description	Use this skill when the user wants to generate secure short-lived GitHub tokens, set up Git credential helpers, or manage GitHub App authentication for local development.

Ghtkn Plugin

Generate short-lived (8-hour) GitHub App User Access Tokens for secure local development.

What is ghtkn?

ghtkn (GH-Token) generates secure 8-hour User Access Tokens from GitHub Apps using Device Flow. Stop risking token leaks with long-lived Personal Access Tokens.

Quick Start

# Initialize configuration
sc ghtkn init config

# Generate a token (opens browser for Device Flow)
sc ghtkn get token

# Use token with GitHub CLI
env GH_TOKEN=$(ghtkn get) gh issue create --title "Test"

# Use as Git credential helper
git config --global credential.helper '!ghtkn git-credential'

Key Features

• Short-lived tokens - Only 8 hours validity
• No secrets required - Only Client ID (not secret)
• User-attributed actions - Operations performed as you, not as app
• Automatic token management - OS keyring integration
• Multiple GitHub Apps - Switch apps by repository or directory

Key Commands

Configuration

• sc ghtkn init config - Create configuration file
• sc ghtkn list apps - List configured GitHub Apps

Token Management

• sc ghtkn get token - Generate/retrieve access token
• sc ghtkn get token --app myapp - Use specific GitHub App

Git Integration

• sc ghtkn git-credential helper - Use as Git credential helper

Setup

1. Create GitHub App with Device Flow enabled
2. Run ghtkn init config to create config file
3. Add Client ID to config: apps: - name: myapp client_id: xxx
4. Run ghtkn get token and authorize in browser

Configuration File

Location: ~/.config/ghtkn/ghtkn.yaml (Linux/macOS) or %APPDATA%\ghtkn\ghtkn.yaml (Windows)

    client_id: xxx
    git_owner: username  # Optional: switch by repository owner

Use Cases

• Secure local development with short-lived tokens
• Git authentication without long-lived PATs
• Multiple GitHub Apps for different organizations
• Automatic token rotation and management
• Directory-based app switching with direnv
