Show HN: Opaal Visual multi-agent prompt designer for Claude Code and agentic AI (github.com)

Opaal has launched a new desktop application designed specifically for creating visual multi-agent workflows for Claude Code and other agentic AI platforms. This innovative tool allows users to construct complex orchestration prompts through a simple drag-and-drop interface, eliminating the need for manual coding. With features like agent role customization, smart auto-connections, live prompt previews, and export options to Claude’s format, Opaal simplifies the process of designing AI pipelines, making it accessible for both seasoned developers and newcomers alike. This open-source project is significant for the AI/ML community as it empowers users to streamline their workflow design, potentially accelerating the development cycles for multi-agent applications. By focusing on the visual composition of agent roles and connections, Opaal enhances understanding of data flow and execution sequences, which could lead to more efficient and effective AI solutions. Moreover, since Opaal operates entirely offline and does not transmit any data, it prioritizes user privacy while fostering a space for creativity and experimentation in AI prompt engineering.
