Step 2: Create Setup Instructions ROOCODE_SETUP.md:

# RooCode Team Setup Guide

## Prerequisites
- RooCode application installed ([Download](https://roocode.io))
- MegaLLM API key ([Get yours](https://megallm.io/dashboard))

## Setup Steps

### 1. Get Your Personal API Key
1. Go to https://megallm.io/dashboard
2. Navigate to **API Keys**
3. Click **Create New Key**
4. Copy your key (starts with `sk-mega-`)

### 2. Import Team Configuration
1. Download `team-roocode-config.json` from this repo
2. Open RooCode
3. Go to: `File → Import Configuration`
4. Select `team-roocode-config.json`

### 3. Add Your Personal API Key
1. After import, go to: `Settings → API Configuration`
2. Replace `TEAM_MEMBER_REPLACES_THIS` with your actual key
3. Click **Test Connection** (should show ✓ Success)
4. Click **Save**

### 4. Restart RooCode
Close and reopen RooCode to apply all settings.

## Verification
1. Open a new chat
2. Type: `Generate a React component for a login form`
3. Should generate TypeScript code following Airbnb style

## Troubleshooting
- **Connection failed**: Check API key is correct
- **Wrong code style**: Verify configuration imported correctly
- **Model errors**: Ensure using `gpt-5` or other supported models

## Support
Contact team lead or check [MegaLLM Docs](https://docs.megallm.io)

Step 3: Distribute to Team

# Team lead commits to repo
git add team-roocode-config.json ROOCODE_SETUP.md
git commit -m "Add RooCode team configuration"
git push

# Team members clone and setup
git pull
# Follow instructions in ROOCODE_SETUP.md

Result: Entire team uses consistent:

Same AI model (gpt-5)
Same temperature and settings
Same custom prompts
Same coding standards
Personal API keys (not shared)

Scenario 3: Project-Specific Configurations

Use different RooCode configurations for different project types: Python Data Science Project: roocode-datascience.json:

{
  "provider": "openai-compatible",
  "api": {
    "baseURL": "https://ai.megallm.io/v1",
    "apiKey": "${env:MEGALLM_API_KEY}",
    "model": "claude-opus-4-1-20250805",
    "temperature": 0.5
  },
  "projectSettings": {
    "language": "python",
    "libraries": ["numpy", "pandas", "scikit-learn", "matplotlib"],
    "codingStyle": "pep8"
  },
  "customPrompts": {
    "analyze": "Analyze this data processing code for efficiency and correctness",
    "optimize": "Optimize this pandas operation for large datasets",
    "visualize": "Suggest matplotlib visualization for this data",

}

Switching Between Projects:

# Create aliases in ~/.bashrc or ~/.zshrc
alias roocode-ds='cp ~/configs/roocode-datascience.json ~/.config/RooCode/config.json && roocode'
alias roocode-web='cp ~/configs/roocode-webapp.json ~/.config/RooCode/config.json && roocode'
alias roocode-sys='cp ~/configs/roocode-systems.json ~/.config/RooCode/config.json && roocode'

Scenario 4: Migration from Cursor/Other AI Tools

Switching from another AI coding tool to RooCode with MegaLLM: Current Setup: Using Cursor with OpenAI Why Switch to RooCode + MegaLLM:

Access to multiple models (GPT, Claude, Gemini) with one key
Standalone app (not tied to specific editor)
Better pricing and no seat limits
More customization options

Migration Steps:

Export Current Preferences

From Cursor (if possible):

Note your preferred models
Save any custom prompts
Document keyboard shortcuts you use

Install RooCode

Download and install RooCode for your OS

Configure MegaLLM

{
  "provider": "openai-compatible",
  "api": {
    "baseURL": "https://ai.megallm.io/v1",
    "apiKey": "sk-mega-your-megallm-key",
    "model": "gpt-5"
  }
}

Recreate Custom Prompts

Add your frequently used prompts:

{
  "customPrompts": {
    "explain": "Explain this code in detail",
    "fix": "Find and fix bugs in this code",
    "improve": "Suggest improvements for this code"
  }
}

Test Functionality

Compare side-by-side:

Open same code in both tools
Ask same questions
Compare code generation quality
Evaluate response speed

Comparison Table:

Feature	Cursor	RooCode + MegaLLM
Editor Integration	VS Code fork	Standalone + Any Editor
Models Available	GPT-4, GPT-3.5	GPT, Claude, Gemini, and more
API Key	OpenAI only	One key for all models
Pricing	Per-seat subscription	Pay-per-use
Customization	Limited	Extensive
Offline Mode	No	No

Scenario 5: Multi-Model Workflow

Use different models for different types of tasks: Configuration with Model Profiles:

