How to Set Up an AI Coding Agent

An AI coding agent is an autonomous AI that can write, execute, and iterate on code without constant hand-holding. Unlike chat-based assistants where you copy-paste code back and forth, an agent has direct access to your filesystem, terminal, and development tools. It can create files, run tests, fix errors, and keep going until the job is done.

Zo Computer gives you this out of the box. Your AI has root access to a real Linux server with a full development environment—Node.js, Python, git, and whatever else you need. When you ask it to build something, it actually builds it.

What makes a coding agent different

Traditional AI coding assistants are glorified autocomplete. You prompt, they respond, you copy-paste, you debug, you prompt again. The feedback loop is slow and manual.

A coding agent closes that loop. It can:

  • Write code directly to files

  • Run the code and see the output

  • Read error messages and fix them

  • Install dependencies

  • Create entire project structures

  • Test its own work

This turns "help me write a function" into "build me a working CLI tool." The AI does the grunt work while you focus on what you actually want to build.

Getting started

On Zo, your AI is already a coding agent. There's no setup required—just describe what you want:

Build a TypeScript CLI that fetches my GitHub notifications and displays them in the terminal

The AI will:

  1. Create the project files

  2. Write the code

  3. Handle authentication

  4. Test it and fix any issues

  5. Give you a working tool

You can watch it work in real-time, and jump in to redirect if needed.

Example: Building a web scraper

Let's walk through a real example. Say you want to scrape product prices from a website:

Create a web scraper that extracts product names and prices from https://example-store.com/products and saves them to a CSV

The agent will:

  1. Analyze the target — Fetch the page and inspect its HTML structure

  2. Choose the right tools — Decide between simple fetch + cheerio or a headless browser

  3. Write the scraper — Create a script that extracts the data

  4. Test it — Run the script and verify the output

  5. Handle edge cases — Deal with pagination, rate limiting, or dynamic content

  6. Save the results — Write to CSV in your workspace

If the first approach doesn't work (maybe the site uses JavaScript rendering), the agent will recognize the failure and try a different approach—like switching to Puppeteer or Playwright.

Tips for better results

Be specific about what you want. "Build me a website" is too vague. "Build a landing page for a coffee shop with a menu section and contact form" gives the agent a clear target.

Let it run. The agent often needs several iterations to get things right. Don't interrupt too early—let it hit errors and fix them. That's how it learns what works.

Point it to examples. If you have a coding style or existing codebase, mention it: "Follow the patterns in my existing API routes" or "Use the same structure as project X."

Ask for tests. "Write tests for this" helps the agent verify its own work. Good tests catch bugs before you do.

When to use a coding agent

Coding agents excel at:

  • Boilerplate — Generating project scaffolding, config files, CI pipelines

  • Automation scripts — One-off scripts for data processing, file manipulation, API calls

  • Prototypes — Getting a working version fast, then refining manually

  • Refactoring — Applying consistent changes across many files

  • Learning — Seeing how to implement something you haven't done before

They're less suited for:

  • Architecture decisions (they'll happily build the wrong thing if you let them)

  • Performance-critical code that needs careful optimization

  • Security-sensitive code that needs expert review

Going further

Once you have a coding agent workflow, you can extend it:

  • Connect your IDE — Use VS Code Remote-SSH to edit files while the agent works alongside you

  • Set up CI — Let the agent create GitHub Actions for automated testing

  • Build tools — Have the agent create CLI tools that automate your common tasks

The goal isn't to replace programming—it's to automate the tedious parts so you can focus on the interesting problems.
