Skill: react
Invoke this when users react disproportionately intensely to losing (or about to lose) something, or feel an urgent need to "break even" and fail to cut losses after a loss. Typical trigger signals: sunk cost trap, gambler's doubling down, irrational bidding in auctions, inability to abandon failed projects with heavy resource investment. Not applicable to general investment valuation (use value-assessment) or herd behavior (use misjudgment-checklist).
Produces a complete customer reactivation campaign for a client — a 4-part email and/or SMS sequence sent to a dormant customer list to generate immediate revenue within 48–72 hours. This is the single highest-ROI marketing activity available to most businesses: existing customers already trust the brand, require no new acquisition cost, and are statistically 5–9x more likely to buy than a cold prospect. The skill produces: the campaign strategy, all four email/SMS copy pieces, an optional referral offer embedded in the sequence, and a WhatsApp-adapted version for East African markets. Invoke when a client has an existing customer database and needs immediate revenue; when a client says "we've tried ads but they don't work"; or as the proof-of-value deliverable in a risk-free "first date" agency engagement before any retainer is agreed.
