# ThreatHunt - Analyst-Assist Threat Hunting Platform <<<<<<< Updated upstream
# ThreatHunt
=======
# Cyber Threat Hunter
A modern threat hunting platform with integrated analyst-assist agent guidance. Analyze CSV artifact data exported from Velociraptor with AI-powered suggestions for investigation directions, analytical pivots, and hypothesis formation. A modern web application for threat hunting and security analysis, built with React frontend and Flask backend.
## Overview
ThreatHunt is a web application designed to help security analysts efficiently hunt for threats by:
- Importing CSV artifacts from Velociraptor or other sources
- Displaying data in an organized, queryable interface
- Providing AI-powered guidance through an analyst-assist agent
- Suggesting analytical directions, filters, and pivots
- Highlighting anomalies and patterns of interest
> **Agent Policy**: The analyst-assist agent provides read-only guidance only. It does not execute actions, escalate alerts, or modify data. All decisions remain with the analyst.
## Quick Start
### Docker (Recommended)
```bash
# Clone and navigate
git clone https://github.com/mblanke/ThreatHunt.git
cd ThreatHunt
# Configure provider (choose one)
cp .env.example .env
# Edit .env and set your LLM provider:
# Option 1: Online (OpenAI, etc.)
# THREAT_HUNT_AGENT_PROVIDER=online
# THREAT_HUNT_ONLINE_API_KEY=sk-your-key
# Option 2: Local (Ollama, GGML, etc.)
# THREAT_HUNT_AGENT_PROVIDER=local
# THREAT_HUNT_LOCAL_MODEL_PATH=/path/to/model
# Option 3: Networked (Internal inference service)
# THREAT_HUNT_AGENT_PROVIDER=networked
# THREAT_HUNT_NETWORKED_ENDPOINT=http://service:5000
# Start services
docker-compose up -d
# Verify
curl http://localhost:8000/api/agent/health
curl http://localhost:3000
```
Access at http://localhost:3000
### Local Development
**Backend**:
```bash
cd backend
python -m venv venv
source venv/bin/activate # Windows: venv\Scripts\activate
pip install -r requirements.txt
# Configure provider
export THREAT_HUNT_ONLINE_API_KEY=sk-your-key
# OR set another provider env var
# Run
python run.py
# API at http://localhost:8000/docs
```
**Frontend** (new terminal):
```bash
cd frontend
npm install
npm start
# App at http://localhost:3000
```
## Features ## Features

## Architecture ## Architecture
### Backend
- **Framework**: FastAPI (Python 3.11)
- **Agent Module**: Pluggable LLM provider interface
- **API**: RESTful endpoints with OpenAPI documentation
- **Structure**: Modular design with clear separation of concerns
### Frontend
- **Framework**: React 18 with TypeScript
- **Components**: Agent chat panel + analysis dashboard
- **Styling**: CSS with responsive design
- **State Management**: React hooks + Context API
### LLM Providers
Supports three provider architectures:
1. **Local**: On-device or on-prem models (GGML, Ollama, vLLM)
2. **Networked**: Shared internal inference services
3. **Online**: External hosted APIs (OpenAI, Anthropic, Google)
Auto-detection: Automatically uses the first available provider.

## API Endpoints ## Quick Start
### Agent Assistance ### Backend Setup
- **POST /api/agent/assist** - Request guidance on artifact data
- **GET /api/agent/health** - Check agent availability
See full API documentation at http://localhost:8000/docs
## Configuration
### LLM Provider Selection
Set via `THREAT_HUNT_AGENT_PROVIDER` environment variable:
```bash
# Auto-detect (tries local → networked → online)
THREAT_HUNT_AGENT_PROVIDER=auto
# Local (on-device/on-prem)
THREAT_HUNT_AGENT_PROVIDER=local
THREAT_HUNT_LOCAL_MODEL_PATH=/models/model.gguf
# Networked (internal service)
THREAT_HUNT_AGENT_PROVIDER=networked
THREAT_HUNT_NETWORKED_ENDPOINT=http://inference:5000
THREAT_HUNT_NETWORKED_KEY=api-key
# Online (hosted API)
THREAT_HUNT_AGENT_PROVIDER=online
THREAT_HUNT_ONLINE_API_KEY=sk-your-key
THREAT_HUNT_ONLINE_PROVIDER=openai
THREAT_HUNT_ONLINE_MODEL=gpt-3.5-turbo
```
### Agent Behavior
```bash
THREAT_HUNT_AGENT_MAX_TOKENS=1024
THREAT_HUNT_AGENT_REASONING=true
THREAT_HUNT_AGENT_HISTORY_LENGTH=10
THREAT_HUNT_AGENT_FILTER_SENSITIVE=true
```
See `.env.example` for all configuration options.
