# Assign Contributor Issue — auto-assign labeled contributor issues
#
# When an issue has both a `.contrib/good *` label and an `area:` label,
# finds the least-busy contributor interested in that area (via Tally form
# responses), assigns the issue, updates the project board, and notifies
# the contributor on Slack.
#
# Errors and "no candidates" conditions are reported to the Slack activity
# channel.
