Module 3 of 5Lesson 2 of 3~18 min

From framing to plan, then to code

A coding agent produces far better results when it plans before it writes. This lesson teaches you to write a structured build request, review and approve the proposed plan before any code is written, then get a first version running on your own machine so you can try it right away.

Lesson objective

By the end of this lesson, you will be able to write a five-block build request for a coding agent, get a plan approved in plan mode before any code is written, and obtain a first version running locally.

Topics covered

  • prompting a coding agent
  • plan mode
  • Claude Code
  • first version

Where it fits

Set up your machine and generate the first version

How do I get a first version running on my machine, and understand what was created?

Lessons in this module

  1. Set up your workstation
  2. From framing to plan, then to code (this lesson)
  3. Understand what the agent built

What you will learn in the course

This lesson is part of the course Build and ship a web app with an AI coding agent

  • Frame a tool (problem, user, inputs, expected result) and write its acceptance criteria before generating a single line of code.
  • Choose between a chat with artifacts, an app builder and a coding agent based on the need, the level of control required and the risk.
  • Write a build request for a coding agent (context, scope, constraints, verification) and get a plan approved before any code is written.
  • Set up the environment (terminal, Node.js, Git, Claude Code), run the application locally and explain what the main files of the generated project are for.
  • Evolve and debug the application in small, checked, committed iterations, giving the agent the right context (symptom, steps, error message).
  • Review the generated app before sharing it (behavior, edge cases, secrets, personal data, experience) and decide whether to ship, fix or stop.
  • Publish the app from GitHub to a host with continuous deployment, get a public URL and evolve the live version without breaking it.