## Governance & Compliance
This implementation strictly follows governance principles:
- ✅ **Agents assist analysts** - No autonomous execution
- ✅ **No tool execution** - Agent provides guidance only
- ✅ **No alert escalation** - Analyst controls alerts
- ✅ **No data modification** - Read-only analysis
- ✅ **Transparent reasoning** - Explains guidance with caveats
- ✅ **Analyst authority** - All decisions remain with analyst
**References**:
- `goose-core/governance/AGENT_POLICY.md`
- `goose-core/governance/AI_RULES.md`
- `THREATHUNT_INTENT.md`
## Documentation
- **[AGENT_IMPLEMENTATION.md](AGENT_IMPLEMENTATION.md)** - Detailed technical architecture
- **[INTEGRATION_GUIDE.md](INTEGRATION_GUIDE.md)** - Deployment and configuration
- **[IMPLEMENTATION_SUMMARY.md](IMPLEMENTATION_SUMMARY.md)** - Feature overview
## Testing the Agent
### Check Health
```bash
curl http://localhost:8000/api/agent/health
```
### Test API
```bash
curl -X POST http://localhost:8000/api/agent/assist \
-H "Content-Type: application/json" \
-d '{
"query": "What patterns suggest suspicious activity?",
"dataset_name": "FileList",
"artifact_type": "FileList",
"host_identifier": "DESKTOP-ABC123"
}'
```
### Use UI
1. Open http://localhost:3000
2. Enter a question in the agent panel
3. View guidance with suggested pivots and filters
## Troubleshooting
### Agent Unavailable (503)
- Check environment variables for provider configuration
- Verify LLM provider is accessible
- See logs: `docker-compose logs backend`
### No Frontend Response
- Verify backend health: `curl http://localhost:8000/api/agent/health`
- Check browser console for errors
- See logs: `docker-compose logs frontend`
See [INTEGRATION_GUIDE.md](INTEGRATION_GUIDE.md) for detailed troubleshooting.
## Development
### Running Tests
```bash
cd backend
pytest
cd ../frontend
npm test
```
### Building Images
```bash
docker-compose build

- Node.js 18+ (for local development)
### Quick Start with Docker
1. Clone the repository:
```bash
git clone https://github.com/mblanke/ThreatHunt.git
cd ThreatHunt
```
2. Start all services:
```bash
docker-compose up -d
```
3. Access the application:
- Frontend: http://localhost:3000
- Backend API: http://localhost:8000
- API Documentation: http://localhost:8000/docs
### Local Development
#### Backend
```bash ```bash
cd backend cd backend
python -m venv venv chmod +x setup_backend.sh
source venv/bin/activate # On Windows: venv\Scripts\activate ./setup_backend.sh
pip install -r requirements.txt source venv/bin/activate
python app.py
# Set up environment variables
cp .env.example .env
# Edit .env with your settings
# Run migrations
alembic upgrade head
# Start development server
uvicorn app.main:app --reload
``` ```
#### Frontend ### Frontend Setup
```bash ```bash
cd frontend cd frontend
npm install npm install
npm start npm run dev
``` ```
## API Endpoints ## API Endpoints
### Authentication - `GET /` - Serve React app
- `POST /api/auth/register` - Register a new user - `GET /api/health` - Health check
- `POST /api/auth/login` - Login and receive JWT token - `POST /api/upload` - File upload
- `GET /api/auth/me` - Get current user profile - `GET /api/analysis/<id>` - Get analysis results
- `PUT /api/auth/me` - Update current user profile
### User Management (Admin only) ## Security Considerations
- `GET /api/users` - List all users in tenant
- `GET /api/users/{user_id}` - Get user by ID
- `PUT /api/users/{user_id}` - Update user
- `DELETE /api/users/{user_id}` - Deactivate user
### Tenants - File upload validation
- `GET /api/tenants` - List tenants - Input sanitization
- `POST /api/tenants` - Create tenant (admin) - Rate limiting
- `GET /api/tenants/{tenant_id}` - Get tenant by ID - CORS configuration
### Hosts
- `GET /api/hosts` - List hosts (scoped to tenant)
- `POST /api/hosts` - Create host
- `GET /api/hosts/{host_id}` - Get host by ID
### Ingestion
- `POST /api/ingestion/ingest` - Upload and parse CSV files exported from Velociraptor
### VirusTotal
- `POST /api/vt/lookup` - Lookup hash in VirusTotal
## Authentication Flow
1. User registers or logs in via `/api/auth/login`
2. Backend returns JWT token with user_id, tenant_id, and role
3. Frontend stores token in localStorage
4. All subsequent API requests include token in Authorization header
