Prerequisites
2of 8~5 min
- How to verify your coding agent is installed and working
- The difference between Claude Code and Codex
- How to check your subscription tier
What you'll do
- Select your preferred coding agent (Claude Code or Codex)
- Verify installation with a test command
- Confirm you have the required subscription tier
Choose Your Coding Agent
This tutorial works with either Claude Code or Codex. Select the one you have:
Requirements
- Claude Max subscription ($100/month or usage-based)
- Node.js 18+ installed
- Terminal access
1. Install Claude Code
If you haven't already, install Claude Code globally:
Terminal
2. Verify Installation
Check that Claude Code is installed and accessible:
Terminal
You should see output like: claude-code v1.x.x
3. Authenticate
Log in to your Anthropic account:
Terminal
This will open a browser window for authentication. Ensure you're logging in with an account that has Claude Max.
4. Quick Test
Verify everything works with a simple test:
Terminal
You should see a response mentioning Opus 4.5 (or similar). If you see an error about rate limits or authentication, check your subscription.
Warning
If your test command returns an authentication or subscription error, you'll need to resolve that before continuing. Both Claude Max and GPT Pro are paid subscriptions — free tiers won't work for the coding agent features we need.
Pro Tip
Remember which tool you chose! The rest of the tutorial will reference your selected agent. You can always come back here to switch if needed.
Next up: In Step 3, you'll clone the BrennerBot repository and give your agent access to the codebase.
