# Credit Risk Case Copilot
|
||||
|
||||
A production-ready multi-agent credit risk assessment system demonstrating Plano's intelligent orchestration, guardrails, and prompt targets. This demo showcases a sophisticated workflow that analyzes loan applications, performs policy compliance checks, generates decision memos, and creates cases with full observability.
|
||||
|
||||
## Overview
|
||||
|
||||
This demo implements a **Credit Risk Case Copilot** with:
|
||||
|
||||
- **Risk Crew Agent** - Multi-agent workflow for comprehensive risk assessment
|
||||
- **Case Service** - Case management API for storing decisions
|
||||
- **PII Security Filter** - MCP filter for redacting sensitive data and detecting prompt injections
|
||||
- **Streamlit UI** - Interactive web interface for risk analysts
|
||||
- **Jaeger Tracing** - End-to-end distributed tracing across all services
|
||||
|
||||
All services communicate through **Plano's orchestrator** which handles intelligent routing, model selection, guardrails, and function calling.
|
||||
|
||||
## Features
|
||||
|
||||
- **Multi-Agent Risk Assessment**: Intake normalization, risk scoring, policy checks, and decision memo generation
|
||||
- **Risk Band Classification**: LOW/MEDIUM/HIGH with confidence scores
|
||||
- **Driver Analysis**: Identifies top risk factors with supporting evidence
|
||||
- **Policy Compliance**: Automated checks for KYC, income verification, and lending standards
|
||||
- **Document Requirements**: Auto-generated based on risk profile
|
||||
- **Security Guardrails**: PII redaction (CNIC, phone, email) and prompt injection detection
|
||||
- **Case Management**: Create and track risk cases with audit trails
|
||||
- **OpenTelemetry Tracing**: Full observability across UI → Plano → Agents → LLMs → APIs
|
||||
|
||||
## Architecture

|
||||
Plano Orchestrator (8001)