5. Backend validates token and enforces tenant scoping
## Multi-Tenancy
- All data is scoped to tenant_id
- Users can only access data within their tenant
- Admin users have elevated permissions within their tenant
- Cross-tenant access requires explicit permissions
## Database Migrations
Create a new migration:
```bash
cd backend
alembic revision --autogenerate -m "Description of changes"
```
Apply migrations:
```bash
alembic upgrade head
```
Rollback migrations:
```bash
alembic downgrade -1
```
## Environment Variables
### Backend
- `DATABASE_URL` - PostgreSQL connection string
- `SECRET_KEY` - Secret key for JWT signing (min 32 characters)
- `ACCESS_TOKEN_EXPIRE_MINUTES` - JWT token expiration time (default: 30)
- `VT_API_KEY` - VirusTotal API key for hash lookups
### Frontend
- `REACT_APP_API_URL` - Backend API URL (default: http://localhost:8000)
## Security
- Passwords are hashed using bcrypt
- JWT tokens include expiration time
- All API endpoints (except login/register) require authentication
- Role-based access control for admin operations
- Data isolation through tenant scoping
## Testing
### Backend
```bash
cd backend
pytest
```
### Frontend
```bash
cd frontend
npm test
```

# Operating Model
## Default cadence
- Prefer iterative progress over big bangs.
- Keep diffs small: target ≤ 300 changed lines per PR unless justified.
- Update tests/docs as part of the same change when possible.
## Working agreement
- Start with a PLAN for non-trivial tasks.
- Implement the smallest slice that satisfies acceptance criteria.
- Verify via DoD.
- Write a crisp PR summary: what changed, why, and how verified.
## Stop conditions (plan first)
Stop and produce a PLAN (do not code yet) if:
- scope is unclear
- more than 3 files will change
- data model changes
- auth/security boundaries
- performance-critical paths

# Agent Types & Roles (Practical Taxonomy)
Use this skill to choose the *right* kind of agent workflow for the job.
## Common agent "types" (in practice)
### 1) Chat assistant (no tools)
Best for: explanations, brainstorming, small edits.
Risk: can hallucinate; no grounding in repo state.
### 2) Tool-using single agent
Best for: well-scoped tasks where the agent can read/write files and run commands.
Key control: strict DoD gates + minimal permissions.
### 3) Planner + Executor (2-role pattern)
Best for: medium complexity work (multi-file changes, feature work).
Flow: Planner writes plan + acceptance criteria → Executor implements → Reviewer checks.
### 4) Multi-agent (specialists)
Best for: bigger features with separable workstreams (UI, backend, docs, tests).
Rule: isolate context per role; use separate branches/worktrees.
### 5) Supervisor / orchestrator
Best for: long-running workflows with checkpoints (pipelines, report generation, PAD docs).
Rule: supervisor delegates, enforces gates, and composes final output.
## Decision rules (fast)
- If you can describe it in ≤ 5 steps → single tool-using agent.
- If you need tradeoffs/design → Planner + Executor.
- If UI + backend + docs/tests all move → multi-agent specialists.
- If it's a pipeline that runs repeatedly → orchestrator.
## Guardrails (always)
- DoD is the truth gate.
- Separate branches/worktrees for parallel work.
- Log decisions + commands in AGENT_LOG.md.

# Algorithms & Performance
Use this skill when performance matters (large inputs, hot paths, or repeated calls).
## Checklist
- Identify the **state** you're recomputing.
- Add **memoization / caching** when the same subproblem repeats.
- Prefer **linear scans** + caches over nested loops when possible.
- If you can write it as a **recurrence**, you can test it.
## Practical heuristics
- Measure first when possible (timing + input sizes).
- Optimize the biggest wins: avoid repeated I/O, repeated parsing, repeated network calls.
- Keep caches bounded (size/TTL) and invalidate safely.
- Choose data structures intentionally: dict/set for membership, heap for top-k, deque for queues.
## Review notes (for PRs)
- Call out accidental O(n²) patterns.
- Suggest table/DP or memoization when repeated work is obvious.
- Add tests that cover base cases + typical cases + worst-case size.

# Vibe Coding With Fundamentals (Safety Rails)
Use this skill when you're using "vibe coding" (fast, conversational building) but want production-grade outcomes.
