llm-coder 0.0.1

llm による自立型 Cli コーディングエージェントライブラリ

llm-coder

日本語

llm-coder is an autonomous CLI coding agent library powered by LLMs.

It codes according to user instructions, runs its own linter, formatter, and test code in an evaluation phase, and keeps fixing until all checks pass. The LLM API interface uses the litellm library, allowing you to use any LLM such as Claude or OpenAI. Model and API key configuration follows the litellm provider settings.
See https://docs.litellm.ai/docs/providers for details.

Installation

1. Clone the repository:

   git clone https://github.com/igtm/llm-coder.git
   cd llm-coder
   

2. Install the package in development mode:

   pip install -e .
   

   This makes the llm-coder command available in your project directory.

Usage

After installation, you can run the CLI tool with:

llm-coder <prompt> [options...]

Available Options

positional arguments:
  prompt                Prompt to execute (if omitted, read from stdin or TOML file)

options:
  -h, --help            Show help message and exit
  --config CONFIG       Path to TOML config file (default: llm-coder-config.toml)
  --model MODEL, -m MODEL
                        LLM model to use (default: gpt-4.1-nano)
  --temperature TEMPERATURE, -t TEMPERATURE
                        LLM temperature parameter (default: 0.5)
  --max-iterations MAX_ITERATIONS, -i MAX_ITERATIONS
                        Maximum execution iterations (default: 10)
  --allowed-dirs ALLOWED_DIRS [ALLOWED_DIRS ...]
                        Directories allowed for file system operations (space separated, default: ['.', 'playground'])
  --repository-description-prompt REPOSITORY_DESCRIPTION_PROMPT
                        Repository description prompt for LLM (default: from TOML file or empty)
  --output OUTPUT, -o OUTPUT
                        Output file path (default: none, stdout only)
  --conversation-history CONVERSATION_HISTORY, -ch CONVERSATION_HISTORY
                        Output file path for agent conversation history (default: none)
  --request-timeout REQUEST_TIMEOUT
                        Timeout per LLM API request in seconds (default: 60)

Examples

# Basic usage
llm-coder "Create a python script that outputs 'hello world'"

# Specify model
llm-coder --model claude-3-opus-20240229 "Create a python script that outputs 'hello world'"

# Specify temperature and max iterations
llm-coder --temperature 0.7 --max-iterations 5 "Create a python script that outputs 'hello world'"

# Specify allowed directories
llm-coder --allowed-dirs . ./output ./src "Create a python script that outputs 'hello world'"

# Specify request timeout
llm-coder --request-timeout 120 "Create a python script that outputs 'hello world'"

# Output result to file
llm-coder --output result.txt "Create a python script that outputs 'hello world'"

# Output conversation history to file
llm-coder --conversation-history conversation.txt "Create a python script that outputs 'hello world'"

# Output both result and conversation history to files
llm-coder --output result.txt --conversation-history conversation.txt "Create a python script that outputs 'hello world'"

Configuration

You can configure llm-coder via command line arguments or a TOML file.

Priority: Command line arguments > TOML config file > hardcoded defaults

Example TOML Config File

By default, llm-coder-config.toml is loaded. You can specify a custom config file with --config.

# Global settings
model = "claude-3-opus-20240229"
prompt = "Create a python script that outputs 'hello world'"
temperature = 0.5
max_iterations = 10
request_timeout = 60
allowed_dirs = ["."]
repository_description_prompt = "This repository is a Python utility tool."
# output = "result.txt"
# conversation_history = "conversation.txt"

To use a config file:

# Use default config file (llm-coder-config.toml)
llm-coder

# Specify custom config file
llm-coder --config my_config.toml

Running Directly During Development

You can run cli.py directly during development without installing. A playground directory is provided for testing, but you must run scripts from the project root directory.

From the project root (llm-coder top directory), run:

# Make sure you are in the project root directory
uv run python -m llm-coder.cli <args...>

Example:

# Assuming you are in the project root directory
uv run python -m llm-coder.cli "Create a python script that outputs 'hello world'"

llm-coder-litellm Command

The llm-coder-litellm command is a simple wrapper for calling the LLM completion API directly using the LiteLLM library.

llm-coder-litellm --model <model> [options...] "prompt"

Available Options

usage: llm-coder-litellm [-h] --model MODEL [--temperature TEMPERATURE] [--max_tokens MAX_TOKENS] [--top_p TOP_P] [--n N] [--stream] [--stop [STOP ...]]
                         [--presence_penalty PRESENCE_PENALTY] [--frequency_penalty FREQUENCY_PENALTY] [--user USER] [--response_format RESPONSE_FORMAT]
                         [--seed SEED] [--timeout TIMEOUT] [--output OUTPUT] [--extra EXTRA]
                         [prompt]
