gncore 3.0.0

Universal AI Skill Installer for coding assistants.

GNCore

GNCore is a universal AI Skill Installer for coding assistants.

Install it once:

pip install gncore

Then activate the skills you want:

gncore activate

GNCore detects supported applications, installs the bundled skills into the right adapter-specific locations, writes prompt and command bundles, configures MCP where supported, verifies the installation, and stores a manifest so updates, validation, backup, and rollback are safe.

Supported applications

• VS Code Chat
• GitHub Copilot Chat
• Claude Desktop
• Claude Code
• Cursor
• Windsurf
• Continue.dev
• Gemini CLI
• OpenAI Codex CLI

Commands

gncore activate
gncore deactivate
gncore update
gncore doctor
gncore list
gncore install
gncore uninstall
gncore backup
gncore restore
gncore validate
gncore version

Quick start

pip install gncore
gncore list apps
gncore activate --apps cursor
gncore validate --apps cursor
gncore backup --output gncore-backup.zip

What GNCore installs

Each bundled skill includes:

• metadata
• description
• system prompt
• examples
• commands
• configuration
• version
• dependencies
• permissions

GNCore serializes those skills into application-compatible bundles through adapters. Every adapter has the same core contract, so adding a new application only requires a new adapter class.