## The good
- Rapid scaffolding and iteration
- Fast UI prototypes
- Quick exploration of architectures and options
## The failure mode
- "It works on my machine" code with weak tests
- Security foot-guns (auth, input validation, secrets)
- Performance cliffs (accidental O(n²), repeated I/O)
- Unmaintainable abstractions
## Safety rails (apply every time)
- Always start with acceptance criteria (what "done" means).
- Prefer small PRs; never dump a huge AI diff.
- Require DoD gates (lint/test/build) before merge.
- Write tests for behavior changes.
- For anything security/data related: do a Reviewer pass.
## When to slow down
- Auth/session/token work
- Anything touching payments, PII, secrets
- Data migrations/schema changes
- Performance-critical paths
- "It's flaky" or "it only fails in CI"
## Practical prompt pattern (use in PLAN)
- "State assumptions, list files to touch, propose tests, and include rollback steps."

# Performance Profiling (Bun/Node)
Use this skill when:
- a hot path feels slow
- CPU usage is high
- you suspect accidental O(n²) or repeated work
- you need evidence before optimizing
## Bun CPU profiling
Bun supports CPU profiling via `--cpu-prof` (generates a `.cpuprofile` you can open in Chrome DevTools).
Upcoming: `bun --cpu-prof-md <script>` outputs a CPU profile as **Markdown** so LLMs can read/grep it easily.
### Workflow (Bun)
1) Run the workload with profiling enabled
- Today: `bun --cpu-prof ./path/to/script.ts`
- Upcoming: `bun --cpu-prof-md ./path/to/script.ts`
2) Save the output (or `.cpuprofile`) into `./profiles/` with a timestamp.
3) Ask the Reviewer agent to:
- identify the top 5 hottest functions
- propose the smallest fix
- add a regression test or benchmark
## Node CPU profiling (fallback)
- `node --cpu-prof ./script.js` writes a `.cpuprofile` file.
- Open in Chrome DevTools → Performance → Load profile.
## Rules
- Optimize based on measured hotspots, not vibes.
- Prefer algorithmic wins (remove repeated work) over micro-optimizations.
- Keep profiling artifacts out of git unless explicitly needed (use `.gitignore`).

# Implementation Rules
## Change policy
- Prefer edits over rewrites.
- Keep changes localized.
- One change = one purpose.
- Avoid unnecessary abstraction.
## Dependency policy
- Default: do not add dependencies.
- If adding: explain why, alternatives considered, and impact.
## Error handling
- Validate inputs at boundaries.
- Error messages must be actionable: what failed + what to do next.

# Testing & Quality
## Strategy
- If behavior changes: add/update tests.
- Unit tests for logic; integration tests for boundaries; E2E only where needed.
## Minimum for every PR
- A test plan in the PR summary (even if "existing tests cover this").
- Run DoD.
## Flaky tests
- Capture repro steps.
- Quarantine only with justification + follow-up issue.

# PR Review Skill
Reviewer must check:
- Correctness: does it do what it claims?
- Safety: secrets, injection, auth boundaries
- Maintainability: readability, naming, duplication
- Tests: added/updated appropriately
- DoD: did it pass?
Reviewer output format:
1) Summary
2) Must-fix
3) Nice-to-have
4) Risks

# Material UI (MUI) Design System
Use this skill for any React/Next "portal/admin/dashboard" UI so you stay consistent and avoid random component soup.
## Standard choice
- Preferred UI library: **MUI (Material UI)**.
- Prefer MUI components over ad-hoc HTML/CSS unless there's a good reason.
- One design system per repo (do not mix Chakra/Ant/Bootstrap/etc.).
## Setup (Next.js/React)
- Install: `@mui/material @emotion/react @emotion/styled`
- If using icons: `@mui/icons-material`
- If using data grid: `@mui/x-data-grid` (or pro if licensed)
## Theming rules
- Define a single theme (typography, spacing, palette) and reuse everywhere.
- Use semantic colors (primary/secondary/error/warning/success/info), not hard-coded hex everywhere.
- Prefer MUI's `sx` for small styling; use `styled()` for reusable components.
## "Portal" patterns (modals, popovers, menus)
- Use MUI Dialog/Modal/Popover/Menu components instead of DIY portals.
- Accessibility requirements:
- Focus is trapped in Dialog/Modal.
- Escape closes modal unless explicitly prevented.
- All inputs have labels; buttons have clear text/aria-labels.
- Keyboard navigation works end-to-end.
## Layout conventions (for portals)
- Use: AppBar + Drawer (or NavigationRail equivalent) + main content.
- Keep pages as composition of small components: Page → Sections → Widgets.
- Keep forms consistent: FormControl + helper text + validation messages.
