How to Install Skills for Claude Code, Gemini CLI, Cursor, and OpenCode

Use the npx antigravity-awesome-skills installer with tool-specific flags to automatically deploy 1,265+ reusable skills to the correct directories for each AI coding assistant.

The sickn33/antigravity-awesome-skills repository provides a universal library of markdown-based skills that extend AI agents with concrete, repeatable actions. Each skill follows a standardized SKILL.md format, allowing the same files to work across Claude Code, Gemini CLI, Cursor, and OpenCode without modification.

What Are Antigravity Awesome Skills?

Antigravity Awesome Skills is a curated collection of 1,265+ skill definitions stored in the skills/ directory. Each skill resides in its own folder containing a SKILL.md file that defines metadata, trigger patterns, and execution steps. The repository ships with a Node-based installer located at tools/bin/install.js that handles platform detection, safe file copying, and directory resolution.

Installing Skills for Claude Code

Claude Code supports two installation methods: direct CLI installation via NPM or one-click installation through the Claude Code plugin marketplace.

Method 1: NPM Installer

Run the installer with the --claude flag to copy all skills to ~/.claude/skills/:

npx antigravity-awesome-skills --claude

Verify the installation:

test -d ~/.claude/skills && echo "✅ Claude Code skills installed"

Method 2: Plugin Marketplace

Claude Code can read the manifest files in .claude-plugin/plugin.json and .claude-plugin/marketplace.json to perform a one-click install:

/plugin marketplace add sickn33/antigravity-awesome-skills
/plugin install antigravity-awesome-skills

The marketplace flow performs the same copy operation as the CLI installer, placing skills in .claude/skills/ based on the repository's plugin configuration.

Installing Skills for Gemini CLI

For Google's Gemini CLI, use the --gemini flag to target the ~/.gemini/skills/ directory:

npx antigravity-awesome-skills --gemini

Confirm the skills are available:

test -d ~/.gemini/skills && echo "✅ Gemini CLI skills ready"

Installing Skills for Cursor

Cursor loads skills from a workspace-relative .cursor/skills/ folder. Run the installer from your project root with the --cursor flag:

npx antigravity-awesome-skills --cursor

This creates a .cursor/skills/ directory in your current working directory, which Cursor automatically detects and loads when you open the workspace.

Installing Skills for OpenCode

OpenCode uses the generic .agents/skills/ path. Because OpenCode does not have a dedicated CLI flag, specify the target directory using the --path option:

npx antigravity-awesome-skills --path .agents/skills

Verify the installation:

test -d .agents/skills && echo "✅ OpenCode skills installed"

How the Installer Works

The installation logic resides in tools/bin/install.js. This Node-based script performs three core operations:

1. Platform Detection: Parses CLI flags (--claude, --gemini, --cursor, --path) to determine the target directory (e.g., ~/.claude/skills/, ~/.gemini/skills/, .cursor/skills/, or a custom path).

2. Safe File Copying: Recursively copies every SKILL.md file and associated assets from the skills/ directory to the resolved destination. The script sanitizes symlinks during copying to prevent directory traversal attacks.

3. Directory Resolution: Handles both global paths (for Claude Code and Gemini CLI) and workspace-relative paths (for Cursor and OpenCode) based on the tool's expected conventions.

The package.json at the repository root exposes the CLI entry point, enabling the npx command to execute tools/bin/install.js without global installation.

Using Installed Skills

Once installed, invoke any skill using the @skill-name syntax within your AI assistant's chat interface. For example, in Claude Code:

>> Use @brainstorming to help me design a todo-list web app

The AI loads brainstorming from ~/.claude/skills/brainstorming/SKILL.md (or the equivalent path for other tools) and guides you through the structured action defined in that file.

Summary

• One installer, multiple tools: The npx antigravity-awesome-skills command supports Claude Code, Gemini CLI, Cursor, and OpenCode through specific flags.
• Automatic path detection: The installer places skills in ~/.claude/skills/, ~/.gemini/skills/, .cursor/skills/, or .agents/skills/ based on the target tool.
• Claude Code marketplace support: Install via /plugin marketplace add sickn33/antigravity-awesome-skills using the manifests in .claude-plugin/.
• Universal format: All 1,265+ skills in the skills/ directory work across every supported platform without modification.

Frequently Asked Questions

How do I update skills after the initial installation?

Re-run the same installation command used for your specific tool. The installer in tools/bin/install.js overwrites existing files with the latest versions from the skills/ directory. For Claude Code, you can also use /plugin update antigravity-awesome-skills if installed via the marketplace.

Can I install skills for multiple tools simultaneously?

Yes. The installer is stateless and targets specific directories based on flags. You can run npx antigravity-awesome-skills --claude followed by npx antigravity-awesome-skills --gemini to populate both global directories. Each command operates independently on the same source files in skills/.

Why does OpenCode use --path instead of a dedicated flag?

OpenCode follows the generic .agents/skills/ convention rather than a tool-specific directory name. Because the installer cannot assume a fixed path for OpenCode (users might customize their agents directory), it requires the explicit --path .agents/skills argument to resolve the destination correctly, as noted in the repository's README installation section.

Are the skill files modified during installation?

No. The installer performs a safe copy operation that preserves the original content of each SKILL.md file. The script in tools/bin/install.js sanitizes symlinks for security but does not alter the skill definitions themselves, ensuring consistent behavior across Claude Code, Gemini CLI, Cursor, and OpenCode.
