also /leads-plan. NOT for researching individual leads (use leads-research) and NOT for sending email (use leads-deliver).