{
  "provider": "openai-compatible",
  "api": {
    "baseURL": "https://ai.megallm.io/v1",
    "apiKey": "sk-mega-your-api-key-here",
    "model": "gpt-5"
  },
  "modelProfiles": {
    "fast": {
      "model": "gpt-4o-mini",
      "temperature": 0.5,
      "maxTokens": 1000,
      "description": "Fast completions for simple tasks"
    },
    "balanced": {
      "model": "gpt-5",
      "temperature": 0.7,
      "maxTokens": 4096,
      "description": "Balanced quality and speed"
    },
    "quality": {
      "model": "claude-opus-4-1-20250805",
      "temperature": 0.3,
      "maxTokens": 8192,
      "description": "Highest quality for complex tasks"
    },
    "creative": {
      "model": "gpt-5",
      "temperature": 0.9,
      "maxTokens": 4096,
      "description": "Creative documentation and naming"
    },
    "analysis": {
      "model": "claude-sonnet-4",
      "temperature": 0.4,
      "maxTokens": 6000,
      "description": "Code review and analysis"
    }
  }
}

Workflow Example:

Morning: Rapid Prototyping

# Test connection
curl -I https://ai.megallm.io/v1/models

# Should return: HTTP/2 200

Check firewall:
- Allow RooCode through firewall
- Check corporate proxy settings
- Verify no VPN blocking

Increase timeout:

{
  "api": {
    "timeout": 60000  // Increase to 60 seconds
  }
}

Test API key manually:

curl -X POST https://ai.megallm.io/v1/chat/completions \
  -H "Authorization: Bearer $MEGALLM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-4o-mini","messages":[{"role":"user","content":"test"}]}'

API key not recognized

Symptoms:

“Invalid API key” error
401 Unauthorized
Authentication failed

Solutions:

Verify key format:
- Must start with sk-mega-
- Should be 60+ characters
- No extra spaces or line breaks
- No quotes in config file around the actual key
Check key is active:
- Login to Dashboard
- Go to API Keys
- Verify key shows as “Active”
- Check it’s not revoked or expired
Re-enter the key:
- Copy key from dashboard
- Delete old key from RooCode settings
- Paste new key
- Save and restart RooCode

Test key directly:

curl -H "Authorization: Bearer sk-mega-your-actual-key" \
     https://ai.megallm.io/v1/models

# Should return JSON list of models

Poor quality responses

Symptoms:

Irrelevant code suggestions
Wrong programming language
Incomplete responses

Solutions:

Provide better context:
- Set project language in settings
- Add framework information
- Use custom prompts

Adjust temperature:

{
  "api": {
    "temperature": 0.3  // Lower = more focused (0.2-0.4 for code)
  }
}

Try different model:

{
  "api": {
    "model": "claude-sonnet-4"  // Better for analysis
  }
}

Increase max tokens:

{
  "api": {
    "maxTokens": 8192  // Longer, more complete responses
  }
}

Use specific prompts:

{
  "customPrompts": {
    "generate": "Generate production-ready TypeScript code following best practices"
  }
}

Configuration not loading

Symptoms:

Settings revert after restart
Changes don’t apply
Using default configuration

Solutions:

Check config file location:

# Should be:
C:\Users\YourName\AppData\Roaming\RooCode\config.json

# Not:
C:\Program Files\RooCode\config.json  # Wrong!

Validate JSON syntax:

# Check for errors
cat config.json | python3 -m json.tool

# Should show formatted JSON or error

Check file permissions:

# Linux/macOS
chmod 644 ~/.config/RooCode/config.json

# Windows: Ensure user has read/write access

Reset to defaults:
- Backup current config
- Delete config.json
- Restart RooCode (creates new config)
- Reapply settings via UI

Application crashes or freezes

Symptoms:

RooCode crashes on startup
Freezes during long responses
Unresponsive UI

Solutions:

Check system resources:
- Close other applications
- Ensure 4GB+ RAM available
- Check CPU usage

Reduce max tokens:

{
  "api": {
    "maxTokens": 2048  // Reduce from 8192
  }
}

Disable streaming:

{
  "advanced": {
    "streamResponses": false
  }
}

Clear cache:

# Windows
rmdir /s "%APPDATA%\RooCode\cache"

# macOS/Linux
rm -rf ~/Library/Application\ Support/RooCode/cache
rm -rf ~/.config/RooCode/cache

Reinstall RooCode:
- Backup config.json
- Uninstall RooCode
- Download latest version
- Install and restore config

Best Practices

Project Configurations

Create separate configs for different project types

Model Profiles

Set up profiles for different tasks: fast, quality, creative

Custom Prompts

Define reusable prompts for common tasks

Monitor Usage

Check Dashboard regularly for token usage

Backup Configs

Keep backups of working configurations

Security

Use environment variables for API keys in shared configs

Advanced Tips

Environment Variables

RooCode supports environment variable substitution:

{
  "api": {
    "apiKey": "${env:MEGALLM_API_KEY}",
    "baseURL": "${env:MEGALLM_BASE_URL}"
  }
}

Set variables:

export MEGALLM_API_KEY="sk-mega-your-key"
export MEGALLM_BASE_URL="https://ai.megallm.io/v1"

Context Management

Improve responses with better context:

{
  "advanced": {
    "contextWindowSize": 16000,
    "includeProjectStructure": true,
    "includeOpenFiles": true,
    "maxRelevantFiles": 10
  }
}

Response Caching

Save API costs with intelligent caching:

{
  "advanced": {
    "cacheResponses": true,
    "cacheExpiry": 3600,  // seconds
    "maxCacheSize": 100   // MB
  }
}
