LMSYS SDK

A Python SDK for interacting with the Claude CLI tool.

Installation

pip install lmsys

Requirements

• Python 3.8+
• Claude CLI tool must be installed and available in your PATH

Quick Start

from lmsys import Agent

# Initialize with a working directory
agent = Agent(working_dir="/path/to/your/project")

# Run Claude with a prompt
result = agent.run("Your prompt here")
print(result)

# Auto-streaming output (prints automatically)
lines = agent.run("Generate a story", stream=True)

# Manual streaming (if you need more control)
process = agent.run("Another prompt", stream=True, auto_print=False)
for line in process.stdout:
    print(line, end="")

Features

• Simple interface to the Claude CLI tool
• Support for all Claude CLI options
• Automatic or manual streaming output
• Customizable tool access

API Reference

Agent Class

Agent(working_dir=None, allowed_tools=None)

Parameters:

• working_dir (str, optional): The working directory for Claude to use. Defaults to current directory.
• allowed_tools (list, optional): List of tools to allow Claude to use. Defaults to ["Edit", "Bash", "Write"].

Methods

run

run(prompt, stream=False, output_format=None, additional_args=None, auto_print=True)

Run Claude with the specified prompt.

Parameters:

• prompt (str): The prompt to send to Claude.
• stream (bool): If True, handles streaming output. If False, returns the complete output.
• output_format (str, optional): Optional output format (e.g., "stream-json").
• additional_args (dict, optional): Additional arguments to pass to the Claude CLI.
• auto_print (bool): If True and stream=True, automatically prints output. If False, you need to handle streaming manually.

Returns:

• If stream=False: Returns the complete output as a string.
• If stream=True and auto_print=False: Returns a subprocess.Popen object for manual streaming.
• If stream=True and auto_print=True: Automatically prints output and returns collected lines as a list.

run_with_tools

run_with_tools(prompt, tools, stream=False, auto_print=True)

Run Claude with specific allowed tools.

Parameters:

• prompt (str): The prompt to send to Claude.
• tools (list): List of tools to allow Claude to use.
• stream (bool): If True, handles streaming output.
• auto_print (bool): If True and stream=True, automatically prints output.

Returns:

• If stream=False: Returns the complete output as a string.
• If stream=True and auto_print=False: Returns a subprocess.Popen object.
• If stream=True and auto_print=True: Automatically prints output and returns collected lines.

Example: Automatic Streaming

from lmsys import Agent

agent = Agent()
# This will automatically print the output line by line
lines = agent.run("Generate a short story", stream=True)

Example: Manual Streaming with JSON parsing

from lmsys import Agent
import json

agent = Agent()
process = agent.run("Generate a short story", stream=True, output_format="stream-json", auto_print=False)

for line in process.stdout:
    if line.strip():
        try:
            data = json.loads(line)
            print(data.get("content", ""))
        except json.JSONDecodeError:
            print(f"Error parsing JSON: {line}")
