A Claude setup for solo founders

plsBuild OS turns it into a system.

A kit of 18 skills, one profile template, and the instructions I wish someone had handed me on day one.

See the difference. 60 seconds.

Why I made this
"Every new session, I was re-explaining myself to Claude. The output was only as good as the setup."

After nine years in corporate roles, I forgot I could just make things alone. Claude brought that back — but only once I stopped using it like a chatbot and set it up like a system. plsBuild OS is the setup layer I built for myself.

PROJECT-SPECIFIC CONTENT

Everything a product needs, in one folder.

Every product you build gets its own workspace. A brief Claude reads at session start, a living spec you update at session end, skills that only apply to this product, and specialized agents for reviews. Shared stays shared. Project stays project.
