Pstack for Claude Code: How a React Core Engineer Ships Code With AI

pstack is the open-source skill pack Lauren Tan (React core team) uses every day at Cursor, and since October 16 it installs in Claude Code. I mapped all of it onto the six stages of shipping software (plan, design, build, test, ship, maintain), with which skill fires where, what changes in Claude Code, what it really costs in tokens, and the three ideas I'm taking into my own setup.
