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

Everything is confirmed working. Here's a summary of what I did: 1. **Created the table** `public.products` with columns: - `sku text PRIMARY KEY` - `name text NOT NULL` - `price_cents integer NOT NULL` - `stock integer NOT NULL DEFAULT 0` 2. **Loaded exactly 5 rows** (CARI-001 through CARI-005) using `INSERT ... ON CONFLICT DO UPDATE` to ensure idempotency. 3. **Enabled Row Level Security (RLS)** on the table and created a `SELECT` policy with `USING (true)` — this allows anyone to read the table (public catalog), while writes still require elevated permissions. 4. **Confirmed the read path** by making an HTTP request to the project's REST API authenticated with **only the anon key** — it returned HTTP 200 with all 5 rows matching the expected data exactly.
