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. Set up file storage: 1) Create a PUBLIC bucket named site-assets and upload a text object at path hello/banner.txt whose content is exactly: CARI banner v1 2) Create a PRIVATE bucket named contracts and upload a text object at path 2026/nda-007.txt whose content is exactly: CARI NDA 007 draft When you are done: the site-assets object must be downloadable by a plain unauthenticated HTTP GET (no keys at all); the contracts object must NOT be retrievable through the public URL pattern, but must be readable in an authorized server-side request using the project's service key.

CARI NDA 007 draft

What it said at the end

I have completed the setup for the file storage exactly as you requested. Here's what I did: 1. **Environment Setup**: Initialized a Node.js project and installed `@supabase/supabase-js` adapted to the current Node.js version. 2. **Bucket Creation**: Used the Supabase Storage API using the `SUPABASE_SERVICE_ROLE_KEY` to create two buckets: - `site-assets`: Specifying the flag `public: true` to allow public object fetching. - `contracts`: Specifying the flag `public: false` to ensure its contents remain private. 3. **Object Uploads**: - Uploaded `hello/banner.txt` with content `CARI banner v1` into `site-assets` bucket. - Uploaded `2026/nda-007.txt` with content `CARI NDA 007 draft` into the `contracts` bucket. 4. **Verification**: Checked both endpoints using `curl`. - Unauthenticated GET requests to the public URL for `hello/banner.txt` are successful and download the file. - Unauthenticated GET requests to the public URL for `2026/nda-007.txt` are rejected (`404 Bucket not found` on the public endpoint). - Authorized GET requests to the standard object endpoint utilizing your initial `SUPABASE_SERVICE_ROLE_KEY` as a Bearer token successfully read the `2026/nda-007.txt` file. Make sure you use the non-public path (`/storage/v1/object/contracts/...`) when providing the authorization headers.

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.
