### Lead Magnet Content (The Checklist)

**Introduction (2-3 sentences)**
Most developers get stuck between “it works on my machine” and “it works in production.” This checklist is your guardrail. It ensures you don’t waste time on the wrong model, the wrong cloud config, or a security hole. Use this to validate your stack *before* you start Day 1 of the full course.

#### The 8-Step Launchpad Checklist

**1. Define the “Chatbot Job” (Not the Tech)**
– [ ] **Identify the single use case:** Is this a customer support FAQ bot, a code assistant, or a data retrieval agent?
– [ ] **Set an accuracy threshold:** Define “good enough” (e.g., 85% correct answers vs. 99% for medical advice). *Don’t optimize for perfection on Day 1.*
– [ ] **Choose the memory type:** Will the bot remember the last 5 messages (short-term) or past sessions (long-term via vector DB)?

**2. Select Your Model & Hosting Strategy (Trade-off Analysis)**
– [ ] **Evaluate “Open vs. Closed” models:** GPT-4o (costly, high quality) vs. Llama 3 (free, needs GPU) vs. Mistral (balance).
– [ ] **Decide on inference location:** Cloud API (OpenAI) vs. Self-hosted (RunPod/Replicate).
– [ ] **Lock in a fallback:** What happens if the API is down? (e.g., a simple “I'm offline” response vs. a cached answer).

**3. Scaffold the Backend (The “Brain”)**
– [ ] **Set up a FastAPI server** (or Node.js/Express). *Why FastAPI? Async support for multiple user requests + automatic OpenAPI docs.*
– [ ] **Create a single `/chat` endpoint** that accepts `{user_input}` and returns `{bot_response}`.
– [ ] **Implement basic rate limiting** (e.g., 10 requests/min per user) to prevent runaway costs.

**4. Build the Frontend (The “Face”)**
– [ ] **Use a lightweight framework:** Streamlit (fastest for prototypes) or Next.js (for production polish).
– [ ] **Implement streaming responses** (Server-Sent Events) so the user sees text appear in real-time (not a 10-second wait).
– [ ] **Add a “Loading” state** and a “Clear Chat” button. *Do not add authentication yet—keep it local for testing.*

**5. Containerize Everything (Docker)**
– [ ] **Create a `Dockerfile` for the backend** (Python 3.11 slim + requirements.txt).
– [ ] **Create a `Dockerfile` for the frontend** (Node 20 alpine + static build).
– [ ] **Write a `docker-compose.yml`** that links the two services on a shared network. *Test that `localhost:3000` can talk to `backend:8000`.*

**6. Automate Infrastructure with IaC (Terraform)**
– [ ] **Write a `main.tf` to provision:**
– A cheap VM (e.g., AWS t3.medium or a free-tier instance).
– A security group allowing ports 80 (HTTP) and 443 (HTTPS).
– [ ] **Add a simple Cloudflare or AWS Route53 DNS record** pointing to the VM IP.
– [ ] **Run `terraform plan`** to confirm no accidental public S3 buckets or open databases.

**7. Implement the CI/CD Pipeline (GitHub Actions)**
– [ ] **Create `.github/workflows/deploy.yml`:**
– On push to `main`: Build Docker images.
– Push images to Docker Hub or GitHub Container Registry.
– SSH into the VM and run `docker-compose pull && docker-compose up -d`.
– [ ] **Test the pipeline:** Make a trivial change (e.g., change the bot greeting) and verify it auto-deploys in under 3 minutes.

**8. Apply the “Minimum Viable Security” Layer**
– [ ] **Add an API key header** to the backend (passed by the frontend). *Don't expose your OpenAI key in the browser.*
– [ ]
