+
+## 📦 Tech Stack
+
+**Backend:**
+- FastAPI (async web framework)
+- SQLModel (ORM with Pydantic)
+- Alembic (migrations)
+- Celery (task queue)
+- Redis (broker)
+- Jinja2 (templating)
+- OpenAI API / Ollama
+
+**Frontend:**
+- Next.js 14 (App Router)
+- TypeScript
+- Tailwind CSS
+- Axios
+- Recharts
+
+**Infrastructure:**
+- Docker & Docker Compose
+- PostgreSQL 16
+- Redis 7
+
+## 🔒 Security Notes
+
+For production deployment:
+1. Generate secure SECRET_KEY: `openssl rand -hex 32`
+2. Use strong database passwords
+3. Enable HTTPS/TLS
+4. Restrict CORS origins
+5. Add rate limiting
+6. Sandbox Python code execution (RestrictedPython)
+7. Implement OAuth providers
+
+## 📈 Performance
+
+- Async FastAPI for concurrent requests
+- Celery for background job processing
+- Redis caching and job queue
+- SSE for real-time updates
+- Connection pooling
+- Database indexing on common queries
+
+## 🎨 UI/UX
+
+- Clean, modern interface with Tailwind CSS
+- Responsive design (mobile-friendly)
+- Color-coded event types in Mirror
+- Loading states and error handling
+- Modal dialogs for details
+- Search and filtering
+- Tabbed navigation in Studio
+
+## 🐛 Known Limitations
+
+1. Python code execution is **not sandboxed** (use RestrictedPython in prod)
+2. Star/rate system is simplified (no per-user tracking)
+3. SSE timeout is 60 seconds
+4. File uploads not implemented for CSV specs (YAML only)
+5. No OAuth integration yet (JWT only)
+6. Basic token estimation for Ollama
+
+## 🚀 Next Steps
+
+To start using:
+
+1. **Set environment variables** (especially `OPENAI_API_KEY`)
+2. **Start services**: `docker compose up -d --build`
+3. **Run migrations**: `docker compose exec api alembic upgrade head`
+4. **Seed data**: `docker compose exec api python -m app.seed`
+5. **Open browser**: http://localhost:3000
+6. **Login** with `test@example.com` / `Passw0rd!`
+7. **Try the Studio** to create your first agent!

+
+```yaml
+version: "1"
+agent:
+  name: "research-assistant"
+  description: "Searches the web and summarizes findings"
+  model:
+    provider: "openai"
+    model_name: "gpt-4o-mini"
+    temperature: 0.2
+  inputs:
+    - name: "topic"
+      type: "string"
+      required: true
+  steps:
+    - id: "search"
+      tool: "http_get"
+      args:
+        url: "https://api.example.com/search?q={{ inputs.topic }}"
+    - id: "summarize"

