How to Integrate & Use Skills in Your Projects

All skills in this directory follow the standard SKILL.md format with YAML frontmatter:

---
name: skill-name
description: Clear description of what the skill does and when the agent should trigger it.
---

Step 1: Clone the Repository

First, clone this repository locally:

git clone https://github.com/hamzabellouch/agent-skills.git

Step 2: Integrate Skills into Your Assistant

1. Google Antigravity, AGY CLI & Gemini CLI

• Project-Level (Specific Repository): Copy the desired skill folder or category into your project's .agents/skills/ directory:

  • Linux (Bash):

    mkdir -p /path/to/your-project/.agents/skills
    cp -r /path/to/agent-skills/Programming/Mobile/camerax /path/to/your-project/.agents/skills/
    

  • macOS (Zsh / Terminal):

    mkdir -p /path/to/your-project/.agents/skills
    cp -R /path/to/agent-skills/Programming/Mobile/camerax /path/to/your-project/.agents/skills/
    

  • Windows (PowerShell):

    New-Item -ItemType Directory -Path "C:\path\to\your-project\.agents\skills" -Force
    Copy-Item -Path "C:\path\to\agent-skills\Programming\Mobile\camerax" -Destination "C:\path\to\your-project\.agents\skills\" -Recurse
    

  • Windows (Command Prompt / CMD):

    mkdir "C:\path\to\your-project\.agents\skills"
    xcopy /E /I "C:\path\to\agent-skills\Programming\Mobile\camerax" "C:\path\to\your-project\.agents\skills\camerax"
    

• Global Level (All Projects): Copy skill folders to your global configuration directory:

  • Linux: ~/.gemini/config/skills/
  • macOS: ~/.gemini/config/skills/
  • Windows: %USERPROFILE%\.gemini\config\skills\

2. Claude Code (claude)

• Project-Level Integration: Copy desired skills into your project's .claude/skills/ folder:

  • Linux (Bash):

    mkdir -p /path/to/your-project/.claude/skills
    cp -r /path/to/agent-skills/Programming/Software_Engineering_Practices/* /path/to/your-project/.claude/skills/
    

  • macOS (Zsh / Terminal):

    mkdir -p /path/to/your-project/.claude/skills
    cp -R /path/to/agent-skills/Programming/Software_Engineering_Practices/* /path/to/your-project/.claude/skills/
    

  • Windows (PowerShell):

    New-Item -ItemType Directory -Path "C:\path\to\your-project\.claude\skills" -Force
    Copy-Item -Path "C:\path\to\agent-skills\Programming\Software_Engineering_Practices\*" -Destination "C:\path\to\your-project\.claude\skills\" -Recurse
    

  • Windows (Command Prompt / CMD):

    mkdir "C:\path\to\your-project\.claude\skills"
    xcopy /E /I "C:\path\to\agent-skills\Programming\Software_Engineering_Practices" "C:\path\to\your-project\.claude\skills"
    

• Plugin Directory Flag: Pass the skill category path directly when launching Claude Code:

  • Linux / macOS:

    claude --plugin-dir /path/to/agent-skills/Programming/Software_Engineering_Practices
    

  • Windows:

    claude --plugin-dir "C:\path\to\agent-skills\Programming\Software_Engineering_Practices"
    

3. Cursor IDE & Windsurf

1. Create a .cursor/skills/ directory inside your target project repository.
2. Copy your desired skill folders (e.g., camerax, test-driven-development) into .cursor/skills/.
3. Cursor will automatically parse SKILL.md manifests and invoke instructions when relevant.

4. Codex CLI (codex) & OpenCode

Copy the desired skill folders into your project's .codex/skills/ directory:

• Linux (Bash):

  mkdir -p /path/to/your-project/.codex/skills
  cp -r /path/to/agent-skills/Programming/Backend/Databases_and_Caching/* /path/to/your-project/.codex/skills/
  

• macOS (Zsh / Terminal):

  mkdir -p /path/to/your-project/.codex/skills
  cp -R /path/to/agent-skills/Programming/Backend/Databases_and_Caching/* /path/to/your-project/.codex/skills/
  

• Windows (PowerShell):

  New-Item -ItemType Directory -Path "C:\path\to\your-project\.codex\skills" -Force
  Copy-Item -Path "C:\path\to\agent-skills\Programming\Backend\Databases_and_Caching\*" -Destination "C:\path\to\your-project\.codex\skills\" -Recurse
  

• Windows (Command Prompt / CMD):

  mkdir "C:\path\to\your-project\.codex\skills"
  xcopy /E /I "C:\path\to\agent-skills\Programming\Backend\Databases_and_Caching" "C:\path\to\your-project\.codex\skills"
  

5. Cline, Roo Code & VS Code Agentic Extensions

• Workspace-Level Integration: Place the desired skills into .cline/skills/ or .roo/skills/ in your workspace root.
• Auto-Discovery: The agent will automatically read and index SKILL.md instructions into its active execution context when relevant tasks are triggered.

6. Desktop AI Apps (AionUi, Cherry Studio, LibreChat)

• Cherry Studio / AionUi: Settings -> Skills -> Add Local Skill -> Select any skill folder (containing SKILL.md).
• LibreChat: List local skill paths in your librechat.yaml under skills.local.

Best Practices

1. Context Window Efficiency: Copy only the relevant skill categories needed for your active project to keep prompt context focused and fast.
2. Standard Compatibility: Any AI coding assistant supporting the SKILL.md open specification will automatically detect skill descriptions and execute instructions seamlessly.
