GitHub makes coverage setup a one-click agent task

GitHub put code-coverage setup behind 1 click: a public-preview agent now generates the repository’s workflow and opens a pull request for human review. The generated pipeline builds the code, runs tests, produces a coverage report, and uploads it with least-privilege permissions; access currently covers GitHub Code Quality users on Enterprise Cloud and Team, not Enterprise Server. Operators building the kind of containerized agent regression loop Supabase demonstrated should treat the generated PR as scaffolding, then inspect triggers, permissions, and test commands before merge.
