What problem does it solve? Building personas often produces fictional biographies or unsupported claims. This Skill structures persona research so every claim is classified as observed evidence, synthesis, or hypothesis, with preserved source metadata and explicit uncertainty. ## Core Features & Use Cases - Evidence-graded research: Separates observed evidence, synthesis, and hypotheses, and preserves publisher, URL, dates, and population context for every source. - Structured persona modeling: Keeps workflows, activities, skills, and tool candidates distinct, with tiers, friction, success signals, and confidence levels. - Controlled updates: Classifies new sources as confirms, extends, qualifies, or contradicts, and requires explicit authorization before any live record change. - Use Case: A product manager researching a new user role can produce a record-shaped persona proposal with an evidence table, workflow map, tool hypotheses, and a validation plan—without mutating any library data. ## Quick Start Use $persona-research to research this role with explicit evidence and uncertainty.
