🎯 Coda: AI Coding Made Simple & Safe

A universal orchestration layer that sits between you and AI coding assistants (Claude, Gemini, Aider, etc.), adding safety features, memory, cost controls, and workflow automation.

🤔 What is Coda?

Imagine you hired a brilliant programmer to help you write code, but:

• They might accidentally delete important files
• They could spend too much money (API costs)
• They might forget what you discussed yesterday
• They could introduce security bugs
• You have no "undo" button if something goes wrong

Coda is like a safety harness and toolkit for AI programmers. It adds:

• 🛡️ Safety features - Automatic backups and rollback
• 💰 Cost controls - Set spending limits
• 🧠 Memory - Remembers context between sessions
• 🔒 Security checks - Scans for vulnerabilities
• 🤝 Multi-AI support - Use the best tool for each task

✨ Key Features

Core Safety & Control

• ⏮️ Checkpoint/Rollback System - Create restore points before changes
• 💰 Cost Tracking & Limits - Monitor API usage and set daily/monthly limits
• 🔒 Security Scanner - Automatic detection of hardcoded secrets and vulnerabilities
• 👁️ Diff Preview - See changes before applying them
• 🧠 Persistent Memory - Save and recall important context across sessions

AI Provider Support

• 🤖 Claude Code - Anthropic's CLI-based assistant
• 🌟 Gemini - Google's AI coding assistant
• 🎯 Aider - Git-aware pair programming
• 🐙 GitHub Copilot CLI - GitHub's command line AI
• 🚀 Cline.ai - Autonomous coding agent
• 📝 Cody - Sourcegraph's context-aware assistant
• 🔧 Amazon Q - AWS coding assistant
• 🎨 Continue.dev - Open-source extensible AI

Workflow Enhancement

• 📋 Workflow Templates - Automate repetitive task sequences
• 🧪 Test Generation - AI-powered test creation with coverage tracking
• 📚 Documentation Search - RAG-powered project documentation search
• 🌐 Offline Mode - Cached responses for working without internet
• 🎨 Preset Configurations - Quick switching between safety levels
• 🔧 Interactive Wizard - Easy setup for beginners

🚀 Quick Start

Prerequisites

• Node.js 18+ (Download)
• Git (for version control features)
• At least one AI provider installed

Installation

# Using npm (recommended)
npm install -g coda-cli

# Using yarn
yarn global add coda-cli

# Using pnpm
pnpm add -g coda-cli

# On macOS with Homebrew
brew tap coda/tap
brew install coda-cli

First Time Setup

# Run the interactive wizard
coda wizard

# Or quick setup
coda init

The wizard will:

1. Detect installed AI providers
2. Configure safety settings
3. Set up cost limits
4. Create your first preset

Basic Usage

# Start a conversation with your default AI
coda

# Send a specific request
coda "Fix the error in my React component"

# Use a specific provider
coda --provider aider "Refactor this function"

# Check your setup
coda doctor

📖 Real-World Examples

Example 1: Safe Development Workflow

# Morning routine
coda checkpoint create "morning-start"
coda costs show --yesterday

# Before big changes
coda checkpoint create "before-refactor"
coda "Refactor the authentication system"
coda security scan
coda test generate

# Oops, something broke!
coda checkpoint rollback

Example 2: Learning to Code Safely

# Safe learning environment
coda preset apply cautious
coda checkpoint create "learning-python"

# Ask questions freely
coda "Explain Python decorators with examples"
coda "Help me write a web scraper"

# Save important lessons
coda memory save "python-tips" "Use requests.get() for HTTP requests"

Example 3: Cost-Conscious Development

# Set spending limits
coda costs set-limit --daily 10
coda costs set-limit --monthly 200

# Work efficiently with caching
coda offline enable
coda "Create a REST API endpoint"  # Uses AI
coda "Create a REST API endpoint"  # Uses cache!

# Track spending
coda costs show --this-month
coda costs export january-invoice.json

"Coda command not found"

# Check Node.js installation
node --version

# Reinstall Coda
npm install -g coda-cli

# Add to PATH manually (if needed)
export PATH="$PATH:$(npm root -g)/bin"

"AI provider not found"

# Check what's available
coda doctor

# Install missing provider
# Example for Aider:
pip install aider-install

"Spending limit reached"

# Check current usage
coda costs show --today

# Increase limit temporarily
coda costs set-limit --daily 20

# Use offline mode
coda offline enable
