nococli

Your code is yours. Your commits should be too.

AI tools (Claude Code, Copilot, Cursor) auto-add themselves as co-author on every commit.

But you wrote the code. You understand it. You're responsible.

One command to reclaim ownership:

npx nococli

That's it.

How It Works

nococli installs a Git commit-msg hook that automatically strips AI co-author signatures from your commit messages before they're saved. The hook is installed globally via git init.templatedir, so it applies to all new repositories automatically.

On Windows, nococli installs a PowerShell-native hook runtime with a Git hook wrapper entrypoint so commits work from PowerShell 5.1 and PowerShell 7+.

For existing repositories, just run git init to pick up the hook.

CLI Commands

# Install hook globally (default when running npx nococli)
npx nococli
npx nococli install           # Same as above
npx nococli install --force   # Overwrite existing hook without prompting

# Check installation status
npx nococli status

# List all AI signature patterns being removed
npx nococli patterns

# Change git author if current author looks like an AI
npx nococli setup-author

# Remove hook from your system
npx nococli uninstall
npx nococli uninstall --remove-config  # Also remove git template config

Supported AI Signatures

Removes co-author signatures from:

• Claude (Claude Code, Claude Sonnet, Claude Opus, etc.)
• GitHub Copilot
• ChatGPT / OpenAI (GPT-4, ChatGPT-4o, etc.)
• Cursor AI
• Tabnine
• Amazon CodeWhisperer
• Codeium
• Replit Ghostwriter
• Sourcegraph Cody
• Factory Droid
• Google Gemini (Gemini Pro, Gemini 1.5, etc.)
• Perplexity AI
• Amazon Q
• Amp AI

Pattern Matching

• Case-insensitive — Co-Authored-By, co-authored-by, CO-AUTHORED-BY all matched
• Flexible whitespace — spaces, tabs, no space after colon
• Version numbers — Claude 3.5 Sonnet, GPT-4, etc.
• Email-domain matching — catches AI signatures by email regardless of name

Features

• Zero-config — one command to install, works everywhere
• Lightweight — single runtime dependency (commander), ~85KB bundle
• Windows PowerShell-native support — works with PowerShell 5.1 and 7+ on Git for Windows
• AI author detection — warns if your git author name looks AI-generated and helps you fix it
• Preserves human co-authors — only strips AI signatures, keeps real collaborators
• Works with all git workflows — rebase, amend, merge, interactive rebase

Requirements

• Node.js >= 18.0.0
• Unix/Linux/macOS: Git with standard hook support
• Windows: Git for Windows plus PowerShell 5.1 or PowerShell 7+

Install

# Run directly with npx (recommended)
npx nococli

# Or install globally
npm install -g nococli
noco
