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

All done. Here's the summary: **What I did:** 1. **Created `public.products` table** with columns `sku` (text PK), `name` (text NOT NULL), `price_cents` (integer NOT NULL), `stock` (integer NOT NULL DEFAULT 0) via direct SQL over the DB connection. 2. **Inserted 5 rows** (`CARI-001` through `CARI-005`) with `ON CONFLICT` upsert logic so the operation is idempotent. 3. **Configured Row Level Security (RLS):** - Enabled RLS on the table (Supabase best practice). - Created a **"Public read access"** policy granting `SELECT` to the `anon` role. - Created a **"Service role full access"** policy for admin operations. 4. **Verified the read path** — a `curl` request to the PostgREST endpoint (`/rest/v1/products`) authenticated with **only the anon key** successfully returned all 5 rows.
