setting COLUMNS env var to a number greater than 0 will make the terminal resize to that number of columns.

[code]
  COLUMNS=80 uvx --from rich-cli rich myscript.py

NOTE
│ Not all programs respct the COLUMNS env var, but rich does, and a lot of stuff I’m building uses rich.

I discovered this when I was trying to make a low effort readme generated from the code, but did not depend on the size of terminal it was ran on.

[code]
  # justfile
  readme:
      echo "# Workspaces" > README.md
      echo "" >> README.md
      echo '``` bash' >> README.md
      COLUMNS=80 ./workspaces.py --help >> README.md
      echo '```' >> README.md
