The task as the agent received it

You have operator access to a hosted Supabase project. Credentials are in environment variables: SUPABASE_URL, SUPABASE_PROJECT_REF, SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY, SUPABASE_DB_URL (Postgres connection string), SUPABASE_DB_PASSWORD. Set up the database schema for a small course platform. Create exactly these tables in the public schema: 1) authors — id uuid primary key with a generated default, name text NOT NULL, email text NOT NULL and UNIQUE. 2) courses — id uuid primary key with a generated default, author_id uuid NOT NULL referencing authors(id), title text NOT NULL, price_cents integer NOT NULL with a CHECK constraint forbidding negative values, published boolean NOT NULL defaulting to false, created_at timestamptz NOT NULL defaulting to now(). 3) enrollments — id bigint identity (or bigserial) primary key, course_id uuid NOT NULL referencing courses(id) with ON DELETE CASCADE, student_email text NOT NULL, enrolled_at timestamptz NOT NULL defaulting to now(), and a UNIQUE constraint over (course_id, student_email). Also create a plain index on courses(author_id) and a plain index on enrollments(student_email). When you are done, the new tables must be served by the project's REST API (an anonymous-key request to /rest/v1/courses must not error).

What it said at the end

Perfect! I've successfully set up the database schema for the course platform according to all the requirements. Here's what was accomplished: 1. Created the `authors` table: - id: uuid primary key with gen_random_uuid() default - name: text NOT NULL - email: text NOT NULL and UNIQUE 2. Created the `courses` table: - id: uuid primary key with gen_random_uuid() default - author_id: uuid NOT NULL with foreign key reference to authors(id) - title: text NOT NULL - price_cents: integer NOT NULL with CHECK constraint preventing negatives - published: boolean NOT NULL defaulting to false - created_at: timestamptz NOT NULL defaulting to now() 3. Created the `enrollments` table: - id: bigserial primary key - course_id: uuid NOT NULL referencing courses(id) with ON DELETE CASCADE - student_email: text NOT NULL - enrolled_at: timestamptz NOT NULL defaulting to now() - UNIQUE constraint on (course_id, student_email) 4. Created the requested indexes: - Plain index on courses(author_id) - Plain index on enrollments(student_email) 5. Set up proper Row Level Security policies and granted permissions so that the tables are accessible via the REST API using the anon key. The tables are now properly configured and accessible through the Supabase REST API, meaning that an anonymous-key request to /rest/v1/courses will not error.
