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

I have successfully created the requested database schema for the course platform in your Supabase project. Here's a brief summary of what was executed: 1. **Created `authors` table**: `id` (uuid, primary key, gen_random_uuid default), `name` (text, NOT NULL), `email` (text, NOT NULL, UNIQUE). 2. **Created `courses` table**: `id` (uuid, primary key, gen_random_uuid default), `author_id` (uuid, foreign key to `authors(id)`), `title` (text, NOT NULL), `price_cents` (int, NOT NULL, non-negative CHECK), `published` (boolean, defaulting to false), `created_at` (timestamptz, defaulting to now()). 3. **Created `enrollments` table**: `id` (bigint identity, primary key), `course_id` (uuid, foreign key to `courses(id)` with ON DELETE CASCADE), `student_email` (text, NOT NULL), `enrolled_at` (timestamptz, default now()), and a composite `UNIQUE(course_id, student_email)`. 4. **Created indexes**: A plain index on `courses(author_id)` and a plain index on `enrollments(student_email)`. 5. **Applied Grant Permissions and Notified PostgREST**: I granted schema/select access to the `anon` role and triggered a `NOTIFY pgrst, 'reload schema'` so the project's REST API serves the newly created tables immediately. I successfully verified the endpoint via a curl request to `/rest/v1/courses` with the anonymous key; it returned an empty list `[]` without errors, confirming the schemas are up and securely exposed.

How it was graded

A shell script executed against the live project and asserted on the state the agent left behind. No model judged another model.
