What problem does it solve? Writing EAS workflow YAML files requires knowing the current schema, job types, triggers, and expression contexts, which change as Expo ships new features. This Skill fetches the live JSON schema and official docs so generated workflows are accurate, then validates them with the EAS CLI. ## Core Features & Use Cases - Schema-Grounded Generation: Fetches the official EAS workflow JSON schema and syntax documentation before writing or editing files in .eas/workflows/. - CLI Validation: Runs eas-cli workflow:validate on each changed workflow file, checking build profile references against eas.json and EAS server-side rules. - Use Case: A developer wants a CI/CD pipeline that builds an iOS app on every pull request and submits to TestFlight on merge. The Skill generates the workflow YAML with correct triggers, job dependencies, and expressions, then validates it against the linked Expo project. ## Quick Start Ask the assistant to create an EAS workflow that builds your Expo app on every push to main and validate it with the EAS CLI.
