What problem does it solve? Managing multi-step App Store Connect release tasks manually is error-prone and repetitive. This Skill lets you define trusted, version-controlled automation workflows in .asc/workflow.json and execute them reliably with the asc workflow CLI, including validation, dry runs, and resumable failures. ## Core Features & Use Cases - Workflow Authoring & Validation: Define workflows with steps, hooks, env vars, conditionals, and JSON outputs, then validate structure before running. - Safe Execution: Preview runs with --dry-run, execute with runtime params, and resume failed runs by run ID without re-entering parameters. - Release Automation: Chain TestFlight distribution, App Store validation, staging, and review submission into repeatable workflows. - Use Case: You need to distribute the latest iOS build to a TestFlight group. Define a beta workflow that resolves the latest build, lists groups, and conditionally adds the build to a group, then run it with asc workflow run beta. ## Quick Start Ask the assistant to validate the repo's .asc/workflow.json file and then dry-run the beta workflow with a build ID and group ID before executing it.
