What problem does it solve? Writing EAS workflow YAML files by hand is error-prone because job types, triggers, runners, and expression contexts evolve over time, and invalid configurations only surface after a failed run. This Skill fetches the authoritative JSON schema and syntax documentation, then generates and validates workflow files against the real EAS CLI. ## Core Features & Use Cases - Schema-driven generation: Fetches the live EAS workflow JSON schema, syntax docs, and pre-packaged job documentation before writing any YAML, so output always matches current capabilities. - CLI validation: Runs eas-cli workflow:validate on each workflow file, which checks build profile references against eas.json and performs server-side validation. - Use Case: You want a CI pipeline that builds an iOS app on every pull request to main and submits it to App Store Connect. The Skill writes the .eas/workflows/*.yml file with correct triggers, job dependencies, and expressions, then validates it until EAS confirms the configuration is valid. ## Quick Start Ask the assistant to create an EAS workflow that builds your Expo app for Android on every push to main and validate the generated YAML file.
