Installation

Using npx (Easiest)

One-command installation using the skills CLI (node must be installed).

npx skills add e-marchand/skills

Quick Install All

Run this command in your project directory:

curl -fsSL https://raw.githubusercontent.com/e-marchand/skills/main/install.sh | bash

Or specify a target directory:

curl -fsSL https://raw.githubusercontent.com/e-marchand/skills/main/install.sh | bash -s -- /path/to/your/project

Or install globally (available across all projects):

curl -fsSL https://raw.githubusercontent.com/e-marchand/skills/main/install.sh | bash -s -- --global

Or use symlink mode –symlink (copy to first folder, symlink the rest)

The installer will:

Detect existing .claude, .github, .agent or .codex folders (or their global equivalents with --global)
If none found, prompt you to choose which one to create
Download and install all skills to the appropriate location

Manual Installation

Copy the skill folders to the appropriate location for your AI assistant:

Assistant	Project Location	Global Location
Claude Code	`.claude/skills/`	Install from release
GitHub Copilot	`.github/skills/`	`~/.github/skills/`
Antigravity	`.agent/skills/`	`~/.gemini/antigravity/global_skills/`
Codex	`.codex/skills/`	`~/.codex/skills/`

Requirements

tool4d

Required by: 4d-check-syntax, 4d-find-command, 4d-form-screenshot. Also used by 4d-run when a dataless tool4d run is appropriate.

4D.app

Optional for: 4d-run and 4d-form-screenshot when the method needs a real database or runtime features not available in tool4d.

The skill can:

Use a user-provided 4D.app path
Use a user-provided 4D.exe path on Windows
Kill the launched process after a timeout if the startup method does not call QUIT 4D

Option 1: Install via Extension (Recommended)

Install the 4D-Analyser extension in VS Code or Antigravity. The extension will automatically install tool4d.

Option 2: Set Environment Variable

If you have tool4d installed elsewhere, set the TOOL4D environment variable to point to the tool4d executable:

export TOOL4D="/path/to/tool4d.app/Contents/MacOS/tool4d"

Add this to your ~/.zshrc or ~/.bash_profile to make it permanent.

Other Requirements

Python 3: Required by skills using Python scripts
macOS: Scripts are designed for macOS paths. Feel free to PR for other OS.

What are Agent Skills?
