# Central Claude dispatcher: trigger via API or UI with a target repo + a free-text task.
|
||||
# Claude has the gh CLI authenticated, so a prompt can just reference an issue/PR URL and
|
||||
# Claude pulls it for context; it implements the change on a new branch and the workflow
|
||||
# opens a PR on the target repo.
