Build an Excel literature table on a topic. Searches economics journals and working papers (via OpenAlex) and compiles a formatted .xlsx with columns: authors, year, title, journal, full citation (AEA), keywords, abstract, citation count, paper type, OA status, link - plus any custom columns the user asks for in that run. Optionally downloads the papers' PDFs to a folder (open-access/working-paper version, else marks "not available"). Use when the user asks to make a literature table or spreadsheet of papers, do a lit search into Excel, build a bibliography table, or collect/download papers on a topic. Complements (does not replace) lit-review-assistant, which is for synthesis prose.
Interactive step-by-step code walkthrough for entire codebases (single or multi-file). Explains each section's logic, assumptions, and data transformations, then RUNS the code and shows actual output - dataframe dimensions, head(), model summaries, plot descriptions, file previews. Pauses after each section for questions. Use whenever the user says "walk through", "explain", "go through", "break down", "review", "understand", "what does this code do", "help me understand this script", "annotate", "explain step by step", or "walk me through the codebase". Also trigger if someone just points at a file/folder and says "explain this". Primarily R but works with any language.