## Performance hygiene
- Avoid re-render storms: memoize heavy lists; use virtualization for large tables (DataGrid).
- Prefer server pagination for huge datasets.
## PR review checklist
- Theme is used (no random styling).
- Components are MUI where reasonable.
- Modal/popover accessibility is correct.
- No mixed UI libraries.

# MCP Tools Skill (Optional)
If this repo defines MCP servers/tools:
Rules:
- Tool calls must be explicit and logged.
- Maintain an allowlist of tools; deny by default.
- Every tool must have: purpose, inputs/outputs schema, examples, and tests.
- Prefer idempotent tool operations.
- Never add tools that can exfiltrate secrets without strict guards.

# MCP Server Design (Agent-First)
Build MCP servers like you're designing a UI for a non-human user.
This skill distills Phil Schmid's MCP server best practices into concrete repo rules.
Source: "MCP is Not the Problem, It's your Server" (Jan 21, 2026).
## 1) Outcomes, not operations
- Do **not** wrap REST endpoints 1:1 as tools.
- Expose high-level, outcome-oriented tools.
- Bad: `get_user`, `list_orders`, `get_order_status`
- Good: `track_latest_order(email)` (server orchestrates internally)
## 2) Flatten arguments
- Prefer top-level primitives + constrained enums.
- Avoid nested `dict`/config objects (agents hallucinate keys).
- Defaults reduce decision load.
## 3) Instructions are context
- Tool docstrings are *instructions*:
- when to use the tool
- argument formatting rules
- what the return means
- Error strings are also context:
- return actionable, self-correcting messages (not raw stack traces)
## 4) Curate ruthlessly
- Aim for **5–15 tools** per server.
- One server, one job. Split by persona if needed.
- Delete unused tools. Don't dump raw data into context.
## 5) Name tools for discovery
- Avoid generic names (`create_issue`).
- Prefer `{service}_{action}_{resource}`:
- `velociraptor_run_hunt`
- `github_list_prs`
- `slack_send_message`
## 6) Paginate large results
- Always support `limit` (default ~20–50).
- Return metadata: `has_more`, `next_offset`, `total_count`.
- Never return hundreds of rows unbounded.
## Repo conventions
- Put MCP tool specs in `mcp/` (schemas, examples, fixtures).
- Provide at least 1 "golden path" example call per tool.
- Add an eval that checks:
- tool names follow discovery convention
- args are flat + typed
- responses are concise + stable
- pagination works

# FastMCP 3 Patterns (Providers + Transforms)
Use this skill when you are building MCP servers in Python and want:
- composable tool sets
- per-user/per-session behavior
- auth, versioning, observability, and long-running tasks
## Mental model (FastMCP 3)
FastMCP 3 treats everything as three composable primitives:
- **Components**: what you expose (tools, resources, prompts)
- **Providers**: where components come from (decorators, files, OpenAPI, remote MCP, etc.)
- **Transforms**: how you reshape what clients see (namespace, filters, auth, versioning, visibility)
## Recommended architecture for Marc's platform
Build a **single "Cyber MCP Gateway"** that composes providers:
- LocalProvider: core cyber tools (run hunt, parse triage, generate report)
- OpenAPIProvider: wrap stable internal APIs (ticketing, asset DB) without 1:1 endpoint exposure
- ProxyProvider/FastMCPProvider: mount sub-servers (e.g., Velociraptor tools, Intel feeds)
Then apply transforms:
- Namespace per domain: `hunt.*`, `intel.*`, `pad.*`
- Visibility per session: hide dangerous tools unless user/role allows
- VersionFilter: keep old clients working while you evolve tools
## Production must-haves
- **Tool timeouts**: never let a tool hang forever
- **Pagination**: all list tools must be bounded
- **Background tasks**: use for long hunts / ingest jobs
- **Tracing**: emit OpenTelemetry traces so you can debug agent/tool behavior
## Auth rules
- Prefer component-level auth for "dangerous" tools.
- Default stance: read-only tools visible; write/execute tools gated.
## Versioning rules
- Version your components when you change schemas or semantics.
- Keep 1 previous version callable during migrations.
## Upgrade guidance
FastMCP 3 is in beta; pin to v2 for stability in production until you've tested.

# ThreatHunt Analyst-Assist Agent Implementation
## Overview
This implementation adds an analyst-assist agent to ThreatHunt that provides read-only guidance on CSV artifact data, analytical pivots, and hypotheses. The agent strictly adheres to the governance principles defined in `goose-core/governance/AGENT_POLICY.md`.
