Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.
$ npx skills add coreyhaines31/marketingskills --skill reverse-engineer-marketingNeeds Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.
Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /reverse-engineer-marketing.
It includes scripts that Claude may run on your computer, so skim them on GitHub before you install.
