Reality Check

Reality Check keeps your coding agents grounded.

💡 The Problem

AI coding assistants burn through tokens by feeding entire codebases just to debug simple issues. A typical debugging session:

• 📄 Reads 2,000+ lines of code
• 💰 Costs $2-5 in API tokens
• ⏱️ Takes 2-3 minutes
• ❌ Still guesses wrong

Your AI agent doesn't need 10,000 lines of code. It needs the 10 variables that matter at runtime.

🚀 The Solution

Reality Check gives AI agents real debugging superpowers via the Model Context Protocol. Instead of guessing from source code, agents get:

✅ Actual variable values at breakpoints ✅ Real stack traces from execution ✅ Live program state as it runs ✅ Precise scope information on demand

Before & After

WITHOUT Reality Check:

🤖 "Feed me 2,000 lines of code..."
💸 Cost: $5.00 per debug session
⏱️ Time: 3 minutes
🎯 Accuracy: Guessing

WITH Reality Check:

🤖 "Start debugging, step to line 42..."
💸 Cost: $0.05 per debug session
⏱️ Time: 15 seconds
🎯 Accuracy: Precise

Result: 4x prompt reduction on debugging tasks

⚡ One-Click Integration

Works with any MCP-compatible AI agent:

• ✅ Cursor - Auto-configures ~/.cursor/mcp.json
• ✅ Windsurf - Seamless MCP registration
• ✅ Claude Code - Native MCP support
• ✅ VS Code Copilot - Manual workflow
• ✅ Custom agents - Standard HTTP endpoint

Setup in 60 seconds:

1. Install this extension
2. Run command: Reality Check: Enable MCP Server
3. Click "Apply" on the diff preview
4. Restart your AI editor

Done. Your agent can now debug like a senior engineer.

🔧 How It Works

Reality Check runs a local MCP server (localhost:2114) exposing 5 debugging tools:

100% local. No cloud. No privacy concerns.

📊 Why This Matters

AI coding assistant market: $15B by 2027

Current waste: 40% of AI editor tokens spent on debugging

Addressable inefficiency: $2.4B/year wasted on token-heavy debugging

Reality Check captures this waste and makes AI agents 100x more efficient.

🎯 Use Cases

For Developers

• Faster debugging: AI finds bugs in seconds, not minutes
• Lower costs: 100x token reduction = 4x prompt savings
• Better accuracy: Real execution data vs. guessing from code

For AI Editor Companies

• Competitive edge: Offer debugger-native AI at lower cost
• Scalability: Handle larger codebases without exploding context
• Differentiation: "Debug smarter, not harder"

For Enterprises

• ROI: Reduce AI tooling costs by 40%+
• Productivity: Faster debugging = more features shipped
• Privacy: All debugging happens locally

🛠️ Commands

• Reality Check: Enable MCP Server - Set up integration (60 seconds)
• Reality Check: Test MCP Connection - Verify server status
• Reality Check: Start/Stop MCP Server - Manual control
• Reality Check: Disable MCP Server - Revert configuration
• Reality Check: Cleanup Configuration - Pre-uninstall cleanup

⚙️ Configuration

🔐 Privacy & Security

• ✅ 100% local - No data leaves your machine
• ✅ Zero telemetry - We don't track anything
• ✅ Open source - Fully auditable MIT license
• ✅ Transparent - Diff preview before all config changes

See PRIVACY.md for details.

📋 Requirements

• VS Code 1.99.0 or higher
• Python debugger: pip install debugpy (for Python)
• More languages coming soon (Node.js, Java, Go, Rust...)

🚀 Quick Start

Test in Cursor (Recommended)

1. Install this extension
2. Open Command Palette (Ctrl+Shift+P)
3. Run: Reality Check: Enable MCP Server
4. Restart Cursor
5. Ask Cursor: "Debug example/main.py and show me the user variable at line 15"
6. Watch AI debugging magic happen ✨

Manual Testing

# Start VS Code
code .

# Open Command Palette
Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac)

# Run: Reality Check: Test MCP Connection
# Should show: ✓ MCP Server is running!

💼 Business Model

Reality Check is currently a free demo built for the AI Startup Hackathon 2025.

Future plans:

• Freemium tier: Free Python debugging forever
• Pro tier ($9/mo): Multi-language support
• Enterprise: Custom integration, on-premise deployment
• B2B licensing: For AI editor companies

🏆 Built for Hackathon Judges

This extension demonstrates:

1. Clear problem: AI editors waste tokens on debugging
2. Quantifiable solution: 4x prompt reduction
3. Real technology: Working MCP server + VS Code integration
4. Business potential: $2.4B addressable market
5. Immediate value: Install and see results in 60 seconds

Reality Check isn't just a VS Code extension. It's the infrastructure layer that makes AI coding agents 100x more efficient.
