What problem does it solve? Creating believable, specific persona agents for product review or conversational use is hard — generic persona descriptions produce generic feedback. This Skill guides the structured authoring of character-based agent files written to ~/.claude/agents/. ## Core Features & Use Cases - Persona Authoring Workflow: A nine-step process covering character definition, evaluation criteria, voice calibration, response format, constraints, and tool access. - Two Persona Types: Supports review personas (stakeholders evaluating copy, design, or messaging) and conversational personas (named characters interacting with users directly). - Use Case: A product manager wants to test whether landing-page copy resonates with a target-market parent. The Skill produces a fully specified persona agent file (e.g., persona-theresa.md) that reviews the copy in character and returns structured takeaways. ## Quick Start Ask the agent to author a review persona named Theresa, a 50-year-old parent, who evaluates a therapist's website copy for a pre-launch product.
