AI Tools Setup

OpenCode is an open source AI coding assistant that helps you write, understand, and modify code. Think of it as an AI pair programmer that runs in your terminal.

You already installed OpenCode in Module 1. Now you will configure it and connect it to an AI provider.

Configure a Provider

OpenCode needs an LLM provider to work. You have several options:

1. OpenCode Zen (recommended) -- curated models, no API key hassle
2. Any provider -- Anthropic, OpenAI, Google, GitHub Copilot, and 75+ more

To connect a provider:

1. Run opencode to start the TUI
2. Type /connect and select your provider
3. Follow the login instructions

Alternatively, set up an API key in your environment:

# Anthropic
export ANTHROPIC_API_KEY=sk-ant-...

# OpenAI
export OPENAI_API_KEY=sk-...

# Or use a .env file in your project

Initialize OpenCode

Navigate to your project and start OpenCode:

cd /path/to/your/robot-code
opencode

Then run the /init command:

/init

This tells OpenCode to analyze your project and create an AGENTS.md file in your project root. This file helps OpenCode understand your project structure and coding patterns.

Commit your AGENTS.md to Git -- it helps OpenCode provide better results every time.

Verify It Works

Ask OpenCode something simple:

What does this project do?

If it responds with a description of your project, you are ready to go.

Troubleshooting

Problem	Solution
Command not found	Reinstall or check your PATH
API key errors	Run /connect or set environment variable
Model not responding	Try a different model with /model
Slow responses	Use a smaller/faster model

Quiz

Q1: What does /init do in OpenCode?

• [ ] A) Deletes your project
• [ ] B) Creates an AGENTS.md file with project context
• [ ] C) Installs OpenCode
• [ ] D) Pushes code to GitHub

Answer

B) Creates an AGENTS.md file with project context

The /init command analyzes your project and creates an AGENTS.md file that helps OpenCode understand your codebase.

Q2: How do you connect an AI provider in OpenCode?

• [ ] A) Edit a JSON config file
• [ ] B) Type /connect in the TUI
• [ ] C) Reinstall OpenCode
• [ ] D) Providers are pre-configured

Answer

B) Type /connect in the TUI

The /connect command lets you select and sign in to an AI provider directly from the terminal.

Q3: What should you do with the AGENTS.md file after /init creates it?

• [ ] A) Delete it
• [ ] B) Add it to .gitignore
• [ ] C) Commit it to Git
• [ ] D) Ignore it
