Module 4 of 5Lesson 1 of 2~20 min

Iterate in small, checked steps

Asking a coding agent for ten changes at once is a good way to break everything. This lesson teaches you to evolve your app in small, controlled steps, review what the agent has changed and roll back with Git whenever a change does not work the way you wanted.

Lesson objective

By the end of this lesson, you will be able to evolve your app in short iterations (observe, describe, have it made, check, commit), review what the agent changed and go back to a previous version with Git.

Topics covered

  • iteration
  • Git
  • commit
  • rollback
  • coding agent

Where it fits

Iterate, debug and review

How do I evolve the tool without breaking it, and know whether it is ready to share?

Lessons in this module

  1. Iterate in small, checked steps (this lesson)
  2. Debug methodically and review before sharing

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.
