# Credit Risk Case Copilot
|
||||
|
||||
A small demo that follows the two-loop model: Plano is the **outer loop** (routing, guardrails, tracing), and each credit-risk step is a focused **inner-loop agent**.
|
||||
|
||||
---
|
||||
|
||||
## What runs
|
||||
|
||||
- **Risk Crew Agent (10530)**: four OpenAI-compatible endpoints (intake, risk, policy, memo).
|
||||
- **PII Filter (10550)**: redacts PII and flags prompt injection.
|
||||
- **Streamlit UI (8501)**: single-call client.
|
||||
- **Jaeger (16686)**: tracing backend.
|
||||
|
||||
---
|
||||
|
||||
## Quick start
|
||||
|
||||
```bash
|
||||
cp .env.example .env
|
||||
# add OPENAI_API_KEY
|
||||
docker compose up --build
|
||||
uvx planoai up config.yaml
|
||||
```
|
||||
|
||||
Open:
|
||||
- Streamlit UI: http://localhost:8501
|
||||
- Jaeger: http://localhost:16686
|
||||
|
||||
---
|
||||
|
||||
## How it works
|
||||
|
||||
1. The UI sends **one** request to Plano with the application JSON.
|
||||
2. Plano routes the request across the four agents in order:
|
||||
intake → risk → policy → memo.
|
||||
3. Each agent returns JSON with a `step` key.
|
||||
4. The memo agent returns the final response.
|
||||
|
||||
All model calls go through Plano’s LLM gateway, and guardrails run before any agent sees input.
|
||||
|
||||
---
|
||||
|
||||
## Endpoints
|
||||
|
||||
Risk Crew Agent (10530):
|
||||
- `POST /v1/agents/intake/chat/completions`
|
||||
- `POST /v1/agents/risk/chat/completions`
|
||||
- `POST /v1/agents/policy/chat/completions`
|
||||
- `POST /v1/agents/memo/chat/completions`
|
||||
- `GET /health`
|
||||
|
||||
PII Filter (10550):
|
||||
- `POST /v1/tools/pii_security_filter`
|
||||
- `GET /health`
|
||||
|
||||
Plano (8001):
|
||||
- `POST /v1/chat/completions`
|
||||
|
||||
---
|
||||
|
||||
## UI flow
|
||||
|
||||
1. Paste or select an application JSON.
|
||||
2. Click **Assess Risk**.
|
||||
3. Review the decision memo.
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
- **No response**: confirm Plano is running and ports are free (`8001`, `10530`, `10550`, `8501`).
|
||||
- **LLM gateway errors**: check `LLM_GATEWAY_ENDPOINT=http://host.docker.internal:12000/v1`.
|
||||
- **No traces**: check Jaeger and `OTLP_ENDPOINT`.
