What Composure actually is, in one paragraph.

An add-on for Claude — the AI you already build with — that gives it the complete rulebook for how real apps get built, then enforces it. The rules aren't something your AI could read. They're something it can't skip.

Who it's for

You're building a multi-tenant SaaS with an AI coding agent doing real implementation work.
You've either been burned once (a permission bug, a secret in a bundle, a silent regression) or you've read about someone who was, and you'd rather not find out the hard way.
You want your agent to stop re-deriving the same architectural decisions every session.

The first 10 minutes

Three commands. What actually happens after each one.

Install Composure

bash

$pnpm dlx create-composure

Free tier, no credit card. Same command as the homepage — this page is the fuller walkthrough, not a different path.

Initialize your project

bash

$/composure:initialize

Detects your stack and generates config. This is also where GitHub CODEOWNERS gets set up — unasked. See /why/questions-you-didnt-ask.

Run your first audit

bash

$/composure:audit

Watch your agent cite the governing pattern before it starts building — the classifier at work in your own session, no prompting needed.

Ten minutes. Free. No card.
