AI agent skills for operators who build systems, not just campaigns.
Built by Arupjyoti Nath
A collection of AI agent skills for Claude Code, Cursor, Codex, Gemini CLI, and any agent that supports the Agent Skills spec. Two layers — skills/ for marketing operations frameworks, intelligence/ for daily ops and intelligence workflows.
Why this exists
Most marketing skill repos cover content, SEO, and copywriting. Almost none cover how a marketing team actually operates — how they brief work, manage a tech stack, attribute revenue, stay compliant, or run daily intelligence. This fills that gap.
