The repository provides structured skills, prompts, and workflows that enable AI agents like Claude Code, Cursor, and Codex to perform marketing operations across four regions (Vietnam, US, EU, SEA, LATAM). It covers marketing strategy, content production, performance analytics, personal branding, and design across eight design types. The skills are aligned with Anthropic patterns and packaged for the Linh agent framework as a companion to the opa-kit system.
