Repo-local automation for App Store Connect that feels like Fastlane lanes but outputs machine-readable JSON. You define multi-step workflows in `.asc/workflow.json`, validate them, dry-run them, then execute with runtime parameters. Steps can declare outputs extracted via JSONPath, reference each other with `${steps.name.OUTPUT}`, and use conditionals. The resume flag lets you restart failed runs from their saved state. Honestly most useful for release and TestFlight workflows where you need auditable, repeatable sequences that string together `asc` commands with proper output chaining. The examples show real patterns like resolving the latest build ID then conditionally adding it to a beta group based on whether you passed `GROUP_ID`.
