The paper introduces Open Code, a lightweight, terminal-based, open-source agent designed for code development, and then presents Oh My Open Code, a plugin that significantly enhances Open Code's capabilities by integrating a sophisticated multi-agent system.

Open Code: The Base Agent
Open Code is described as a versatile tool for coders, offering a user-friendly interface either through the command line or a web-based UI. Installation is straightforward, typically via npm (npm install -g open-code). Once installed, users can initiate development by typing their desired project (e.g., "create a To-Do list web app, modern design"). The system supports a sequential workflow: pressing Tab once initiates the plan phase, outlining the development steps, and pressing Tab again triggers the build phase, where the code is generated. Open Code allows for flexible model selection (e.g., s/model command to switch between various LLMs like bigfcl). For enhanced usability, it can be accessed through a web UI by pressing Ctrl+P and selecting "Open Web UI," providing a more intuitive graphical interface similar to perplexity for model selection and interaction. While capable of generating functional code for simple tasks (demonstrated by a basic To-Do list app with index.html and minimal CSS), the paper notes its limitation in handling more complex web development scenarios with richer architectural requirements.

Oh My Open Code: Multi-Agent Collaboration and Ultra Work Mode
To address the limitations of standalone Open Code, the paper introduces Oh My Open Code, a plugin developed in Korea. This plugin transforms Open Code into a powerful multi-agent system, drawing an analogy to the myth of Sisyphus: just as Sisyphus struggled to roll a stone, traditional LLM agents might struggle with complex development tasks. Oh My Open Code aims to make this process more efficient by distributing tasks among specialized agents.

Core Methodology: Role-Based Agent Specialization and Parallel Execution
Oh My Open Code's core methodology revolves around a hierarchical and specialized team of LLM agents, each assigned a specific role based on its inherent strengths. This architecture facilitates more robust and efficient code generation for complex projects.

1. Sisyphus: Acts as the main team leader or manager. Its primary role is to oversee the entire development process, ensuring coordination among the subordinate agents and guiding the overall "stone rolling" (code development) effort more effectively.
2. Oracle (e.g., GPT-4.0/5.0 based): Specializes in logical design, inference, and debugging. Models with strong reasoning capabilities are assigned this role to handle the architectural planning and problem-solving aspects of development.
3. Gemini 1.5 (or similar creative models): Responsible for creative UI/UX coding. Models adept at generating innovative and aesthetically pleasing user interfaces are utilized here.
4. Claude Sonnet (or similar document-oriented models): Serves as a librarian or explorer agent, primarily handling documentation lookup and information retrieval. This ensures that agents have access to relevant information and best practices.
5. Explorer, Librarian, Frontend/UI/UX Engineer: These are additional specialized agents that may be activated depending on the task, contributing to specific aspects of discovery, resource management, and interface development.

Ultra Work Mode (ULW): A key feature of Oh My Open Code, ULW leverages these parallel agents for optimized performance. When a complex task is requested with the ULW flag (e.g., ULW ULW in the prompt), Oh My Open Code activates this mode. This triggers a context where tasks are divided and executed concurrently by multiple agents. For example, in the To-Do list demonstration, enabling ULW mode led to the activation of three specific agents: "Explorer," "Librarian," and "Frontend UI/UX Engineer." These agents collaboratively work on different aspects of the project, leading to a more sophisticated and structurally complex output compared to a project generated without the multi-agent system. The resulting To-Do list application created with Oh My Open Code exhibited advanced features like active/completed task states, demonstrating the effectiveness of agent collaboration.

Installation of Oh My Open Code involves running npx @ohmyopen/open-code install. Once installed, Open Code recognizes the plugin, and commands like s/sisyphus become available, indicating the activation of the multi-agent framework. This integration allows users to leverage the power of specialized, collaborative agents directly within the familiar Open Code environment, leading to enhanced development capabilities for intricate projects.
