Acorn

Acorn is an autonomous coding agent designed to operate within the terminal, assisting developers by reading code, writing files, running commands, and performing refactoring tasks across entire codebases. It leverages real-time streaming, allowing users to see tokens generated character-by-character, and incorporates smart model routing to optimize for task complexity and cost. The tool is powered by Gemini, with support for Vertex AI for enterprise use.

Key features of Acorn include project-aware context, enabling it to understand and adapt to the specific structure and conventions of a codebase. toml configuration file. Acorn offers precise file editing by modifying specific lines rather than entire files, and supports multi-file refactoring, allowing edits across multiple files in a single session. Additional capabilities include image analysis for attached screenshots, undo support to instantly revert the last file change, and session persistence to resume conversations where they left off. The agent also features intelligent error handling with auto-retry recovery, a three-tier permission system (safe/ask/deny) for secure operations, and cost tracking to monitor session spending in real-time. Its git-aware functionality enables understanding of branch, status, and project structure.

Installation is straightforward via PyPI, requiring only a Gemini API key to get started. Acorn can also guide users through setup if no API key is provided at launch. The tool is licensed under the MIT License and was created by Andama Godwin. Acorn is aimed at developers seeking to enhance productivity in coding, refactoring, and debugging tasks directly from the terminal, with features tailored for both individual and enterprise environments.
