What problem does it solve? Building server-side Ruby applications against Appwrite requires knowing the correct SDK patterns for users, tables, storage, teams, functions, and SSR session handling, and mistakes like using deprecated classes or missing permissions cause silent failures. ## Core Features & Use Cases - Full SDK Coverage: Provides working Ruby examples for user management, TablesDB CRUD with typed string columns, Query builders, file storage, teams, and serverless functions. - SSR Authentication: Shows the admin-client/session-client pattern with secure cookie handling for Rails and Sinatra, including email/password and OAuth2 flows. - Permissions & Error Handling: Documents Permission/Role strings, common security mistakes, and Appwrite::Exception handling with common HTTP error codes. - Use Case: A developer building a Sinatra backend needs to log users in via Appwrite, store their data in tables with row-level permissions, and upload files to a bucket, all using the Ruby server SDK. ## Quick Start Ask the assistant to write Ruby code that connects to Appwrite with an API key and creates a table row with read permissions for a specific user.
