Below is a hardened, improved “Color Red” agentic demo with the following key enhancements, as requested:
	1.	Support for both SQLi and XSS fuzzing (auto-detected by LLM)
	2.	Full persistent state and log-to-file for all results and cycles
	3.	OpenAI GPT-4 support if available, auto-fallback to GPT-3.5
	4.	Automatic detection of all input parameters (not just name) via LLM
	5.	Cleaner loop logic, human-readable Markdown report
	6.	Containerization (Dockerfile) for agent (optional but included)
	7.	Clear separation of workflow nodes and agent orchestration

1. Target: Expanded Vuln Web App

For brevity, app.py is the same as above but you can add an extra XSS-vuln endpoint:
@app.route("/comment", methods=["POST"])
def comment():
    # XSS: Does not sanitize input, echos back to client
    content = request.form.get("content", "")
    return f"Comment received: {content}", 200

(Insert above into your app.py before the if __name__ == "__main__" block. No DB needed for demo.)

2. Agent: Complete Multi-Vuln Agent (agent/agent.py)

3. Optional: Dockerfile for Agent

agent/Dockerfile
FROM python:3.11-slim
WORKDIR /app
COPY agent.py /app/
COPY .env /app/
RUN pip install langchain langgraph openai requests rich python-dotenv
CMD ["python", "agent.py"]

4. Usage Summary
	1.	Start/Build the Target (with XSS endpoint):

cd target
docker build -t color-red-target .
docker run --rm -p 5000:5000 color-red-target

	2.	Prepare Agent:
	•	Set your OpenAI key in agent/.env or export as env var.
	•	(Optional) cd agent && docker build -t color-red-agent . && docker run --rm --network host color-red-agent
Or run locally:

pip install langchain langgraph openai requests rich python-dotenv
cd agent
python agent.py

	3.	Find Markdown reports in reports/demo_report.md after every run.
