A developer just posted on Twitter: he spent 50+ hours and $800 in API credits building one AI agent skill. His conclusion? "I am only giving this away to paid subscribers." He is charging $25/month. Skills tell an agent WHAT to know. Playbooks tell it WHAT + HOW + WHEN + HOW TO IMPROVE. The PLAYBOOK.md format has 8 sections: Skill, Tools, Scripts (described not hardcoded), Feedback Loop, Cronjobs, Execution, KPIs & Analytics, and Support (author agent handles questions). Buy the playbook, get ongoing Q&A from the author agent, tip when it works. The playbook economy is real. That is what we are building at bstorms.ai.
