CodeYak

Clean diffs. No surprises.

CodeYak is a Codex-powered VS Code extension for safe, controlled AI code changes with previews and instant reverts.

Features

• ✅ Explicit file selection - Choose exactly which files Codex can see
• ✅ Diff preview - Review all changes before accepting
• ✅ Accept/Reject buttons - One-click approval or rollback
• ✅ Task history - Track all Codex operations
• ✅ Git-backed safety - Automatic checkpoints and revert support
• ✅ No API keys - Uses Codex CLI (included with your plan)
• ✅ No token billing - Plan-based, not usage-based

Requirements

• Codex CLI installed (Install Codex)
• Signed into Codex (run codex auth login)
• ChatGPT Plus, Pro, Business, Edu, or Enterprise plan (Codex is included)

This extension does not use API keys or charge per token.

How It Works

1. Select files from your workspace tree
2. Enter a prompt describing what Codex should do
3. Run Codex - it reads only the selected files
4. Review the diff preview
5. Accept or Reject the changes

All changes are backed by Git checkpoints, so you can always revert safely.

Usage

1. Open the CodeYak sidebar (activity bar icon)
2. Select files from the workspace tree
3. Enter your prompt
4. Click Run Codex
5. Review the diff preview
6. Click Accept or Reject

Safety Features

• File size limits - Maximum 100KB per file
• File count limits - Maximum 10 files per task
• Git required - Automatic checkpoints before changes
• Manual approval - Codex runs with --approval=manual
• No repo-wide scans - Only selected files are sent

Why CodeYak?

Unlike other AI coding assistants, CodeYak:

• ❌ Never scans your entire repository
• ❌ Never uses API keys or token billing
• ❌ Never makes changes without explicit approval
• ✅ Gives you complete control over context
• ✅ Shows you exactly what will change
• ✅ Lets you revert instantly
