it's failing

Run is_dependabot=$(echo EshaanAgg | grep -o 'dependabot')
  is_dependabot=$(echo EshaanAgg | grep -o 'dependabot')
  echo "is_dependabot=$is_dependabot" >> $GITHUB_OUTPUT
  shell: /usr/bin/bash -e {0}

could it be that grep exits with error code?

[yurishkuro]

yep

$ echo foo | grep bar

@yurishkuro Sorry for so many extraneous commits! This is the indented functionality right?

[yurishkuro]

This is much cleaner! Thanks.
