llm-coding-agent 0.1a0

The llm-coding-agent 0.1a0 is a new Python library that functions as an autonomous coding assistant. Built upon an existing LLM framework, this tool allows users to perform software development tasks by interacting with a language model that can read files, execute shell commands, and modify code directly.

The agent provides a suite of specific tools for developers, including functions to list and search files, read file contents, and perform precise string replacements. It also supports command execution with built-in timeouts to ensure safety. Users can operate the agent via a command-line interface or through a Python API, which allows for programmatic control over tasks like fixing failing tests or generating new project structures.

This project demonstrates the practical application of agentic workflows in software engineering. By automating repetitive tasks such as file management and command execution, the agent can handle complex requests, such as creating a functional CLI application from a simple prompt. The release is currently available as an alpha version on PyPI, offering a foundation for further experimentation with AI-driven development tools.
