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.

Verified: anon-key-only REST read returned exactly the five expected rows.

What it said at the end

Created `public.products` with the requested schema and loaded exactly five catalog rows. Enabled RLS, granted `anon` read access, and added a public SELECT policy. Confirmed the REST endpoint using only the anon API key returned HTTP 200 with exactly the expected five rows.

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.