|
||||
↓
|
||||
Case Service (10540)
|

Jaeger (16686)
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Docker and Docker Compose
|
||||
- [Plano CLI](https://docs.planoai.dev) installed (`pip install planoai` or `uvx planoai`)
|
||||
- OpenAI API key
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Set Environment Variables
|
||||
|
||||
Copy the example environment file and add your API key:
|
||||
|
||||
```bash
|
||||
cp .env.example .env
|
||||
# Edit .env and add your OPENAI_API_KEY
|
||||
```
|
||||
|
||||
Or export directly:
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY="your-openai-api-key"
|
||||
```
|
||||
|
||||
### 2. Start Docker Services
|
||||
|
||||
Start all containerized services (agents, UI, Jaeger):
|
||||
|
||||
```bash
|
||||
docker compose up --build
|
||||
```
|
||||
|
||||
This starts:
|
||||
- **Risk Crew Agent** on port 10530
|
||||
- **Case Service** on port 10540
|
||||
- **PII Filter** on port 10550
|
||||
- **Streamlit UI** on port 8501
|
||||
- **Jaeger** on port 16686
|
||||
|
||||
### 3. Start Plano Orchestrator
|
||||
|
||||
In a new terminal, start Plano (runs on host, not in Docker):
|
||||
|
||||
```bash
|
||||
cd /path/to/credit_risk_case_copilot
|
||||
planoai up config.yaml
|
||||
|
||||
# Or if installed with uv:
|
||||
# uvx planoai up config.yaml
|
||||
```
|
||||
|
||||
The orchestrator will start on:
|
||||
- Port **8001** - Agent listener (main entry point)
|
||||
- Port **12000** - LLM gateway (for agents to call)
|
||||
- Port **10000** - Prompt listener (for function calling)
|
||||
|
||||
### 4. Access the UI
|
||||
|
||||
Open your browser to:
|
||||
|
||||
- **Streamlit UI**: http://localhost:8501
|
||||
- **Jaeger Tracing**: http://localhost:16686
|
||||
|
||||
## Using the Demo
|
||||
|
||||
### Streamlit UI Workflow
|
||||
|
||||
1. **Select a Scenario** (or paste your own JSON):
|
||||
- 🟢 **Scenario A** - Low risk (stable job, good credit, low DTI)
|
||||
- 🟡 **Scenario B** - Medium risk (thin file, missing verifications)
|
||||
- 🔴 **Scenario C** - High risk + prompt injection attempt
|
||||
|
||||
2. **Click "Assess Risk"** - Plano routes to Risk Crew Agent
|
||||
|
||||
3. **View Results** in tabs:
|
||||
- **Risk Summary**: Normalized data and overview
|
||||
- **Risk Drivers**: Top factors with evidence
|
||||
- **Policy & Compliance**: Checks, exceptions, required documents
|
||||
- **Decision Memo**: Bank-ready memo with recommendation
|
||||
- **Audit Trail**: Models used, timestamps, request ID
|
||||
|
||||
4. **Create Case** - Stores assessment in Case Service
|
||||
|
||||
### Direct API Testing
|
||||
|
||||
You can also send requests directly to Plano:
|
||||
|
||||
```bash
|
||||
curl http://localhost:8001/v1/chat/completions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"model": "gpt-4o",
|
||||
"messages": [
|
||||
{
|
||||
"role": "user",
|
||||
"content": "Assess credit risk for this application: {\"applicant_name\": \"Sarah Ahmed\", \"loan_amount\": 300000, \"credit_score\": 780, \"monthly_income\": 200000, \"total_debt\": 25000, \"delinquencies\": 0, \"kyc_complete\": true, \"income_verified\": true}"
|
||||
}
|
||||
]
|
||||
}'
|
||||
```
|
||||
|
||||

## Service Details
|
||||
|
||||
### Risk Crew Agent (Port 10530)
|
||||
|
||||
Multi-step workflow:
|
||||
1. **Intake & Normalization** - Extract and validate data
|
||||
2. **Risk Scoring** - Calculate DTI, assess credit, classify band
|
||||
3. **Policy Checks** - Verify KYC, income, address, lending limits
|
||||
4. **Decision Memo** - Generate bank-ready recommendation
|
||||
|
||||
### Case Service (Port 10540)
|
||||
|
||||
RESTful API for case management:
|
||||
- `POST /cases` - Create new case
|
||||
- `GET /cases/{case_id}` - Retrieve case
|
||||
- `GET /cases` - List all cases
|
||||
- `GET /health` - Health check
|
||||
|
||||
### PII Security Filter (Port 10550)
|
||||
|
||||
MCP filter that:
|
||||
- Redacts CNIC patterns (12345-6789012-3)
|
||||
- Redacts phone numbers (+923001234567)
|
||||
- Redacts email addresses
|
||||
- Detects prompt injections ("ignore policy", "bypass checks", etc.)
|
||||
