Open-Source vs Exclusive Skills
Short answer: questflowai/investorskills is the free public layer — portable judgment systems you can run in Questflow or any agent that reads SKILL.md. Questflow exclusive skills are closed-source, labeled from real fund-manager trades (what they watched, why they entered, how they sized, what would invalidate). Public skills are for study and agent workflows. Exclusives are execution-grade distillation.
