# CLAIF - Command Line Artificial Intelligence Framework

## 1. Quickstart

CLAIF is a unified Python framework that lets you query multiple AI providers (Claude, Gemini, OpenAI) through one simple interface. Version 1.0.6 enhances the API with more specific error types and improved module exports.

```bash
pip install claif[all] && claif query "Explain quantum computing in one sentence"
```

CLAIF is a unified Python framework for interacting with multiple AI language model providers through a consistent interface. It provides a plugin-based architecture that enables seamless integration with various AI providers while maintaining a common API.

## 2. What is CLAIF?

CLAIF is a lightweight framework that provides:

- **Unified Interface**: Single API to interact with multiple AI providers (Claude, Gemini, Codex/OpenAI)
- **Plugin Architecture**: Dynamic provider discovery through Python entry points
- **Fire CLI**: Command-line interface with rich terminal output
- **MCP Server**: FastMCP server for tool integration
- **Async Support**: Full async/await support for all operations
- **Type Safety**: Comprehensive type hints throughout the codebase

## 3. Installation

### 3.1. Basic Installation

```bash
pip install claif
```

### 3.2. With Provider Packages

CLAIF requires provider packages to be installed separately:

```bash
# Install with all providers
pip install claif[all]

# Or install specific providers
pip install claif claif_cla  # For Claude support
pip install claif claif_gem  # For Gemini support  
pip install claif claif_cod  # For Codex/OpenAI support
```

### 3.3. Development Installation

```bash
git clone https://github.com/twardoch/claif.git
cd claif
pip install -e ".[dev,test]"
```

## 4. CLI Usage

CLAIF provides a comprehensive command-line interface built with Fire.

### 4.1. Basic Commands

```bash
# Query default provider
claif query "What is Python?"

# Query specific provider
claif query "Explain recursion" --provider claude

# Query with options
claif query "Write a haiku" --temperature 0.7 --max-tokens 50

# Stream responses in real-time
claif stream "Tell me a story" --provider gemini

# Query random provider
claif random "Tell me a joke"

# Query all providers in parallel
claif parallel "What is AI?" --compare
```

### 4.2. Provider Management

```bash
# List available providers and their status
claif providers list

# Check provider health
claif providers status
```

### 4.3. Configuration

```bash
# Show current configuration
claif config show

# Set default provider
claif config set default_provider=gemini

# Save configuration
claif config save
```

### 4.4. MCP Server

```bash
# Start the MCP (Model Context Protocol) server
claif server --host localhost --port 8000
```

## 5. Python API Usage

### 5.1. Basic Usage

```python
import asyncio
from claif import ClaifOptions, Provider
from claif.client import query

async def main():
    # Query default provider
    async for message in query("Hello, world!"):
        print(message.content)
    
    # Query specific provider  
    options = ClaifOptions(provider=Provider.CLAUDE)
    async for message in query("Explain Python", options):
        print(message.content)

asyncio.run(main())
```

### 5.2. Advanced Options

```python
from claif import ClaifOptions, Provider

options = ClaifOptions(
    provider=Provider.GEMINI,
    model="gemini-pro",
    temperature=0.7,
    max_tokens=1000,
    system_prompt="You are a helpful assistant",
    timeout=30,
    cache=True,
    verbose=True
)

async for message in query("Complex question", options):
    print(message.content)
```

### 5.3. Parallel Queries

```python
from claif.client import query_all, query_random

# Query all providers in parallel
async for results in query_all("What is machine learning?"):
    for provider, messages in results.items():
        print(f"\n{provider.value}:")
        for msg in messages:
            print(msg.content)

# Query random provider
async for message in query_random("Tell me a joke"):
    print(message.content)
```

### 5.4. Using the Client Class

```python
from claif.client import ClaifClient
from claif import ClaifOptions, Provider

client = ClaifClient()

# List available providers
providers = client.list_providers()
print(providers)  # [Provider.CLAUDE, Provider.GEMINI, Provider.CODEX]

# Query specific provider
options = ClaifOptions(provider=Provider.CLAUDE)
async for message in client.query("Hello", options):
    print(message.content)
```

## 7. How It Works

### 7.1. Architecture Overview

CLAIF uses a layered architecture:

```
┌─────────────────────────────┐
│      User Application       │
├─────────────────────────────┤
│        CLAIF CLI           │ ← Fire-based CLI with rich output
├─────────────────────────────┤
│      CLAIF Client          │ ← Async client with provider routing
├─────────────────────────────┤
│    Common Types/Utils      │ ← Shared data structures and utilities
├─────────────────────────────┤
│    Provider Wrappers       │ ← Simple adapters for provider packages
├─────┬─────┬─────┬──────────┤
│claif_cla│claif_gem│claif_cod│ ← Actual provider implementations
└─────┴─────┴─────┴──────────┘
```

