gstack

gstack is Y Combinator's president sharing his exact Claude Code setup — and 45K developers took notice. Fifteen slash commands that simulate a virtual engineering team: a CEO who rethinks the product, a designer who catches AI slop, a paranoid reviewer who finds production bugs, a QA lead who opens a real browser and clicks through your app. It's one person's workflow, made universal.

If you're a solo founder shipping a product with Claude Code, gstack is the fastest way to go from "me and an AI" to "me and a team of AI specialists." The opinionated structure forces good practices — design review before shipping, QA before deploying, architecture review before building. Alternatives: custom CLAUDE.md files are more flexible but require writing your own. Awesome Codex Subagents has more agents but less curation. Cursor's built-in workflows are the commercial equivalent.

The catch: one person's workflow is one person's preferences. Garry Tan builds YC-style products — if your stack, pace, or taste diverges significantly, the opinions become friction, not guidance. At 45K stars it's arguably over-hyped relative to what it actually is: fifteen markdown files. And celebrity open-source projects sometimes get stars for the name, not the substance.
