# AITBC CLI Enhancement Plan

## Goal
Make the AITBC project fully usable via CLI tools, covering all functionality currently available through web interfaces.

## Prerequisites

### System Requirements
- Python 3.8+ (tested on Python 3.11)
- Debian Trixie (Linux)
- Network connection for API access

### Installation Methods

#### Method 1: Development Install
```bash
cd /home/oib/windsurf/aitbc
pip install -e .
```

#### Method 2: From PyPI (future)
```bash
pip install aitbc-cli
```

#### Method 3: Using Docker
```bash
docker run -it aitbc/cli:latest
```

### Shell Completion
```bash
# Install completions
aitbc --install-completion bash  # or zsh, fish

# Enable immediately
source ~/.bashrc  # or ~/.zshrc
```

### Environment Variables
```bash
export AITBC_CONFIG_DIR="$HOME/.aitbc"
export AITBC_LOG_LEVEL="info"
export AITBC_API_KEY="${CLIENT_API_KEY}"  # Optional, can use auth login
```

## Current State Analysis

### Existing CLI Tools
1. **client.py** - Submit jobs, check status, list blocks
2. **miner.py** - Register miners, poll for jobs, submit results  
3. **wallet.py** - Track earnings, manage wallet (local only)
4. **GPU Testing Tools** - test_gpu_access.py, gpu_test.py, miner_gpu_test.py

### Infrastructure Overview (Current Setup)
- **Coordinator API**: `http://localhost:8000` (direct) or `http://127.0.0.1:18000` (via SSH tunnel)
- **Blockchain Nodes**: RPC on `http://localhost:8081` and `http://localhost:8082`
- **Wallet Daemon**: `http://localhost:8002`
- **Exchange API**: `http://localhost:9080` (if running)
- **Test Wallets**: Located in `home/` directory with separate client/miner wallets
- **Single Developer Environment**: You are the only user/developer

### Test User Setup
The `home/` directory contains simulated user wallets for testing:
- **Genesis Wallet**: 1,000,000 AITBC (creates initial supply)
- **Client Wallet**: 10,000 AITBC (customer wallet)
- **Miner Wallet**: 1,000 AITBC (GPU provider wallet)

### Critical Issues to Address

#### 1. Inconsistent Default URLs
- `client.py` uses `http://127.0.0.1:18000`
- `miner.py` uses `http://localhost:8001`
- **Action**: Standardize all to `http://localhost:8000` with fallback to tunnel

#### 2. API Key Security
- Currently stored as plaintext in environment variables
- No credential management system
- **Action**: Implement encrypted storage with keyring

#### 3. Missing Package Structure
- No `pyproject.toml` or `setup.py`
- CLI tools not installable as package
- **Action**: Create proper Python package structure

## Enhancement Plan

## Leveraging Existing Assets

### Existing Scripts to Utilize

#### 1. `scripts/aitbc-cli.sh`
- Already provides unified CLI wrapper
- Has basic commands: submit, status, blocks, receipts, admin functions
- **Action**: Extend this script or use as reference for unified CLI
- **Issue**: Uses hardcoded URL `http://127.0.0.1:18000`

#### 2. Existing `pyproject.toml`
- Already exists at project root
- Configured for pytest with proper paths
- **Action**: Add CLI package configuration and entry points

#### 3. Test Scripts in `scripts/`
- `miner_workflow.py` - Complete miner workflow
- `assign_proposer.py` - Block proposer assignment
- `start_remote_tunnel.sh` - SSH tunnel management

- Created unified entry point (`aitbc`)
- Set up test structure

### Phase 1: Enhance Existing Tools ✅ (2026-02-11)
- client.py: history, filtering, retry with exponential backoff
- miner.py: earnings, capabilities, deregistration, job filtering, concurrent processing
- wallet.py: multi-wallet, backup/restore, staking, `--wallet-path`
- auth.py: login/logout, token management, multi-environment

### Phase 2: New CLI Tools ✅ (2026-02-11)
- blockchain.py, marketplace.py, admin.py, config.py, simulate.py

### Phase 3: Testing & Documentation ✅ (2026-02-12)
- 116/116 CLI tests passing (0 failures)
- CI/CD workflow (`.github/workflows/cli-tests.yml`)
- CLI reference docs, shell completion, README

### Phase 4: Backend Integration ✅ (2026-02-12)
- MarketplaceOffer model extended with GPU-specific fields
- GPU booking system, review system
- Marketplace sync-offers endpoint

## Success Metrics

1. ✅ **Coverage**: All API endpoints accessible via CLI (client, miner, wallet, auth, blockchain, marketplace, admin, config, simulate)
2. ✅ **Tests**: 116/116 CLI tests passing across all command groups
3. ✅ **Documentation**: Complete command reference with examples (`docs/cli-reference.md` — 560+ lines covering all commands, workflows, troubleshooting, integration)
4. ✅ **Usability**: All common workflows achievable via CLI (job submission, mining, wallet management, staking, marketplace GPU booking, config profiles)
5. ✅ **Performance**: CLI response time < 500ms for local operations (config, wallet, simulate)

## Dependencies

### Core Dependencies
- Python 3.8+
- Click or Typer for CLI framework
- Rich for terminal formatting
- Pytest for testing
- httpx for HTTP client
- PyYAML for configuration

