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 adds features. This Skill fetches the official schema and documentation, then generates and validates workflow files against the live specification. ## Core Features & Use Cases - Schema-Driven Generation: Fetches the official EAS workflow JSON schema and syntax documentation before writing workflow files, avoiding outdated assumptions. - Automated Validation: Validates .eas/workflows/*.yml files against the live schema using Ajv, reporting precise errors with allowed values. - Efficient Fetching: Caches schema and documentation responses using ETags and Cache-Control headers to minimize redundant network requests. - Use Case: A developer wants a CI/CD pipeline that builds an iOS app on every push to main. The Skill fetches the current schema, writes the workflow YAML with correct job types and triggers, and validates it before committing. ## Quick Start Ask the assistant to create an EAS workflow file that builds your Expo app on every push and validate it against the official schema.
