Agent OS transforms AI coding agents from confused interns into productive developers. With structured workflows that capture your standards, your stack, and the unique details of your codebase, Agent OS gives your agents the specs they need to ship quality code on the first try—not the fifth.

Use it with:

✅ Claude Code, Cursor, or any other AI coding tool.

✅ New products or established codebases.

✅ Big features, small fixes, or anything in between.

✅ Any language or framework.

• Windows PowerShell 5.1 or later (or PowerShell 7+)
• Internet connection for downloading files

Open PowerShell as Administrator and run the following one-liner to install Agent OS:

Invoke-Expression (Invoke-WebRequest -Uri "https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup.ps1" -UseBasicParsing).Content

What this does:

• Creates ~/.agent-os/ directory structure in your user profile
• Downloads your development standards files
• Downloads Agent OS instruction files
• Sets up the foundation for AI coding agents

Optional flags:

# Overwrite existing instruction files
Invoke-Expression "& { $(Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup.ps1' -UseBasicParsing).Content } -OverwriteInstructions"

# Overwrite existing standards files  
Invoke-Expression "& { $(Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup.ps1' -UseBasicParsing).Content } -OverwriteStandards"

⚠️ Important: After installation, customize the standards files in %USERPROFILE%\.agent-os\standards\ to match your preferences:

• tech-stack.md - Your default frameworks, libraries, and tools
• code-style.md - Your formatting rules and naming conventions
• best-practices.md - Your development philosophy and patterns

Choose your AI coding tool:

Invoke-Expression (Invoke-WebRequest -Uri "https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup-claude-code.ps1" -UseBasicParsing).Content

Then use these commands in Claude Code:

• /plan-product - Initialize a new product
• /analyze-product - Add Agent OS to existing codebase
• /create-spec - Plan a new feature
• /execute-tasks - Build and ship code

Navigate to your project root directory in PowerShell, then run:

Invoke-Expression (Invoke-WebRequest -Uri "https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup-cursor.ps1" -UseBasicParsing).Content

Then use these commands in Cursor:

• @plan-product - Initialize a new product
• @analyze-product - Add Agent OS to existing codebase
• @create-spec - Plan a new feature
• @execute-tasks - Build and ship code

Invoke-Expression (Invoke-WebRequest -Uri "https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup-vscode.ps1" -UseBasicParsing).Content

The script will ask you:

1. VS Code version: Choose between VS Code (stable) or VS Code Insiders
2. File prefix: Optional prefix for organizing files (e.g., 'g-', 'u-', 'agent-')

This creates prompt and instruction files in your VS Code user directory:

• Commands → Prompts: plan-product.prompt.md, create-spec.prompt.md, etc.
• Standards → Instructions: tech-stack.instructions.md, code-style.instructions.md, etc.

Then use these files in VS Code:

• Press Ctrl+Shift+P and search for "Prompts"
• Select your Agent OS prompts and instructions:
  • plan-product.prompt.md - Initialize a new product
  • analyze-product.prompt.md - Add Agent OS to existing codebase
  • create-spec.prompt.md - Plan a new feature
  • execute-tasks.prompt.md - Build and ship code
  • tech-stack.instructions.md - Your tech stack standards
  • code-style.instructions.md - Your code style standards
  • best-practices.instructions.md - Your development practices

Download and run locally:

# Download the setup script
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/yldgio/agent-os-vscode/main/setup.ps1" -OutFile "setup.ps1"

# Run with parameters
.\setup.ps1 -OverwriteInstructions -OverwriteStandards
