# Port the prototype into code

**A method by Alexis Boyer · version 4.0 · September 22, 2026**

**Gate 4.** Hand the prototype and the starter to the coding agent, and keep it inside your organization's conventions. It is quoted here exactly as it appears in [the core guide](/fr/resources/method-guide).

## The text to copy

```text
You are at Gate 4 of the method: porting the prototype into code.
You are implementing [PRODUCT / SLICE].

Read before coding:
- the prototype from Gate 3, in the form it was handed to you
- the PRD, whose first section is the strategic framing
- the approved frontend starter repository and its conventions
- the backend conventions
- the project memory and journal

Product boundary:
[WHO THE PRODUCT IS FOR, WHO IT IS NOT FOR, AND WHAT MUST NOT BE BUILT HERE]

Rules:
- the prototype is the visual and product reference;
- the starter repository and its conventions decide how the code is written;
- do not paste the design tool's export into the application foundation;
- keep routes thin;
- put domain logic in feature folders;
- use the organization's shared primitives before creating anything new;
- route mock data through API-shaped services that match the future backend contracts;
- centralize copy and localization;
- enforce role and privacy rules at the read-model level;
- do not redesign anything unless you are explicitly asked to;
- before each change to the code, re-read the starter's rules and the backend conventions.

Current task:
[THE FLOW, SCREEN OR FIX]

Acceptance criteria:
- the flow works end to end in the front-end mock;
- the result matches the design where the design is non-negotiable;
- no privacy regression;
- relevant tests added or updated;
- project memory and journal updated if this changed product behavior, architecture, a stakeholder decision or future reasoning.

Run before finishing:
- typecheck
- lint
- tests
- build
- click through the flow in a browser

Report:
- which gate you are at, what you have, what is missing, and what I must
  decide before you cross
- what changed
- what you actually ran and what it returned
- memory and journal updates made, or explicitly skipped with the reason
- remaining open product or backend decisions
