Running Positron IDE commands: changing the window layout, focusing panes (Console, Variables, Plots, Help, Packages), clearing the console, opening a file or data file in the right editor, discovering interpreters, listing, switching, starting, restarting or interrupting sessions, setting up Python, reading, installing or updating a session's packages, running or debugging a web app (Shiny, Flask, Dash, Streamlit, FastAPI, Gradio, marimo), and reading the Data Connections pane -- connections code cannot see -- including a live connection's tables and columns. Use when the user wants Positron itself to act, or to know what is installed, rather than to run R or Python code. Triggers: "show the variables pane", "open data.csv", "what interpreters are available", "switch to my R session", "my session is stuck", "is pandas installed?", "set up a Python environment", "run my shiny app", "what databases am I connected to", "what tables are in my warehouse", "deploy my app to Connect".
