  title: ReadMe Upsert A Guide Page
  summary: Find a guide by slug and update it if it exists, otherwise create it.
  description: >-
    A common documentation-automation pattern: keep a guide page in sync without
    knowing in advance whether it already exists. The workflow lists guides on
    the branch, branches on whether a guide with the target slug is present, and
    then either updates the matched guide or creates a new one. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.

  summary: Update a guide if its slug already exists on the branch, otherwise create it.
  description: >-

    branches to update the existing guide or create a new one.
