First-party only — a session id and where you arrived from, so we can tell which pages are worth writing more of. No advertising, no third-party trackers, nothing that follows you off this site.
What you actually receive, how you get to it, and what happens afterwards.
The Foundations track is nine lessons, open to everyone, no account and no email required. It covers the ground everything else builds on: what changes when you work with an agent, writing a memory file, scoping a request, reading a diff you did not write, and reproducing a bug before diagnosing it.
If that writing is not useful to you, nothing else here will be either, and you have lost nothing finding that out.
Every pack page lists every file it contains, with a description of each. Several files in each pack are marked readable and can be opened in full, right now, without an account. Nothing is hidden until after you pay.
You enter your email and receive a six-digit code. That is the entire account creation process — there is no password to choose, and signing in later works the same way. The account exists so a purchase can be attached to something that does not get lost when you clear your cookies.
Payment is handled by Stripe. We never see your card details. The charge appears on your statement with PAIRFOUNDRY in the description.
Access is immediate — the unlock happens while you are still on the confirmation page, not when some background job catches up. Then you can:
The tools change constantly. When a change makes a file in a pack wrong, we fix it and the fix is in your library — free, permanently, no version 2 to buy. Each pack page shows its current version and when it was last updated.
It is not a course, a video series, a community, or a Discord. It is a folder of text files. If you want to be taught rather than handed something, the free track is the better use of your time.
And none of it removes the need to read your own diffs. Every prompt in every pack narrows where you look. None of them replaces looking.
A pack you buy is yours permanently, including updates, even if you never pay us again. Membership gets you everything — all packs, all tutorial tracks, plus whatever is published while you are a member — and access ends when the membership does. The pricing page compares them honestly, including where each one is the worse choice.
14 days on everything, no explanation required. One line by email and we refund it. See the refund policy.