### Additional Dependencies
- **keyring** - Encrypted credential storage
- **cryptography** - Secure credential handling
- **click-completion** - Shell auto-completion
- **tabulate** - Table formatting
- **colorama** - Cross-platform colored output
- **pydantic** - Configuration validation
- **python-dotenv** - Environment variable management

## Risks & Mitigations

1. **API Changes**: Version CLI commands to match API versions
2. **Authentication**: Secure storage of API keys using keyring
3. **Network Issues**: Robust error handling and retries
4. **Complexity**: Keep individual commands simple and composable
5. **Backward Compatibility**: Maintain compatibility with existing scripts
6. **Dependency Conflicts**: Use virtual environments and pin versions
7. **Security**: Regular security audits of dependencies

## Implementation Approach

### Recommended Strategy
1. **Start with `scripts/aitbc-cli.sh`** - It's already a working wrapper
2. **Gradually migrate to Python** - Convert bash wrapper to Python CLI framework
3. **Reuse existing Python scripts** - `miner_workflow.py`, `assign_proposer.py` etc.
4. **Leverage existing `pyproject.toml`** - Just add CLI configuration

### Quick Start Implementation
```bash
# 1. Fix URL inconsistency in existing tools
sed -i 's/127.0.0.1:18000/localhost:8000/g' cli/client.py
sed -i 's/localhost:8001/localhost:8000/g' cli/miner.py

# 2. Create CLI package structure
mkdir -p cli/aitbc_cli/{commands,config,auth}

# 3. Add entry point to pyproject.toml
# [project.scripts]
# aitbc = "aitbc_cli.main:cli"
```

## Marketplace Backend Analysis

### Current Status
The CLI marketplace commands expect GPU-specific endpoints that are **NOW IMPLEMENTED** in the backend:

#### ✅ Implemented GPU Endpoints
- `POST /v1/marketplace/gpu/register` - Register GPU in marketplace ✅
- `GET /v1/marketplace/gpu/list` - List available GPUs ✅
- `GET /v1/marketplace/gpu/{gpu_id}` - Get GPU details ✅
- `POST /v1/marketplace/gpu/{gpu_id}/book` - Book/reserve a GPU ✅
- `POST /v1/marketplace/gpu/{gpu_id}/release` - Release a booked GPU ✅
- `GET /v1/marketplace/gpu/{gpu_id}/reviews` - Get GPU reviews ✅
- `POST /v1/marketplace/gpu/{gpu_id}/reviews` - Add GPU review ✅
- `GET /v1/marketplace/orders` - List orders ✅
- `GET /v1/marketplace/pricing/{model}` - Get model pricing ✅

#### ✅ Currently Implemented
- `GET /marketplace/offers` - Basic offer listing (mock data)
- `GET /marketplace/stats` - Marketplace statistics
- `POST /marketplace/bids` - Submit bids
- `POST /marketplace/sync-offers` - Sync miners to offers (admin)

### Data Model Gaps
1. **GPU Registry**: ✅ Implemented (in-memory storage with mock GPUs)
2. **Booking System**: ✅ Implemented (in-memory booking tracking)
3. **Review Storage**: ✅ Implemented (in-memory review system)
4. **Limited Offer Model**: ✅ Fixed — GPU-specific fields added (`gpu_model`, `gpu_memory_gb`, `gpu_count`, `cuda_version`, `price_per_hour`, `region`)

### Recommended Implementation

#### ✅ Phase 1: Quick Fix (COMPLETED)
```python
# ✅ Created /v1/marketplace/gpu/ router with all endpoints
# ✅ Added mock GPU data with 3 GPUs
# ✅ Implemented in-memory booking tracking
# ✅ Added review system with ratings
```

#### Phase 2: Full Implementation (High Effort)
```python
# New Models Needed:
class GPURegistry(SQLModel, table=True):
    gpu_id: str = Field(primary_key=True)
    miner_id: str
    gpu_model: str
    gpu_memory_gb: int
    status: str  # available, booked, offline
    current_booking_id: Optional[str]
    booking_expires: Optional[datetime]

class GPUBooking(SQLModel, table=True):
    booking_id: str = Field(primary_key=True)
    gpu_id: str
    client_id: str
    duration_hours: float
    total_cost: float
    status: str

class GPUReview(SQLModel, table=True):
    review_id: str = Field(primary_key=True)
    gpu_id: str
    rating: int = Field(ge=1, le=5)
    comment: str
```

### Impact on CLI Tests
- 6 out of 7 marketplace tests fail due to missing endpoints
- Tests expect JSON responses from GPU-specific endpoints
- Current implementation returns different data structure

### Priority Matrix
| Feature | Priority | Effort | Impact |
|---------|----------|--------|--------|
| GPU Registry | High | Medium | High |
| GPU Booking | High | High | High |
| GPU List/Details | High | Low | High |
| Reviews System | Medium | Medium | Medium |
| Order Management | Medium | High | Medium |
| Dynamic Pricing | Low | High | Low |

### Next Steps for Marketplace
1. Create `/v1/marketplace/gpu/` router with mock responses
2. Implement GPURegistry model for individual GPU tracking
3. Add booking system with proper state management
4. Integrate with existing miner registration
5. Add comprehensive testing for new endpoints
