# Usage: with fzf use `tab ->` select workflow, sue arrow keys, up/down to move between entries

# Delete workflow runs - dwr

# Given an "owner/repo" name, such as "qmacro/thinking-aloud",
# retrieve the workflow runs for that repo and present them in a
# list. Selected runs will be deleted. Uses the GitHub API.

# Requires gh (GitHub CLI) and jq (JSON processor)

# First version
