This talk showcases a sandbox idea: embedding accessibility metadata directly into GraphQL schemas using custom directives and code generation. This enables clients (Android, iOS, and web) to get accessible defaults from day one.</p>\n<p>We'll cover the directive design, how to expose metadata in generated types, and how frontends like Jetpack Compose or SwiftUI consume it. We'll walk through a practical, low friction approach: adding CI friendly validation that catches common contract regressions before changes ship, such as missing required metadata, invalid values, and template drift.</p>\n<p>You'll leave with schema snippets you can copy & paste, strategies to introduce this in your own APIs, and a blueprint for making accessibility part of your developer experience. A repository with working code examples will be provided.</p>\n",
