X Career
The Orange Book series turns product-development and content-creation experience into free Chinese-language learning material. The personal workbench also links the lighting app 小猫补光灯 and other small products. Huashu presents himself as a creator who uses AI to make ideas into working artifacts and then documents the steps for other people.[1][2][6]
Contributions
Turning a named perspective into instructions
Nuwa Skill researches public material about a person and extracts recurring reasoning methods into a reusable agent skill. Its examples apply a named perspective to a new problem rather than simply retrieving quotations. The resulting output remains an AI-generated interpretation of that public material; it is not the person speaking or endorsing the answer. Huashu’s repository packages the research and extraction workflow for compatible coding agents.[3]
A design workflow with visible choices
Huashu Design guides an agent from a brief and optional brand assets to a visual artifact such as a prototype, presentation or animation. It generates candidate directions and uses a style library and checks to develop the selected result. The contribution is the workflow and supporting design context, giving an agent a sequence of decisions to follow instead of relying on one broad request to make something attractive.[4]
Improving a skill through experiments
Darwin Skill adapts an experiment loop to agent instructions. It evaluates an existing skill, proposes a focused change and compares the result before keeping an improvement. Its documented process includes independent reviewers and human checkpoints. Those mechanisms distinguish the proposed improvement from merely rewriting the instructions to sound better. The repository’s own scores describe its chosen evaluations, not a universal measure of agent quality.[5]
