Get ready creative writers! Inkwell is proud to announce Reading Club, our latest event for the Shanghai writing community. Reading Club is a low stress literature gathering that meets every other Monday evening. We read through through a short short or essay at the meeting and then discuss it. Add Ryan (WechatID: texaswriter) to join our wechat and find out what text is being discussed next. I don't keep Meetup very up to date and everything Inkwell does is organized through its wechat groups, so even if the number of attendees on meetup is low, there's likely an event still going on. Add Ryan, and you can join the wechat group where everything is happening. Some Frequently Asked Questions: What do we do here?: Read classic short stories, short plays, and essays and discuss them. We read them at the meeting, so no advanced reading is required. For second language readers, we distribute the reading in advance to give you extra time. What to bring?: Something to read the text. Phone or tablet words great. What we don't do?: Read giant books in advance. What does it cost?: Free, but please order a drink or snack to support Garden Books.

We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