- Adds security warnings to flagged content
|
||||
|
||||
## Configuration Files
|
||||
|
||||
### config.yaml (Plano Configuration)
|
||||
|
||||
- **Agents**: `risk_crew_agent` with rich description for routing
|
||||
- **Filters**: `pii_security_filter` in filter chain
|
||||
- **Model Providers**: OpenAI GPT-4o and GPT-4o-mini
|
||||
- **Model Aliases**: `risk_fast` (mini), `risk_reasoning` (4o)
|
||||
- **Prompt Targets**: `create_risk_case` → Case Service API
|
||||
- **Listeners**: agent (8001), model (12000), prompt (10000)
|
||||
- **Tracing**: 100% sampling to Jaeger
|
||||
|
||||
### docker-compose.yaml
|
||||
|
||||
Orchestrates 5 services:
|
||||
- `risk-crew-agent` - Risk assessment engine
|
||||
- `case-service` - Case management
|
||||
- `pii-filter` - Security filter
|
||||
- `streamlit-ui` - Web interface
|
||||
- `jaeger` - Tracing backend
|
||||
|
||||
## Observability
|
||||
|
||||
### Jaeger Tracing
|
||||
|
||||
View distributed traces at http://localhost:16686
|
||||
|
||||
Trace flow:
|
||||
1. UI sends request to Plano
|
||||
2. Plano applies PII filter
|
||||
3. Plano routes to Risk Crew Agent
|
||||
4. Agent calls Plano LLM Gateway
|
||||
5. Agent returns assessment
|
||||
6. (Optional) Prompt target calls Case Service
|
||||
|
||||
Search for:
|
||||
- Service: `risk-crew-agent`
|
||||
- Operation: `chat_completions`
|
||||
- Tags: `request_id`, `risk_band`, `recommended_action`

## Development
|
||||
|
||||
### Running Services Individually
|
||||
|
||||
```bash
|
||||
# Risk Crew Agent
|
||||
uv run python src/credit_risk_demo/risk_crew_agent.py
|
||||
|
||||
# Case Service
|
||||
uv run python src/credit_risk_demo/case_service.py
|
||||
|
||||
# PII Filter
|
||||
uv run python src/credit_risk_demo/pii_filter.py
|
||||
|
||||
# Streamlit UI
|
||||
uv run streamlit run src/credit_risk_demo/ui_streamlit.py
|
||||
```
|
||||
|
||||
### Installing Dependencies Locally
|
||||
|
||||
```bash
|
||||
uv sync
|
||||
# or
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Services won't start**
|
||||
- Check Docker is running: `docker ps`
|
||||
- Verify ports are available: `lsof -i :8001,10530,10540,10550,8501,16686`
|
||||
- Check logs: `docker compose logs -f`
|
||||
|
||||
**Plano won't start**
|
||||
- Verify installation: `planoai --version`
|
||||
- Check config: `planoai validate config.yaml`
|
||||
- Ensure OPENAI_API_KEY is set
|
||||
|
||||
**No response from agents**
|
||||
- Verify all services are healthy:
|
||||
- `curl http://localhost:10530/health`
|
||||
- `curl http://localhost:10540/health`
|
||||
- `curl http://localhost:10550/health`
|
||||
- Check Plano is running: `curl http://localhost:8001/health` (if health endpoint exists)
|
||||
|
||||
**Streamlit can't connect**
|
||||
- Verify PLANO_ENDPOINT in docker-compose matches Plano port
|
||||
- Check `host.docker.internal` resolves (should point to host machine)
|
||||
|
||||
**Jaeger shows no traces**
|
||||
- Verify OTLP_ENDPOINT in services points to Jaeger
|
||||
- Check Jaeger is running: `docker compose ps jaeger`
|
||||
- Allow a few seconds for traces to appear
|
||||
|
||||
## API Endpoints
|
||||
|
||||
### Plano Orchestrator (8001)
|
||||
- `POST /v1/chat/completions` - Main entry point (OpenAI-compatible)
|
||||
|
||||
### Risk Crew Agent (10530)
|
||||
- `POST /v1/chat/completions` - Risk assessment endpoint
|
||||
- `GET /health` - Health check
|
||||

||||
### Case Service (10540)
|
||||
- `POST /cases` - Create case
|
||||
- `GET /cases/{case_id}` - Get case
|
||||
- `GET /cases` - List cases
|
||||
- `GET /health` - Health check
|
||||

||||
### PII Filter (10550)
|
||||
- `POST /v1/tools/pii_security_filter` - MCP filter endpoint
|
||||
- `GET /health` - Health check
|
||||
|
||||
## Next Steps
|
||||
|
||||
- Add database persistence for case storage (PostgreSQL)
|
||||
- Implement full CrewAI integration with actual agent execution
|
||||
- Add more sophisticated risk models and policy rules
|
||||
- Connect to real credit bureau APIs
|
||||
- Implement user authentication and RBAC
|
||||
- Add email notifications for case creation
|
||||
- Build analytics dashboard for risk metrics
