What problem does it solve? Writing EAS workflow YAML files for Expo projects requires up-to-date knowledge of job types, triggers, runners, and expression syntax, and mistakes are only caught late without proper validation against the EAS schema and CLI. ## Core Features & Use Cases - Workflow Authoring: Generate and edit .eas/workflows/*.yml files using the live EAS JSON schema as the source of truth for job types, triggers, and parameters. - CLI Validation: Validate workflow files with eas-cli workflow:validate, which checks build profile references against eas.json and performs server-side validation. - Cached Documentation Fetching: Retrieve the schema and syntax docs through a Node.js fetch script with ETag-based HTTP caching. - Use Case: A developer wants a CI/CD pipeline that builds an iOS app on every pull request and submits it to App Store Connect; this Skill generates the workflow YAML and validates it against the project's EAS configuration. ## 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.
