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, SUPABASE_DB_PASSWORD. Create a table public.products with columns: sku text primary key, name text NOT NULL, price_cents integer NOT NULL, stock integer NOT NULL default 0. Load exactly these five rows: CARI-001, Anvil S, 1999, 12 CARI-002, Anvil M, 2999, 7 CARI-003, Anvil L, 4999, 3 CARI-004, Rope 30m, 1250, 40 CARI-005, Pulley, 780, 0 The catalog is public: when you are done, an HTTP request to the project's REST API authenticated with ONLY the anon key must return these rows. Confirm that read path works before finishing.

What it said at the end

Created `public.products` with the requested schema and loaded exactly the five specified rows. Configured public read access via RLS policy and granted the `anon` role `SELECT` access. Verified successfully that the REST API returns all five rows using only the anon key.

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.
