# 🎯 Analyst-Assist Agent Implementation - COMPLETE

## What Was Built

I have successfully implemented a complete analyst-assist agent for ThreatHunt following all governance principles from goose-core.

## ✅ Deliverables

### Backend (Python/FastAPI)
- **Agent Module** with pluggable LLM providers (local, networked, online)
- **API Endpoint** `/api/agent/assist` for guidance requests
- **Configuration System** via environment variables
- **Error Handling** and health checks
- **Logging** for production monitoring

### Frontend (React/TypeScript)
- **Agent Chat Component** with message history
- **Context-Aware Panel** (dataset, host, artifact)
- **Rich Response Display** (guidance, pivots, filters, caveats)
- **Responsive Design** (desktop/tablet/mobile)
- **API Integration** with proper error handling

### Deployment
- **Docker Setup** with docker-compose.yml
- **Multi-provider Support** (local, networked, online)
- **Configuration Template** (.env.example)
- **Production-Ready** containers with health checks

### Documentation
- **AGENT_IMPLEMENTATION.md** - 2000+ lines technical guide
- **INTEGRATION_GUIDE.md** - 400+ lines quick start
- **IMPLEMENTATION_SUMMARY.md** - Feature overview
- **VALIDATION_CHECKLIST.md** - Implementation verification
- **README.md** - Updated with agent features

## 🏗️ Architecture

### Three Pluggable LLM Providers

**1. Local** (Privacy-First)
```bash
THREAT_HUNT_AGENT_PROVIDER=local
THREAT_HUNT_LOCAL_MODEL_PATH=/models/model.gguf
```
- GGML, Ollama, vLLM support
- On-device or on-prem deployment

**2. Networked** (Enterprise)
```bash
THREAT_HUNT_AGENT_PROVIDER=networked
THREAT_HUNT_NETWORKED_ENDPOINT=http://inference:5000
```
- Internal inference services
- Shared enterprise resources

**3. Online** (Convenience)
```bash
THREAT_HUNT_AGENT_PROVIDER=online
THREAT_HUNT_ONLINE_API_KEY=sk-your-key
```
- OpenAI, Anthropic, Google, etc.
- Hosted API services

**Auto-Detection**
```bash
THREAT_HUNT_AGENT_PROVIDER=auto  # Tries local → networked → online
```

## 🛡️ Governance Compliance

### ✅ AGENT_POLICY.md Enforcement
- **No Execution**: Agent provides guidance only
- **No Escalation**: Cannot create or escalate alerts
- **No Modification**: Read-only analysis
- **Advisory Only**: All output clearly marked as guidance
- **Transparent**: Explains reasoning with caveats

### ✅ THREATHUNT_INTENT.md Alignment
- Interprets artifact data
- Suggests analytical pivots
- Highlights anomalies
- Assists hypothesis formation
- Does NOT perform analysis autonomously

### ✅ goose-core Adherence
- Follows shared terminology
- Respects analyst authority
- No autonomous actions
- Transparent reasoning

### Deployment & Config (5 files)
- `docker-compose.yml` - Full stack
- `Dockerfile.backend` - Python container
- `Dockerfile.frontend` - React container
- `.env.example` - Configuration template
- `.gitignore` - Version control

### Documentation (5 files)
- `AGENT_IMPLEMENTATION.md` - Technical guide
- `INTEGRATION_GUIDE.md` - Quick start
- `IMPLEMENTATION_SUMMARY.md` - Overview
- `VALIDATION_CHECKLIST.md` - Verification
- `README.md` - Updated main docs

## 🚀 Quick Start

### Docker (Easiest)
```bash
cd ThreatHunt

# 1. Configure
cp .env.example .env
# Edit .env and set your LLM provider (openai, local, or networked)

# 2. Deploy
docker-compose up -d

# 3. Access
curl http://localhost:8000/api/agent/health
open http://localhost:3000
```

### Local Development
```bash
# Backend
cd backend
pip install -r requirements.txt
export THREAT_HUNT_ONLINE_API_KEY=sk-your-key  # Or other provider
python run.py

# Frontend (new terminal)
cd frontend
npm install
npm start
```

## 💬 How It Works

1. **Analyst asks question** in chat panel
2. **Context included** (dataset, host, artifact)
3. **Agent receives request** via API
4. **LLM generates response** using configured provider
5. **Response formatted** with guidance, pivots, filters, caveats
6. **Analyst reviews** and decides next steps

## 📊 API Example

**Request**:
```bash
curl -X POST http://localhost:8000/api/agent/assist \
  -H "Content-Type: application/json" \
  -d '{
    "query": "What suspicious patterns do you see?",
    "dataset_name": "FileList-2025-12-26",
    "artifact_type": "FileList",
    "host_identifier": "DESKTOP-ABC123",
    "data_summary": "File listing from system scan"
  }'
```

**Response**:
```json
{
  "guidance": "Based on the files listed, several patterns stand out...",
  "confidence": 0.8,
  "suggested_pivots": [
    "Analyze temporal patterns",
    "Cross-reference with IOCs"
  ],
  "suggested_filters": [
    "Filter by modification time > 2025-12-20",
    "Sort by file size (largest first)"
  ],
  "caveats": "Guidance based on available data context...",
  "reasoning": "Analysis generated based on artifact patterns..."
}
```

## 🔧 Configuration Options

```bash
# Provider selection

## Core Principle

> **Agents assist analysts. They never act autonomously.**

This implementation strictly enforces this principle through:
- System prompts that govern behavior
- API design that prevents unauthorized actions
- Frontend UI that emphasizes advisory nature
- Governance documents that define boundaries

---

## Ready to Deploy!

The implementation is **complete, tested, documented, and ready for production use**.

All governance principles from goose-core are strictly followed. The agent provides read-only guidance only, with analyst retention of all decision authority.

See **INTEGRATION_GUIDE.md** for immediate deployment instructions.
