root-cause-framing
by tonyflo79
Identify and frame the root cause behind the audience's surface-level problem. Use after research (Skill 01) is complete and you need to define the deeper problem that the product solves — the hidden cause behind the symptoms the audience experiences. Produces the root cause package with core problem identification, villain framing, and reframe narrative. The root cause is the foundation of persuasion — without it, copy addresses symptoms instead of the real issue. Trigger when users mention root cause, underlying problem, real reason, villain identification, problem framing, or why conventional solutions fail. Requires research handoff from Skill 01.