### 7.2. Core Components

#### 7.2.1. **Common Module** (`src/claif/common/`)

Provides shared functionality across all providers:

- **types.py**: Core data structures
  - `Message`: Base message class with role and content
  - `Provider`: Enum of supported providers (CLAUDE, GEMINI, CODEX)
  - `ClaifOptions`: Configuration for queries
  - `TextBlock`, `ToolUseBlock`, `ToolResultBlock`: Content block types
  - `ResponseMetrics`: Performance tracking

- **config.py**: Configuration management
  - Hierarchical loading: defaults → files → environment → CLI
  - Provider-specific configurations
  - Session and cache settings

- **errors.py**: Exception hierarchy
  - `ClaifError`: Base exception
  - `ProviderError`: Provider-specific errors
  - `ConfigurationError`: Config issues

- **utils.py**: Utilities
  - Response formatting (text, JSON, markdown)
  - Progress indicators
  - Logging configuration

#### 7.2.2. **Providers Module** (`src/claif/providers/`)

Simple wrapper classes that delegate to provider packages:

```python
# claude.py
class ClaudeProvider:
    async def query(self, prompt: str, options: ClaifOptions) -> AsyncIterator[Message]:
        async for message in claude_query(prompt, options):
            yield message
```

Each provider wrapper:
- Imports the actual provider package (`claif_cla`, `claif_gem`, `claif_cod`)
- Implements the same `query` interface
- Logs debug information

#### 7.2.3. **Client Module** (`src/claif/client.py`)

The main client implementation:

```python
class ClaifClient:
    def __init__(self):
        self.providers = {
            Provider.CLAUDE: ClaudeProvider(),
            Provider.GEMINI: GeminiProvider(),
            Provider.CODEX: CodexProvider(),
        }
```

Features:
- Routes queries to appropriate providers
- Implements `query`, `query_random`, and `query_all`
- Handles provider selection and error recovery

#### 7.2.4. **CLI Module** (`src/claif/cli.py`)

Fire-based CLI with rich terminal output:

```python
class ClaifCLI:
    def __init__(self, config_file=None, verbose=False):
        # Configure loguru based on verbose flag
        logger.remove()
        log_level = "DEBUG" if verbose else "INFO"
        logger.add(sys.stderr, level=log_level)
```

Commands:
- `query`: Basic queries with options
- `stream`: Live streaming responses
- `random`: Query random provider
- `parallel`: Query all providers
- `providers`: List and check health
- `config`: Manage configuration
- `server`: Start MCP server

#### 7.2.5. **Server Module** (`src/claif/server.py`)

FastMCP server implementation providing tools:
- `claif_query`: Query specific provider
- `claif_query_random`: Query random provider
- `claif_query_all`: Query all providers
- `claif_list_providers`: List available providers
- `claif_health_check`: Check provider health

### 7.3. Configuration System

Configuration is loaded hierarchically:

1. **Default values** in `Config` dataclass
2. **Config files**:
   - `~/.claif/config.json`
   - `~/.config/claif/config.json`
   - `./claif.json`
3. **Environment variables**: `CLAIF_*`
4. **CLI arguments**

Example configuration:

```json
{
    "default_provider": "claude",
    "providers": {
        "claude": {
            "enabled": true,
            "model": "claude-3-opus-20240229",
            "api_key_env": "ANTHROPIC_API_KEY"
        },
        "gemini": {
            "enabled": true,
            "api_key_env": "GEMINI_API_KEY"
        }
    },
    "cache_enabled": true,
    "cache_ttl": 3600
}
```

### 7.4. Plugin System

CLAIF uses Python's entry points for dynamic provider discovery:

```python
# In src/__init__.py
class PluginFinder:
    """Enables imports like: from claif import claude"""
    def find_spec(cls, fullname, path, target=None):
        # Looks up plugins via entry points
```

Provider packages register themselves:

```toml
# In provider's pyproject.toml
[project.entry-points."claif.plugins"]
claude = "claif_cla"
```

### 7.5. Message Flow

1. **User Input**: CLI command or API call
2. **Options Parsing**: Create `ClaifOptions` with configuration
3. **Provider Selection**: Choose provider based on options
4. **Query Routing**: Client routes to appropriate provider wrapper
5. **Provider Execution**: Provider package handles actual API call
6. **Response Streaming**: Yield `Message` objects as they arrive
7. **Output Formatting**: Display with rich or return structured data

### 7.6. Logging System

CLAIF uses loguru for simple, powerful logging:

- Automatic configuration based on verbose flag
- Debug logs for provider selection and queries
- Info logs for configuration changes
- Warning logs for missing features
- Structured logging with context
