ErlichLiu

ErlichLiu is a software publisher focused on AI agent tooling, distributing its work through the Proma project at proma.cool. The publisher's catalog currently centers on a single flagship product, Proma, an open-source implementation built on the Claude Agent SDK that aims to deliver a smooth, general-purpose agent experience within professional workflows. Proma is positioned as a forward-looking product for highly skilled "100x" professional users, with its development roadmap oriented toward the proactive agent stage, where software acts on behalf of users rather than merely responding to commands. The project natively supports invocation through Feishu (Lark) group chats, making it suitable for teams that want to embed agent capabilities directly into their everyday collaboration channels, and it offers flexible integration with arbitrary large language model providers, allowing organizations to choose or switch model backends according to their cost, compliance, or performance requirements. Typical use cases for this category of software include automating repetitive knowledge work, orchestrating multi-step tasks through conversational interfaces, extending chat platforms with intelligent assistants, and giving technical teams a customizable foundation for building internal agent-driven tools. Because Proma is released as a complete open-source practice built on an established agent SDK, it also serves as a reference implementation for developers who want to study, adapt, or extend production-grade agent architectures. Overall, ErlichLiu's product range reflects a focused commitment to the emerging field of autonomous and proactive AI agents, targeting professional users and teams who want top-tier agent capabilities running inside their daily workflows rather than confined to standalone applications.
