From Validated Idea to Replit Project

To turn a ShipFit playbook into a working Replit project, export your validated decisions as a Replit Agent brief, create a new Repl, paste the brief as the build prompt, and keep the spec in the project so it stays in context. Replit Agent then scaffolds your validated V1 (buyer, scope, pricing) and hosts it from the same workspace.

Before you start

You need a finished playbook. Run the full 9-decision flow first (a Quick Take takes about 2 minutes, the full playbook 15 to 20 minutes). The export only works once the prior 8 decisions are locked, because that is what fills the brief with real content: your buyer, your above-the-line pains, your V1 cut, and your pricing model.

You also need a Replit account. Replit Agent builds and hosts the project in the same workspace, so you can go from prompt to a live URL without leaving the editor.

Step by step

1. Finish the playbook and reach the export step. The export is the last of the 9 decisions. Pick Replit as a target (you can pick more than one tool at once). ShipFit packages your validated decisions into a brief written for Replit Agent.

2. Create a new Repl and open the Agent. Start with an empty workspace so the first scaffold is shaped by your validated scope, not by a template Replit picked on its own.

3. Paste the brief as the build prompt. Give Replit Agent the brief instead of a one-line idea. It covers your buyer, the V1 feature cut, the pricing model, and the cut features marked “do not build.” Agent plans and scaffolds against that scope rather than padding the app with everything it assumes a SaaS product needs.

4. Keep the spec in the project. Save the brief as a file in the Repl (e.g. a markdown doc in the root) so it stays alongside the code. When you ask Agent for changes later, point it back at that file so the validated context does not drift across sessions.

5. Smoke-test the context. Ask Agent: “Who is this product for and what is in V1?” If it answers with your validated buyer and your V1 scope rather than a generic guess, the brief took. If the answer is vague, the brief was trimmed or Agent never read it.

6. Build against the scope. When you ask for a feature, Agent already knows whether it is in V1 or parked. Ask “let’s add team billing,” and a well-scoped project should flag it if billing was cut. That is the point: the MVP scope decision survives into the workspace instead of dying in a doc.

Keeping it in sync

Re-run the export after any meaningful pivot, e.g. a new buyer segment or a changed pricing model. Replace the saved spec file with the fresh version and tell Agent to re-read it before the next change. A stale spec is worse than none, because Agent will confidently extend an app built around decisions you have already abandoned.

Because Replit hosts the project, you can share the live URL the moment V1 is standing, which is useful for the behavioral validation work the playbook sets up.

For the product-side detail on what the export contains and how Replit Agent consumes it, see the Replit integration page. This guide is the how-to; that page is the what-and-why.

Common mistakes

• Pasting a one-liner instead of the brief. Agent will happily build something, but it will be the most-likely SaaS app, not your validated one. The brief is what makes the output match your buyer and scope.

• Dropping the cut list. Without the “do not build” features, Agent adds settings panels, notification preferences, and dashboards because they are standard. Keep the cut list in the brief.

• Letting the spec go stale. If you pivot and do not re-export, Agent keeps building the old product. Re-export on every pivot and have Agent re-read the file.

• Treating Replit as the validator. Replit builds and hosts; it does not validate. The validation happens upstream in the playbook, where roughly 1 in 4 ideas gets killed before it reaches a builder. If you have not done that work, see pricing to start (the free tier includes 3 credits a month, paid playbooks from $5).
