Show HN: Patchwork – Open-source framework to automate development gruntwork

Patchwork is a tool designed to automate development tasks such as pull request reviews, bug fixing, and security patching through a self-hosted CLI agent and large language models (LLMs). Key features include reusable actions for tasks like creating pull requests, customizable prompt templates for library updates and code generation, and LLM-assisted automations called Patchflows that streamline processes like PR reviews and documentation. Installation can be done via pip with the command `pip install 'patchwork-cli[all]' --upgrade`. Users can execute Patchflows using the command `patchwork <PatchFlow> <?Arguments>`, with examples including running an AutoFix patchflow by providing OpenAI and GitHub API keys. Available Patchflows include GenerateDocstring for creating method docstrings, AutoFix for addressing code vulnerabilities, PRReview for summarizing changes in pull requests, GenerateREADME for documentation, DependencyUpgrade for updating dependencies, and ResolveIssue for identifying and fixing code issues. Contributions to the project are encouraged, with guidelines for creating new patchflows and steps provided. Patchwork is licensed under AGPL-3.0, while custom patchflows can be shared under Apache-2.0. Additional information can be found in the documentation and a demo video.
