This extracts actionable methodologies from documents or examples and turns them into reusable skills. Feed it a tutorial on code reviews or a guide on technical writing, and it'll pull out the steps and criteria. Feed it a polished blog post or proposal, and it'll reverse engineer what made it good and give you a template to create similar work. The two-path approach is smart: it treats "how to" content differently from finished examples. Think of it as the bridge between NotebookLM-style understanding and actually doing the thing repeatedly. Works with PDFs, URLs, YouTube videos, even NotebookLM links. Honestly most useful when you find yourself wanting to replicate a process but the original source is scattered or implicit.
