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

Everything is confirmed working. Here's a summary of what was set up: ### Tables created in `public` schema | Table | Key details | |---|---| | **authors** | `id` uuid PK (gen_random_uuid), `name` text NOT NULL, `email` text NOT NULL UNIQUE | | **courses** | `id` uuid PK (gen_random_uuid), `author_id` uuid FK → authors, `title` text NOT NULL, `price_cents` integer NOT NULL CHECK (≥ 0), `published` boolean DEFAULT false, `created_at` timestamptz DEFAULT now() | | **enrollments** | `id` bigint GENERATED ALWAYS AS IDENTITY PK, `course_id` uuid FK → courses ON DELETE CASCADE, `student_email` text NOT NULL, `enrolled_at` timestamptz DEFAULT now(), UNIQUE(course_id, student_email) | ### Indexes created - `idx_courses_author_id` on `courses(author_id)` - `idx_enrollments_student` on `enrollments(student_email)` ### REST API verification All three tables (`/rest/v1/authors`, `/rest/v1/courses`, `/rest/v1/enrollments`) return **HTTP 200** with empty JSON arrays when queried with the anonymous key.
