fabric, in the simplest sense, is a CLI tool for a curated repository of prompts. It being a CLI tool means you can pipe stdin to it, so you can pass any file to it as input. It also offers some other niceties like a youTube transcription tool so you can use the prompts on youtube videos/podcasts/etc...

fabric has been out for a while but it wasn't very useful without a premium model like chatGPT. Now that deepseek-r1 was unleashed as an open source model, you can use this tool to improve your workflow in a variety of ways.

I've been playing with it using the summarize pattern mostly to read through MSM news articles (for example, some of yogthos posts), it works great and produces a clean markdown file as an output.
