Paper Research
Use when user wants to run the full academic paper research pipeline from finding papers through to structured Obsidian output. Use when user says "research papers on X", "help me collect literature on Y", "batch process these papers", or "set up my paper workflow".
Paper Fetch

Paper Wiki

Produces deep, chapter-by-chapter paper breakdowns and detailed concept entries — not summaries. Use when user says "add to my wiki", "build wiki entries", "deep dive on this paper", "explain this paper Karpathy style", or when paper-research calls this sub-skill.
Paper Version
