Create research-first masterclass guides for roles and disciplines. Use when the user asks for a masterclass, expert guide, role guide, or best-practices synthesis such as backend engineer, product manager, or technical writer. Research best-in-class voices first, then synthesize durable principles into a concise practical guide.
This skill turns a role, discipline, or narrowly scoped topic into a concise masterclass guide grounded in research rather than generic advice.
guides/ directory, write the result to guides/<topic>.md using kebab-case.
