Analyzes your Readwise Reader library and generates a personalized profile that other skills use to tailor their behavior. It spawns a subagent to run parallel queries across your highlights, saved docs, and tags, then writes a structured persona file covering your interests, reading style, current obsessions, and specific triage preferences. Starts with a quick pass in under two minutes, then optionally does a deeper analysis with more targeted queries. The clever bit is the triage guidance section, which teaches downstream skills how to pitch content to you based on your patterns. If you use multiple Reader skills, this makes them much smarter about what you actually care about. Takes some setup time but pays dividends if your library is large and you want personalized filtering.
