One founder's handbook for running a company on Claude Code: the skills I install, the setups I copied, the rules I keep, and the people worth learning from. It is not a directory of everything that exists - if something is here, it earned its place in real work. Suggest a link by opening an issue (see CONTRIBUTING.md).
Descriptions are my own notes where I wrote one. Where I only saved a link, the description is the repository's or the post's own summary. Ratings like (Matt: 8/10) are my personal scores.
