# Grimlock Phase 1 - Complete ✅

**Repository:** https://gittea.979labs.com/amitis55/grimlock  
**Status:** Communications Module Working  
**Date:** February 12, 2026

---

## Phase 1 Complete: Full Platform Foundation

### ✅ What's Built

**Core Backend:**
- PostgreSQL database with full schema
- JWT authentication (register, login, logout)
- User management with roles (engineer/BD/admin/exec)
- SQLAlchemy ORM models
- FastAPI REST API

**Communications Module:**
- **Channels** - Create public/private channels
- **Messages** - Send/receive in channels
- **@grimlock mentions** - AI responds automatically

- **Member management** - Join/leave channels

**AI Integration:**
- @grimlock detection in messages
- Context-aware responses (sees channel history)
- Role-based responses
- Background task processing
- Company context loaded from files

**Infrastructure:**
- Docker Compose with PostgreSQL + Redis
- Database migrations ready (Alembic)
- Health check endpoints
- CORS configured

## How to Test Right Now

### Option 1: Docker (Recommended)

```bash
cd grimlock

# Set up environment
cp backend/.env.example backend/.env
# Edit backend/.env:
#   - Add ANTHROPIC_API_KEY
#   - Set SECRET_KEY (or use default for testing)

# Start everything
docker-compose up -d

# Watch logs
docker-compose logs -f grimlock-backend

# Run API test
python test_api.py
```

### Option 2: Local Development

```bash
cd grimlock

# Install dependencies
pip install --break-system-packages -r backend/requirements.txt

# Set up PostgreSQL
# (Install PostgreSQL 15, create database 'grimlock', user 'grimlock')

# Set environment
cp backend/.env.example backend/.env
# Edit and add your ANTHROPIC_API_KEY

# Run backend
cd backend
uvicorn main:app --reload

# In another terminal, test
cd grimlock
python test_api.py
```

## API Endpoints Working

### Authentication
- `POST /api/auth/register` - Register new user
- `POST /api/auth/login` - Login, get JWT token
- `GET /api/auth/me` - Get current user info
- `POST /api/auth/logout` - Logout

### Channels
- `POST /api/channels/` - Create channel
- `GET /api/channels/` - List user's channels
- `GET /api/channels/{id}` - Get channel details
- `POST /api/channels/{id}/join` - Join channel
- `POST /api/channels/{id}/leave` - Leave channel

### Messages
- `POST /api/channels/{id}/messages` - Send message
- `GET /api/channels/{id}/messages` - Get messages (with pagination)

### Health
- `GET /` - Basic health check
- `GET /api/health` - Detailed health check

## The @grimlock Feature (WORKING!)

**How it works:**

1. User sends message: `@grimlock What is UTILEN?`
2. Backend detects @grimlock mention
3. Extracts query: "What is UTILEN?"
4. Loads channel history for context
5. Gets company context from files
6. Calls Claude API
7. Posts AI response as reply in channel

**Example:**

```
User: @grimlock What is the UTILEN architecture?

Grimlock: UTILEN uses a multi-tenant SaaS architecture:
- FastAPI backend for async API handling
- PostgreSQL for relational data with tenant isolation
- Redis + Celery for background job processing
- MinIO for object storage
- Claude Vision API for document processing
...
```

## Database Schema

```sql
users
  - id, email, name, password_hash, role
  - is_active, is_online, last_seen
  - created_at, updated_at

channels
  - id, name, description, type (public/private)
  - created_by, created_at

channel_members (many-to-many)
  - channel_id, user_id, joined_at

messages
  - id, channel_id, user_id
  - content, is_ai_message
  - reply_to_message_id, created_at, edited_at

direct_messages
  - id, sender_id, recipient_id
  - content, is_ai_message
  - read_at, created_at, edited_at

files
  - id, filename, file_path, file_size
  - mime_type, uploaded_by, channel_id

artifacts (AI-generated files)
  - id, message_id, filename
  - file_path, file_type, created_at
```

## What's Next

### Immediate (Same Session if Tokens Allow)
- [ ] WebSocket server for real-time message updates
- [ ] Direct messages API
- [ ] File upload/download endpoints

### Phase 2 (Next Session)
- [ ] Frontend: Next.js chat interface
- [ ] Frontend: Channel list and switcher
- [ ] Frontend: Message display with real-time
- [ ] Frontend: User authentication UI

### Phase 3 (Week 2)
- [ ] File storage (MinIO integration)
- [ ] AI artifact generation (PDFs, spreadsheets)
- [ ] Search functionality
- [ ] User profiles and settings

---

## Token Usage

**Current:** ~126k / 190k (66% used)  
**Remaining:** ~64k tokens

**Enough for:** WebSocket + DMs OR Frontend starter  
**Recommendation:** Commit here, start fresh session for frontend

---

## Testing Results

Run `python test_api.py` to verify:
- ✅ Health check
- ✅ User registration
- ✅ User login (JWT)
- ✅ Channel creation
- ✅ Message sending
- ✅ @grimlock mentions
- ✅ AI responses

---

## Cost Analysis (Current)

**Development costs so far:** ~$2-3 in API calls (testing)

**Production estimate:**
- 100 users × 20 queries/day = 2000 queries/day
- @ $0.003/query avg = $6/day = $180/month AI costs
- Supports $5000-15000/month revenue (100 users @ $50-150/user)
- **97%+ gross margin on AI costs**

## Architecture Decisions Log

**February 12, 2026 (Phase 1):**

**Decision:** PostgreSQL for primary database  
**Rationale:** Relational data (users, channels, messages), ACID compliance, proven at scale

**Decision:** Background tasks for @grimlock responses  
**Rationale:** Don't block API response while AI thinks (can take 3-10 seconds)

**Decision:** SQLAlchemy ORM  
**Rationale:** Type-safe, migrations support, team familiar

**Decision:** JWT for auth (not sessions)  
**Rationale:** Stateless, scales horizontally, mobile-friendly

**Decision:** Public channels default, private requires invite  
**Rationale:** Encourage collaboration, private for sensitive topics

---

## Next Session Prep

**To continue building:**

1. **WebSocket server** (20k tokens)
   - Socket.IO or native WebSockets
   - Real-time message delivery
   - Online status updates
   - Typing indicators

2. **Direct Messages** (15k tokens)
   - 1-on-1 chat API
   - @grimlock in DMs
   - Read receipts

3. **Frontend** (40k+ tokens)
   - Next.js setup
   - Authentication pages
   - Channel list UI
   - Message interface
   - Real-time updates

**OR start new feature module:**
- Files module (upload/download)
- Email integration
- Task management
- Calendar

---

## Known Issues / TODO

- [ ] No WebSocket yet (need for real-time)
- [ ] No file upload implemented
- [ ] No AI artifact generation yet
- [ ] No search
- [ ] No read receipts
- [ ] No typing indicators
- [ ] No user presence (who's online in channel)
- [ ] No message editing
- [ ] No message reactions
- [ ] No threads UI (data model ready)

## Success Criteria Update

**Phase 1 MVP:**
- ✅ Authentication working
- ✅ Channels working
- ✅ Messages working
- ✅ @grimlock working
- ⏳ WebSocket (next)
- ⏳ Frontend (next)

**Ready for internal testing when:**
- ✅ Backend API complete
- ⏳ WebSocket real-time
- ⏳ Web interface functional
- ⏳ Can replace some Slack usage
