syntax-syndicate/marketing-skills ? reverse-engineered prompt

Build me a collection of AI agent marketing skills that I can drop into a project and use with Claude Code, Cursor, Codex, and other agent tools.

I want the skills to help with things like conversion optimization, copywriting, SEO, analytics, paid growth, customer research, and launch strategy. Each skill should be its own clear markdown guide, and they should all share a common product and marketing context so the agent can make better decisions before it writes copy or suggests changes.

Make it easy to browse the skills, keep the structure consistent, and include a way to validate that everything is set up correctly. If there are any best practices for the Agent Skills format, use those. If you need to check current docs online, go ahead and do that. The end result should feel polished and ready for a marketer or founder to use right away.