## Architecture
### Backend Stack
- **Framework**: FastAPI (Python 3.11)
- **Agent Module**: `backend/app/agents/`
- `core.py`: ThreatHuntAgent class with guidance logic
- `providers.py`: Pluggable LLM provider interface
- `config.py`: Configuration management
### Frontend Stack
- **Framework**: React with TypeScript
- **Components**: AgentPanel chat interface
- **Styling**: CSS with responsive design
### API Endpoint
- **POST /api/agent/assist**: Request analyst guidance
- **GET /api/agent/health**: Check agent availability
## LLM Provider Architecture
The agent supports three provider types, selectable via configuration:
### 1. Local Provider
**Use Case**: On-device or on-premise models
Environment variables:
```bash
THREAT_HUNT_AGENT_PROVIDER=local
THREAT_HUNT_LOCAL_MODEL_PATH=/path/to/model.gguf
```
Supported frameworks:
- llama-cpp-python (GGML models)
- Ollama API
- vLLM
- Other local inference engines
### 2. Networked Provider
**Use Case**: Shared internal inference services
Environment variables:
```bash
THREAT_HUNT_AGENT_PROVIDER=networked
THREAT_HUNT_NETWORKED_ENDPOINT=http://inference-service:5000
THREAT_HUNT_NETWORKED_KEY=api-key-here
```
Supported architectures:
- Internal inference service API
- LLM inference container clusters
- Enterprise inference gateways
### 3. Online Provider
**Use Case**: External hosted APIs
Environment variables:
```bash
THREAT_HUNT_AGENT_PROVIDER=online
THREAT_HUNT_ONLINE_API_KEY=sk-your-api-key
THREAT_HUNT_ONLINE_PROVIDER=openai
THREAT_HUNT_ONLINE_MODEL=gpt-3.5-turbo
```
Supported providers:
- OpenAI (GPT-3.5, GPT-4)
- Anthropic Claude
- Google Gemini
- Other hosted LLM services
### Auto Provider Selection
Set `THREAT_HUNT_AGENT_PROVIDER=auto` to automatically use the first available provider:
1. Local (if model path exists)
2. Networked (if endpoint is configured)
3. Online (if API key is set)
## Backend Implementation
### Agent Request/Response Flow
**Request** (AgentContext):
```python
{
"query": "What patterns suggest suspicious file modifications?",
"dataset_name": "FileList-2025-12-26",
"artifact_type": "FileList",
"host_identifier": "DESKTOP-ABC123",
"data_summary": "File listing from system scan",
"conversation_history": [...]
}
```
**Response** (AgentResponse):
```python
{
"guidance": "Based on the files listed, ...",
"confidence": 0.8,
"suggested_pivots": ["Analyze temporal patterns", "Cross-reference with IOCs"],
"suggested_filters": ["Filter by modification time", "Sort by file size"],
"caveats": "Guidance is based on available data context...",
"reasoning": "Analysis generated based on patterns..."
}
```
### Governance Enforcement
The agent is designed with hard constraints to ensure compliance:
1. **Read-Only**: Agent accepts context data but cannot:
- Execute tools or actions
- Modify database or schema
- Escalate findings to alerts
- Access external systems
2. **Advisory Only**: All guidance is clearly marked as:
- Suggestions, not directives
- Confidence-rated
- Accompanied by caveats
- Attributed to the agent
3. **Analyst Control**: The UI emphasizes:
- Agent provides guidance only
- Analysts retain all decision-making authority
- All next steps require analyst action
## Frontend Implementation
### AgentPanel Component
Located in `frontend/src/components/AgentPanel.tsx`:
**Features**:
- Chat-style interface for analyst questions
- Context display showing current dataset/host/artifact
- Rich response formatting with:
- Main guidance text
- Suggested analytical pivots (clickable)
- Suggested data filters
- Confidence scores
- Caveats and assumptions
- Reasoning explanation
- Conversation history for context
- Responsive design (desktop and mobile)
- Loading states and error handling
**Props**:
```typescript
interface AgentPanelProps {
dataset_name?: string;
artifact_type?: string;
host_identifier?: string;
data_summary?: string;
onAnalysisAction?: (action: string) => void;
}
```
### Integration in Main UI
The agent panel is integrated into the main ThreatHunt dashboard as a sidebar component. In `App.tsx`:
1. Main analysis view occupies left side
