  description: >-
    A CI failure-response workflow that lists jobs for a GitLab project to find a
    failed pipeline job, opens a GitHub issue to track the build break, and
    notifies a Slack channel so the team can fix the pipeline. Demonstrates
    chaining a CI provider, a source-control provider, and a chat provider in a
    single Arazzo workflow.
