5-Minute Setup

Step 1: Install Dependencies

cd public
npm install

Step 2: Get API Keys (5 minutes)

Google Gemini API Key:

Visit: https://makersuite.google.com/app/apikey
Click "Create API key"
Copy the key

GEMINI_API_KEY=your_key_here
GITHUB_TOKEN=your_token_here
HF_TOKEN=your_token_here
GITHUB_REPO=YourUsername/your-repo
GITHUB_OWNER=YourUsername

Step 4: Start

npm start

Step 5: Visit

Open: http://localhost:3000

Deploy to HF Spaces

Step 1: Add GitHub Secrets

In GitHub repo → Settings → Secrets → Actions:

HF_TOKEN        = your_hf_token
HF_USERNAME     = your_username
HF_SPACE_NAME   = your-space-name

Step 2: Push to GitHub

git add public/
git commit -m "feat: add ai agent"
git push origin main

Step 3: GitHub Actions Deploys Automatically

Builds Docker image
Pushes to HF Space
Service starts on HF

API Examples

Start Chat

curl -X POST http://localhost:3000/api/chat/start
# Response: {"sessionId": "session_1234_xyz"}

Send Message

curl -X POST http://localhost:3000/api/chat/message \
  -H "Content-Type: application/json" \
  -d '{
    "sessionId": "session_1234_xyz",
    "message": "What is the main issue in this project?"
  }'

Run Scanner

curl -X POST http://localhost:3000/api/scanner/scan

Get Project Info

curl http://localhost:3000/api/project/structure
curl http://localhost:3000/api/project/readme
curl http://localhost:3000/api/project/dockerfile

Configuration Reference

.env Variables

Required:

GEMINI_API_KEY=your_gemini_key
GITHUB_TOKEN=your_github_token
HF_TOKEN=your_hf_token

Repository:

GITHUB_REPO=YourUsername/repo-name
GITHUB_OWNER=YourUsername
GITHUB_BRANCH=main

Scanner:

SCAN_INTERVAL=3600000              # 1 hour in milliseconds
ENABLE_AUTO_FIX=true              # Auto-fix detected issues
AUTO_COMMIT=false                 # Auto-commit to GitHub

Server:

PORT=3000                         # Server port
NODE_ENV=production               # Environment
LOG_LEVEL=info                    # Logging level (debug/info/warn/error)
DEBUG=false                       # Verbose output

How It Works

On Startup

Server starts (port 3000)
  ↓
Validate env variables
  ↓
Initialize services (Gemini, GitHub, Project)
  ↓
Start periodic scanner (if enabled)
  ↓
Ready for requests

Every 1 Hour (Scanning)

Timer triggers
  ↓
Read project from GitHub
  ↓
Detect issues
  ↓
Analyze code with AI
  ↓
Generate recommendations
  ↓
Create GitHub issue (if issues found)
  ↓
Store report for UI

On User Message

User types in chat
  ↓
Send to API
  ↓
Load project context
  ↓
Call Gemini AI
  ↓
Return response
  ↓
Display in UI

Troubleshooting

"API key not valid"

Check .env file
Regenerate key if expired
Paste exact key without spaces

"Failed to connect to GitHub"

Verify GITHUB_TOKEN in .env
Check token has repo scope
Verify GITHUB_REPO format: owner/repo

"Port 3000 already in use"

# Windows
Get-Process -Name node | Stop-Process -Force

"Scan not running"

Check ENABLE_AUTO_FIX=true
Verify SCAN_INTERVAL is milliseconds
Check logs: npm run dev

"Slow responses"

Check internet connection
Simplify your prompts
Increase timeout in src/config/env.js

Development Mode

# Install nodemon
npm install --save-dev nodemon

# Run with auto-reload
npm run dev

Watch mode shows detailed logs for debugging.

Production Deployment

Docker image is configured for HF Spaces:

FROM node:18-alpine
WORKDIR /app
COPY public /app
RUN npm ci --omit=dev
EXPOSE 7860
CMD ["npm", "start"]

HF Spaces automatically:

Builds image
Runs container on port 7860
Exposes via HTTPS URL

Documentation

README.md - Features and quick start
INSTALLATION.md - Detailed setup guide (400 lines)
ARCHITECTURE.md - Design and how to extend
AIAGENT_COMPLETE.md - Complete implementation summary

Support

All API keys are in .env - never commit this file!

Keep .gitignore to prevent accidental commits of:

node_modules/
.env
.env.local
*.log

Security

✅ Keys in Environment - Never in code ✅ GitHub Secrets - Token stored securely
✅ Input Sanitization - HTML escaping ✅ No Logs Exposed - Stack traces hidden ✅ HTTPS Ready - Works with reverse proxy

Success Indicators

After setup:

✅ Server starts without errors
✅ Web UI loads at localhost:3000
✅ /help command returns text
✅ /status shows repo info
✅ /scan completes in 30-60 sec
✅ Chat responds with AI output

What Happens Next

Hourly Scans - Automated every hour
GitHub Issues - Created for critical findings
Chat Logs - Stored in memory (not persisted)
Auto-Fixes - Created as draft PRs (review before merge)

One Command Deploy

# After first setup:
git add public && git commit -m "AI Agent ready" && git push origin main

# Then wait ~5 minutes for HF Space build
