rookie-ricardo/erduo-skills ? reverse-engineered prompt

Build me a small open source skills library for AI agents, with a clean README and a few ready to use workflows. I want it to let an agent fetch and summarize tech news, turn RSS feeds into a filtered digest, polish messy transcript text into readable articles, translate articles with a careful multi step process, turn web pages into clean Markdown, make polished diagram images, and include a simple tool for removing Gemini watermarks from images.

Make it easy to install with a single command, and also support Claude Code plugin style installation. Each skill should live in its own folder with clear instructions and any scripts it needs. Include example prompts for each one, plus enough docs so someone can understand what each skill does and how to use it without reading the code first. If you need to, look up the current docs online for the agent tools involved.