2. Agent panel occupies right sidebar
3. Context automatically updated when analyst switches datasets/hosts
4. Responsive layout: stacks vertically on mobile
## Configuration
### Environment Variables
```bash
# Provider selection
THREAT_HUNT_AGENT_PROVIDER=auto # auto, local, networked, or online
# Local provider
THREAT_HUNT_LOCAL_MODEL_PATH=/models/model.gguf
# Networked provider
THREAT_HUNT_NETWORKED_ENDPOINT=http://service:5000
THREAT_HUNT_NETWORKED_KEY=api-key
# Online provider
THREAT_HUNT_ONLINE_API_KEY=sk-key
THREAT_HUNT_ONLINE_PROVIDER=openai
THREAT_HUNT_ONLINE_MODEL=gpt-3.5-turbo
# Agent behavior
THREAT_HUNT_AGENT_MAX_TOKENS=1024
THREAT_HUNT_AGENT_REASONING=true
THREAT_HUNT_AGENT_HISTORY_LENGTH=10
THREAT_HUNT_AGENT_FILTER_SENSITIVE=true
# Frontend
REACT_APP_API_URL=http://localhost:8000
```
### Docker Deployment
Use `docker-compose.yml` for full stack deployment:
```bash
# Build and start services
docker-compose up -d
# Verify health
curl http://localhost:8000/api/agent/health
curl http://localhost:3000
# View logs
docker-compose logs -f backend
docker-compose logs -f frontend
# Stop services
docker-compose down
```
## Security Considerations
1. **API Access**: Backend should be protected with authentication in production
2. **LLM Privacy**: Sensitive data (IPs, usernames) should be filtered before sending to online providers
3. **Error Messages**: Production should use generic error messages, not expose internal details
4. **Rate Limiting**: Implement rate limiting on agent endpoints
5. **Conversation History**: Consider data retention policies for conversation logs
## Testing
### Manual Testing
1. **Agent Health**:
```bash
curl http://localhost:8000/api/agent/health
```
2. **Agent Assistance** (without frontend):
```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",
"artifact_type": "FileList",
"host_identifier": "HOST123"
}'
```
3. **Frontend UI**:
- Navigate to http://localhost:3000
- Type question in agent panel
- Verify response displays correctly
## Future Enhancements
1. **Structured Output**: Use LLM JSON mode or function calling for more reliable parsing
2. **Context Filtering**: Automatically filter sensitive data before sending to LLM
3. **Multi-Modal**: Support image uploads (binary analysis, network diagrams)
4. **Caching**: Cache common agent responses to reduce latency
5. **Feedback Loop**: Capture analyst feedback on guidance quality
6. **Integration**: Connect agent to actual CVE databases, threat feeds
7. **Custom Models**: Support fine-tuned models for threat hunting domain
8. **Audit Trail**: Comprehensive logging of all agent interactions
## Governance Compliance
This implementation strictly follows:
- `goose-core/governance/AGENT_POLICY.md` - Agent boundaries and allowed functions
- `goose-core/governance/AI_RULES.md` - AI system rules
- `goose-core/governance/SCOPE.md` - Shared vs application-specific responsibility
- `ThreatHunt/THREATHUNT_INTENT.md` - Agent role in threat hunting
**Key Principles**:
- ✅ Agents assist analysts, never act autonomously
- ✅ No execution without explicit analyst approval
- ✅ No database or schema changes
- ✅ No alert escalation
- ✅ Read-only guidance
- ✅ Transparent reasoning and caveats
- ✅ Analyst retains all authority
## Troubleshooting
### Agent Unavailable (503)
- Check environment variables for provider configuration
- Verify LLM provider is accessible
- Review backend logs: `docker-compose logs backend`
### Slow Responses
- Check LLM provider latency
- Reduce MAX_TOKENS if appropriate
- Consider local provider for latency-sensitive deployments
### No Responses from Frontend
- Verify backend health: `curl http://localhost:8000/api/agent/health`
- Check browser console for errors
- Verify REACT_APP_API_URL in frontend environment
- Check CORS configuration if frontend hosted separately

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..."
}
```

# Analyst-Assist Agent Implementation Summary
## Completed Implementation
I've successfully implemented a full analyst-assist agent for ThreatHunt following all governance principles from goose-core.
