You're in

Get kitstarter running in two minutes.

Thanks for buying the kit. Everything below installs it and makes your agent ask first, build lean, and stop looking AI-made. It works in Claude Code, Codex, and Antigravity.

Install

One command, in any project. You just need Node 18+ and Claude Code.

# in your project — installs the core
npx kitstarter-cli

# everything: design tools, the 37-tell detector, extra skills, hooks, voices
npx kitstarter-cli --full

# globally, for every project at once
npx kitstarter-cli -g --full

It asks for the email you bought with to confirm your purchase, then installs. After that, open Claude Code and run /tour to get set up.

Used a different email? Re-run and enter the email on your Stripe receipt. Prefer a reusable command? Install the CLI once with npm install -g kitstarter-cli, then run kitstarter init -g (global) or kitstarter init (this project only).

What you installed

The core is always on: a single rule in AGENTS.md that makes the agent ask before it builds and be direct, plus /start, /tour, and a session greeting.

--full adds the rest: the build skills (/step, /check, /fix, /review, /lean), loop engineering (/loop, /iterate), ship & survive (/ship, /secrets, /recover, /explain), the anti-slop detector (/design-intake, /design-check, /polish), reach (/connect-mcp, /claude-tips), and the voices.

Pick a voice

The default voice is direct. To switch how the agent explains itself, run /output-style in Claude Code and choose one:

Teaching — explains the why as it goes, so you learn the foundations.
Simple — plain and minimal, just what to do next.
Technical — precise and architectural.

Everyday use

New thing to build → /start (it asks the right questions first).
New screen or UI → /design-intake, then /design-check before you ship.
Not sure what the kit does → /tour.

You don't have to memorize commands. The core habit runs on its own: the agent asks before it acts, builds the smallest thing that works, and proves it runs before calling it done.

Updating

Your purchase includes lifetime updates. To get the latest, run the installer again with @latest. Re-running is safe and idempotent, so nothing breaks.

npx kitstarter-cli@latest -g --full

Works with

Claude Code — everything: the rule, skills, hooks, and voices.
Codex & Antigravity — the ask-first rule travels through AGENTS.md, so the core habit works there today; skills and hooks are Claude Code for now.

Troubleshooting

"No purchase found for that email." Enter the exact email on your Stripe receipt. Still stuck? Reply to the receipt and we'll sort it out.
Need Node. The installer runs on Node 18+. Check with node --version.
Already have an AGENTS.md? The installer won't overwrite it; merge in the one rule from the kit's AGENTS.md.
Hooks not firing? Re-run npx kitstarter-cli --full, then restart Claude Code so it reloads settings.json.
Start over. Re-running the installer is safe and idempotent.
