Hi, I’m Rainman (@deusyu).

I build open-source tools and field notes for AI-native software engineering: harness engineering, context engineering, agent workflows, and Claude Code / Codex skills.

My current public work includes Harness Engineering, translate-book, claude-resume, and a growing set of Agent Skills for making AI coding agents more reliable in real projects.

Sponsorship helps keep this work public, documented, and maintained. It covers the time and model/API credits needed to turn private experiments into reusable open-source artifacts: docs, examples, tests, templates, and practical guides.

This is not a paid support contract or consulting channel. Sponsors support the continuation of public work.

3 sponsors have funded deusyu’s work.

@deusyu

covers the model & API credits I burn building and testing these Agent Skills, so they stay maintained and free for everyone.