## What Was Built
### Backend (Python/FastAPI)
✅ **Agent Module** (`backend/app/agents/`)
- `core.py`: ThreatHuntAgent class with guidance logic
- `providers.py`: Pluggable LLM provider interface (local, networked, online)
- `config.py`: Environment-based configuration management
✅ **API Endpoint** (`backend/app/api/routes/agent.py`)
- POST `/api/agent/assist`: Request guidance with context
- GET `/api/agent/health`: Check agent availability
✅ **Application Structure**
- `main.py`: FastAPI application with CORS
- `requirements.txt`: Dependencies (FastAPI, Uvicorn, Pydantic)
- `run.py`: Entry point for local development
### Frontend (React/TypeScript)
✅ **Agent Chat Component** (`frontend/src/components/AgentPanel.tsx`)
- Chat-style interface for analyst questions
- Context display (dataset, host, artifact)
- Rich response formatting with pivots, filters, caveats
- Conversation history support
- Responsive design
✅ **API Integration** (`frontend/src/utils/agentApi.ts`)
- Type-safe request/response definitions
- Health check functionality
- Error handling
✅ **Main Application**
- `App.tsx`: Dashboard with agent panel in sidebar
- `App.css`: Responsive layout (desktop/mobile)
- `index.tsx`, `index.html`: React setup
✅ **Configuration**
- `package.json`: Dependencies (React 18, TypeScript)
- `tsconfig.json`: TypeScript configuration
### Docker & Deployment
✅ **Containerization**
- `Dockerfile.backend`: Python 3.11 FastAPI container
- `Dockerfile.frontend`: Node 18 React production build
- `docker-compose.yml`: Full stack with networking
- `.env.example`: Configuration template
## LLM Provider Architecture
### Three Pluggable Providers
**1. Local Provider**
```bash
THREAT_HUNT_AGENT_PROVIDER=local
THREAT_HUNT_LOCAL_MODEL_PATH=/path/to/model.gguf
```
- On-device or on-prem models
- GGML, Ollama, vLLM, etc.
**2. Networked Provider**
```bash
THREAT_HUNT_AGENT_PROVIDER=networked
THREAT_HUNT_NETWORKED_ENDPOINT=http://service:5000
THREAT_HUNT_NETWORKED_KEY=api-key
```
- Shared internal inference services
- Enterprise inference gateways
**3. Online Provider**
```bash
THREAT_HUNT_AGENT_PROVIDER=online
THREAT_HUNT_ONLINE_API_KEY=sk-key
THREAT_HUNT_ONLINE_PROVIDER=openai
THREAT_HUNT_ONLINE_MODEL=gpt-3.5-turbo
```
- OpenAI, Anthropic, Google, etc.
**Auto Selection**
```bash
THREAT_HUNT_AGENT_PROVIDER=auto
```
- Tries: local → networked → online
## Governance Compliance
✅ **Strict Policy Adherence**
- No autonomous execution (agents advise only)
- No tool execution (read-only guidance)
- No database/schema changes
- No alert escalation
- Transparent reasoning with caveats
- Analyst retains all authority
✅ **follows AGENT_POLICY.md**
- Agents guide, explain, suggest
- Agents do NOT execute, escalate, or modify data
- All output is advisory and attributable
✅ **Follows THREATHUNT_INTENT.md**
- Helps interpret artifact data
- Suggests analytical pivots and filters
- Highlights anomalies
- Assists in hypothesis formation
- Does NOT perform analysis independently
## API Specifications

## Key Design Decisions
1. **Pluggable Providers**: Support multiple LLM backends without changing application code
2. **Auto-Detection**: Smart provider selection for deployment flexibility
3. **Context-Aware**: Agent requests include dataset, host, and artifact context
4. **Read-Only**: Hard constraints prevent agent from executing, modifying, or escalating
5. **Advisory UI**: Frontend emphasizes guidance-only nature with caveats and disclaimers
6. **Conversation History**: Maintains context across multiple analyst queries
7. **Error Handling**: Graceful degradation if LLM provider unavailable
8. **Containerized**: Full Docker support for easy deployment and scaling
## Next Steps / Future Enhancements
1. **Integration Testing**: Add pytest/vitest test suites
2. **Authentication**: Add JWT/OAuth to API endpoints
3. **Rate Limiting**: Implement request throttling
4. **Structured Output**: Use LLM JSON mode or function calling
5. **Data Filtering**: Auto-filter sensitive data before LLM
6. **Caching**: Cache common agent responses
7. **Feedback Loop**: Capture guidance quality feedback from analysts
8. **Audit Trail**: Comprehensive logging and compliance reporting
9. **Fine-tuning**: Custom models for cybersecurity domain
10. **Performance**: Optimize latency and throughput
## Governance References
This implementation fully complies with:
- ✅ `goose-core/governance/AGENT_POLICY.md`
- ✅ `goose-core/governance/AI_RULES.md`
- ✅ `goose-core/governance/SCOPE.md`
- ✅ `goose-core/governance/ALERT_POLICY.md`
- ✅ `goose-core/contracts/finding.json`
- ✅ `ThreatHunt/THREATHUNT_INTENT.md`
**Core Principle**: Agents assist analysts, never act autonomously.