+      args:
+        system: "You are a research analyst."
+        user: "Summarize these search results: {{ steps.search }}"
+  outputs:
+    - name: "summary"
+      type: "markdown"
+```
+
+Then upload via the UI or API.
+
+## 🛠️ Development
+
+### Local Development (Backend)
+
+```bash
+cd apps/api
+
+# Create virtual environment
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Run migrations
+alembic upgrade head
+
+# Start dev server
+uvicorn app.main:app --reload
+```
+
+### Local Development (Frontend)
+
+```bash
+cd apps/web
+
+# Install dependencies
+npm install
+
+# Start dev server
+npm run dev
+```
+
+### Run Tests
+
+```bash
+# Backend tests
+docker compose exec api pytest
+
+# Or locally
+cd apps/api
+pytest
+```
+
+## 🎨 Built-in Skills
+
+The platform includes these skills out of the box:
+
+1. **http_get** - Fetch data via HTTP GET
+2. **pdl_enrich** - Enrich contacts with PeopleDataLabs (mock)
+3. **llm_prompt** - Execute LLM prompts
+4. **csv_write** - Write data to CSV
+5. **markdown_export** - Export content as Markdown
+
+## 🌐 Services
+
+The stack includes:
+
+- **API** (FastAPI) - `http://localhost:8000`
+- **Web** (Next.js) - `http://localhost:3000`
+- **PostgreSQL** - `localhost:5432`
+- **Redis** - `localhost:6379`
+- **Worker** (Celery) - Background tasks
+- **Ollama** (optional) - `localhost:11434`
+
+### Enable Ollama (Local Models)
+
+```bash
+# Start with Ollama profile
+docker compose --profile ollama up -d
+
+# In .env, set:
+# LLM_PROVIDER=ollama
+```
+
+## 📊 Tech Stack
+
+**Backend:**
+- FastAPI (async Python web framework)
+- SQLModel (SQL databases with Python types)
+- Alembic (database migrations)
+- Celery (distributed task queue)
+- Redis (broker & cache)
+- Jinja2 (code templating)
+- OpenAI API / Ollama (LLM providers)
+
+**Frontend:**
+- Next.js 14 (App Router)
+- TypeScript
+- Tailwind CSS
+- shadcn/ui components
+- Recharts (charts)
+- Zustand (state management)
+
+**Infrastructure:**
+- Docker & Docker Compose
+- PostgreSQL
+- Redis
+
+## 🧪 Example Workflows
+
+### Create and Run an Agent
+
+1. Navigate to **Studio** (`/studio`)
+2. Enter agent slug: `weather-bot`
+3. Enter agent name: `Weather Bot`
+4. Paste your YAML spec
+5. Click **Validate** → **Create Agent**
+6. Switch to **Generate** tab → **Generate Agent Code**
+7. Switch to **Run** tab → **Run Agent**
+8. Check **Mirror** (`/mirror`) to visualize execution
+
+### Browse and Fork a Skill
+
+1. Navigate to **Skills** (`/skills`)
+2. Search or filter by category
+3. Click a skill card to view details
+4. Click **Fork** to create your own version
+5. Click **Star** to bookmark
+
+### Test a Prompt Flow
+
+1. Navigate to **Sandbox** (`/sandbox`)
+2. Add prompt steps
+3. Define variables
+4. Click **Run Prompt Flow**
+5. View cost and token estimates
+
+## 🔒 Security Notes
+
+⚠️ **Important for Production:**
+
+1. Change `SECRET_KEY` in `.env` to a secure random value
+2. Use a strong password for PostgreSQL
+3. Enable HTTPS/TLS
+4. Restrict CORS origins in `app/main.py`
+5. Sandbox Python code execution (currently unsafe)
+6. Add rate limiting
+7. Implement proper OAuth if needed
+
+## 🐛 Troubleshooting
+
+### Port Conflicts
+
+If ports 3000, 8000, 5432, or 6379 are in use:
+
+```bash
+# Stop services
+docker compose down
+
+# Edit compose.yaml to use different ports
+# Then restart
+docker compose up -d
+```
+
+### Database Issues
+
+```bash
+# Reset database
+docker compose down -v
+docker compose up -d
+task migrate
+task seed
+```
+
+### See Logs
+
+```bash
+# All services
+docker compose logs -f
+
+# Specific service
+docker compose logs -f api
+docker compose logs -f web
+docker compose logs -f worker
+```
+
+## 📚 Additional Commands
+
+```bash
+# Shell into API container
+docker compose exec api /bin/bash
+
+# Shell into Web container
+docker compose exec web /bin/sh
+
+# Restart a service
+docker compose restart api
+
+# Rebuild a service
+docker compose up -d --build api
+```
+
+## 🎯 Roadmap
+
+- [ ] OAuth integration (Google, GitHub)
+- [ ] Agent marketplace with versioning
+- [ ] Real-time collaboration
+- [ ] More built-in skills (email, SMS, database)
+- [ ] Agent scheduling and cron
+- [ ] Multi-tenancy
+- [ ] Audit logs
+- [ ] Webhooks for events

+## Setup
+
+1. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+2. Configure environment:
+```bash
+cp .env.example .env
+# Edit .env with your API keys
+```
+
+3. Run the agent:
+```bash
+python app.py
+```
+
+## Usage
+
+The agent exposes a POST endpoint at `/run`:
+
+```bash
+curl -X POST http://localhost:8000/run \
+  -H "Content-Type: application/json" \
+  -d '{
+{% for input in spec.agent.inputs %}
+    "{{ input.name }}": "your-value-here"{% if not loop.last %},{% endif %}
+
+{% endfor %}
+  }'
+```
+
+## Generated by Smartr Agent Studio
+
+This agent was automatically generated from a YAML specification.
