🎯 Overview

WYN360 CLI is an AI-powered coding assistant that helps you build projects, generate code, and improve your codebase through natural language conversations. Built with pydantic-ai and Anthropic Claude, it provides intelligent file operations, command execution, and context-aware assistance.

🏗️ System Architecture

For a detailed architecture overview including all components, layers, and data flows, see SYSTEM.md.

📦 Installation

Basic Installation

pip install wyn360-cli

Optional: Enable Browser Use (Direct Website Fetching)

If you want to use the fetch_website feature to read specific URLs directly:

# Install Playwright browser binaries (one-time setup, ~200MB)
playwright install chromium

Note: Browser use is optional. Web search and all other features work without it. Only install if you need direct URL fetching (e.g., "Read https://github.com/user/repo").

🚀 Quick Start

1. Choose your AI provider and set up credentials:

WYN360 CLI supports four AI providers. Choose one:

---

Option 1: Anthropic Claude (Direct API)

Using environment variables:

export CHOOSE_CLIENT=2
export AWS_ACCESS_KEY_ID=your_access_key
export AWS_SECRET_ACCESS_KEY=your_secret_key
export AWS_SESSION_TOKEN=your_session_token
export AWS_REGION=us-west-2
export ANTHROPIC_MODEL=us.anthropic.claude-sonnet-4-20250514-v1:0

Using .env file (recommended):

Option 3: Google Gemini 🆕

Using environment variables:

export CHOOSE_CLIENT=3
export GEMINI_API_KEY=your_key_here
export GEMINI_MODEL=gemini-2.5-flash

Using .env file (recommended):

# Create .env file in your project directory
CHOOSE_CLIENT=3
GEMINI_API_KEY=your_key_here
GEMINI_MODEL=gemini-2.5-flash

Get your API key: Google AI Studio Available models: gemini-2.5-flash (fast, cheap), gemini-2.5-pro (powerful) Cost: ~40x cheaper than Claude! ($0.075/M vs $3.00/M input tokens)

Features:

OPENAI_MODEL=gpt-4o

Get your API key: OpenAI Platform Available models: gpt-4o (latest), gpt-4 (stable), gpt-3.5-turbo (fast) Cost: Competitive pricing with good performance

Features:

• ✅ All tools supported (file ops, git, docs, browser, etc.)
• ✅ 128K token context window
• ✅ Industry-leading performance
• ✅ Fast response times

---

Auto-Detection (No CHOOSE_CLIENT)

If you don't set CHOOSE_CLIENT, the system will auto-detect based on available credentials:

Priority order:

1. ANTHROPIC_API_KEY → Use Anthropic
2. AWS credentials → Use Bedrock
3. GEMINI_API_KEY → Use Google Gemini
4. OPENAI_API_KEY → Use OpenAI

# Just set your preferred API key
export GEMINI_API_KEY=your_key_here
# System will automatically use Gemini

2. Run the CLI:

wyn360

3. Start chatting:

You: Build a Streamlit app for data visualization

WYN360: I'll create a Streamlit app for you...
