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

I have successfully completed the task. Here is a summary of the steps taken: 1. **Created the Table:** Connected via Postgres using the `SUPABASE_DB_URL` environment variable and created the `public.products` table with the requested columns (`sku`, `name`, `price_cents`, `stock`). 2. **Set Permissions:** Granted `SELECT` rights on the `products` table to the `anon` and `authenticated` roles since PostgREST evaluates those database-level permissions when an API call is made. Note that Row Level Security (RLS) is disabled by default on new tables, so granting permissions is sufficient here. 3. **Seeded the Data:** Loaded the five predefined product rows (Anvil S/M/L, Rope 30m, and Pulley) directly into the table. 4. **Verified the Output:** Tested the setup by executing a `GET` request against the `products` endpoint using PostgREST's REST API, authenticated *only* with the `SUPABASE_ANON_KEY`. The read path works beautifully and successfully exposes the 5 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.
