summary

Positron Assistant is a preview feature you enable in settings and log into Anthropic and GitHub Copilot; it offers ask, edit and agent mode where the agent runs terminal commands, converts multiple scripts into an R package, runs devtools check and iteratively fixes problems with a human approving each step. Databot is an installable extension that loads TidyTuesday measles CSVs, produces ggplot2 charts, a Shiny app and a Quarto report, and writes a databot.md memory file and HTML exports. Ragnar builds DuckDB vector stores with OpenAI embeddings, does smart markdown chunking and UMAP inspection for RAG, and chatlas in Python provides model switching, tool registration and Pydantic-typed structured outputs.
