What problem does it solve? Recruiting the wrong participants ruins a study before it starts: screeners that telegraph the study topic attract impostors, demographic proxies miss real target users, and professional participants slip through undetected. This Skill turns a participant profile into a screener that finds genuine target users while concealing the study's purpose. ## Core Features & Use Cases - Behavioral criteria translation: Converts demographic proxies into verifiable past behaviors with recency windows, one criterion per question. - Intent masking and red-flag traps: Builds select-all questions with plausible distractors, exclusion-first ordering, consistency traps, and professional-participant detection rules. - Full recruiting plan: Delivers per-question accept/reject/quota logic plus channel selection with bias flags, incentive calibration, and over-recruit buffers (20% moderated, 30-50% unmoderated). - Use Case: You have a usability test plan calling for 5 participants who book personal-care appointments. Use this Skill to produce a masked screener with knockout logic, a quota split between online and phone bookers, and a recruiting plan with channel, incentive, and no-show buffer. ## Quick Start Write a participant screener and recruiting plan for my study using the participant profile and sample size from my research plan.
