  summary: Open a GitHub pull request, then notify Slack and Microsoft Teams.
  description: >-
    A CI collaboration workflow that opens a pull request in a GitHub
    repository, notifies a Slack channel for code review, and posts the same
    announcement to a Microsoft Teams channel so reviewers across both tools are
    aware. Demonstrates chaining a source-control provider, a chat provider, and
    a collaboration provider in a single Arazzo workflow.
