  title: Azure DevOps Commit a File via a Git Push
  summary: Resolve the tip of a branch, push a new commit, and confirm the push.
  description: >-
    Commits a single file change to an Azure Repos branch through the pushes API.
    The workflow lists the repository refs to resolve the current object ID
    (tip) of the target branch, creates a push whose refUpdate advances that
    branch from the resolved old object ID and whose commit adds or edits a file
    with raw text content, and then lists recent pushes to confirm the new push
    landed. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
