claif_gem 1.0.8

Google Gemini provider for Claif (Command-Line AI Framework)

#claif_gem - Google Gemini Provider for Claif

Quickstart

Claif_GEM provides a Python interface and CLI wrapper for Google's Gemini AI models. It integrates the Gemini CLI tool into the Claif framework, enabling you to query Gemini models with a simple command or Python API call. Version 1.0.4 improves subprocess reliability by switching to native asyncio.

pip install claif_gem && claif-gem query "Explain quantum computing in one sentence"

Claif_GEM is the Google Gemini provider implementation for the Claif (Command-Line Artificial Intelligence Framework). It wraps the Gemini CLI to integrate Google's Gemini AI models into the unified Claif ecosystem.

What isclaif_gem?

Claif_GEM provides a Python interface and command-line wrapper for the Google Gemini CLI tool. It enables seamless integration of Google's Gemini language models with the Claif framework through subprocess management and message translation.

Key features:

• Subprocess-based integration with the Gemini CLI binary
• Automatic CLI discovery across multiple platforms (Windows, macOS, Linux)
• Fire-based CLI with rich terminal output for direct usage
• Async/await support for efficient concurrent operations
• Auto-approval and yes-mode for streamlined workflows
• Flexible configuration via environment variables and options
• Robust error handling with timeout protection

Installation

Prerequisites

You need to have the Gemini CLI installed. Install it via npm:

npm install -g @google/gemini-cli

Or set the path to an existing installation:

export GEMINI_CLI_PATH=/path/to/gemini

From PyPI

pip install claif_gem

From Source

git clone https://github.com/twardoch/claif_gem.git
cd claif_gem
pip install -e .

With Claif Framework

# Install Claif with all providers
pip install claif[all]

# Or just with Gemini support
pip install claif claif_gem

CLI Usage

Claif_GEM provides a Fire-based CLI for direct interaction with Gemini:

Basic Commands

# Simple query
claif-gem query "Explain quantum computing"

# Query with specific model
claif-gem query "Write a haiku" --model gemini-2.5-pro

# Query with parameters
claif-gem query "Analyze this code" --temperature 0.3 --max-context 8000

# With system prompt
claif-gem query "Translate to Spanish" --system "You are a professional translator"

# Stream responses
claif-gem stream "Tell me a story"

# Health check
claif-gem health

# List available models
claif-gem models

# Show configuration
claif-gem config show

Options

• --model: Specify Gemini model (default: gemini-2.5-pro)
• --temperature: Control randomness (0-1)
• --system: Set system prompt for context
• --auto-approve: Auto-approve tool usage (default: true)
• --yes-mode: Automatically confirm all prompts (default: true)
• --max-context: Maximum context length
• --timeout: Query timeout in seconds
• --show-metrics: Display response metrics
• --verbose: Enable debug output

Python API Usage

Basic Usage

import asyncio
from claif_gem import query, GeminiOptions

async def main():
    # Simple query
    async for message in query("Hello, Gemini!"):
        print(message.content)
    
    # Query with options
    options = GeminiOptions(
        model="gemini-2.5-pro",
        temperature=0.7,
        system_prompt="You are a helpful coding assistant",
        auto_approve=True,
        yes_mode=True
    )
    
    async for message in query("Explain Python decorators", options):
        print(message.content)

asyncio.run(main())

Direct Client Usage

from claif_gem.client import GeminiClient
from claif_gem.types import GeminiOptions

async def main():
    client = GeminiClient()
    options = GeminiOptions(
        model="gemini-2.5-pro",
        verbose=True
    )
    
    async for message in client.query("What is machine learning?", options):
        print(f"[{message.role}]: {message.content}")

asyncio.run(main())

Transport Layer Access

from claif_gem.transport import GeminiTransport
from claif_gem.types import GeminiOptions

async def main():
    transport = GeminiTransport()
    options = GeminiOptions(timeout=60)
    
    async for response in transport.send_query("Complex analysis", options):
        if hasattr(response, 'content'):
            print(response.content)

asyncio.run(main())

Component Details

1. Main Module (__init__.py)

• Provides the query() function as the main entry point
• Converts Claif's ClaifOptions to GeminiOptions
• Delegates to the client module for execution
• Exports public API: query and GeminiOptions

2. CLI Module (cli.py)

• Fire-based command-line interface
• Commands: query, stream, health, models, config
• Rich console output with progress indicators
• Async execution with proper error handling
• Response formatting and metrics display

3. Client Module (client.py)

• GeminiClient class manages the query lifecycle
• Coordinates with transport layer
• Converts Gemini messages to Claif message format
• Module-level _client instance for convenience

4. Transport Module (transport.py)

• GeminiTransport handles subprocess communication
• CLI discovery across platforms (npm paths, common locations)
• Command-line argument construction from options
• Async subprocess execution with anyio
• Output parsing (JSON and plain text)
• Error handling and timeout management

5. Types Module (types.py)

• GeminiOptions: Configuration dataclass
• GeminiMessage: Response message type
• ResultMessage: Metadata and error information
• Type conversion methods to Claif formats

Message Flow

1. Query Entry: User calls query() with prompt and options
2. Option Translation:Claif options → GeminiOptions
3. Client Processing: GeminiClient validates and prepares query
4. Transport Execution:
   • Find Gemini CLI binary
   • Build command with arguments
   • Spawn subprocess with anyio
   • Read stdout/stderr streams
5. Response Parsing:
   • Try JSON parsing first
   • Fallback to plain text
   • Convert to GeminiMessage
6. Message Conversion: GeminiMessage →Claif Message
7. Async Yield: Messages yielded to caller

CLI Discovery

The transport layer searches for the Gemini CLI in this order:

1. GEMINI_CLI_PATH environment variable
2. System PATH (which gemini)
3. Common installation paths:
   • ~/.local/bin/gemini
   • /usr/local/bin/gemini
   • /opt/gemini/bin/gemini
4. NPM global paths:
   • Windows: %APPDATA%/npm/gemini.cmd
   • Unix: ~/.npm-global/bin/gemini
   • System: /usr/local/lib/node_modules/.bin/gemini

Command Construction

The Gemini CLI is invoked with arguments based on options:

gemini \
  -m <model> \
  -a  # auto-approve
  -y  # yes-mode
  -t <temperature> \
  -s <system-prompt> \
  --max-context <length> \
  -p "prompt"

Environment Variables

• GEMINI_CLI_PATH: Path to Gemini CLI binary
• GEMINI_SDK=1: Set by transport to indicate SDK usage
• Claif_PROVIDER=gemini: Provider identification

Why Useclaif_gem?

1. Unified Interface: Access Gemini through the standard Claif API
2. Cross-Platform: Automatic CLI discovery works on Windows, macOS, Linux
3. Async First: Built on anyio for efficient concurrent operations
4. Rich CLI: Fire-based interface with progress indicators and formatting
5. Type Safety: Full type hints for better IDE support
6. Error Handling: Robust subprocess management with timeout protection
7. Flexible Configuration: Environment variables, options, and config files
