§ 01 · The package

What you actually receive when you buy.

Not a slide deck. Not a Notion template. A working product repo with a Stripe checkout already firing on the same domain you’re reading this on.

§ 02 · Agentic workflow

Built so an agent can niche this repo into your product.

The hardest part of agentic codebases is telling the agent what it must not break. We wrote those rules for you. The result: an agent can rewrite the product surface in an afternoon without touching billing, auth, or the citation contract.

01step

Clone & open with your agent

Hand the private repo to Codex or Claude. AGENTS.md tells them which boundaries are sacred and which surfaces to rewrite.

> git clone toolbound-stack my-product
> open AGENTS.md
> /agent: re-skin the Document Q&A workflow
       as an HR Policy Assistant for UK SMEs.

02step

Niche the product down

The agent rewrites copy, prompts, dashboard examples, and pricing tiers without touching billing, auth, or citation contracts.

✓ updated  src/lib/template-data.ts
✓ updated  src/lib/ai/document-qa.ts
✓ updated  src/app/page.tsx hero copy
✓ kept     src/lib/sales/* untouched
✓ kept     src/lib/usage.ts contract

03step

Verify & ship

Run the bundled verify script. Tests, lint, and build gate every change so an agent run cannot quietly break the product.

> npm run verify
  setup-check  ok
  vitest       42 passed
  eslint       clean
  next build   compiled in 14.2s
ready ▌

§ 03 · Live demo

A note on the example subscription plans

The Starter / Pro / Agency tiers you see inside the demo app are example pricing the generated SaaS uses for its own subscribers. They are wired through the code so you can edit them in one place when you launch your own product. The fee above is what you pay us for the repo.
