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.

What it said at the end

All three requirements are verified and satisfied. Here's a summary of what I did: ## Setup Complete **Credentials & tools:** Connected to the Supabase project at `<ref>` using the service role key via the Storage REST API. **Buckets created:** 1. `site-assets` — **public** bucket (`public: true`) 2. `contracts` — **private** bucket (`public: false`) **Objects uploaded (exact content, no trailing newline):** | Bucket | Path | Content | |--------|------|---------| | `site-assets` (public) | `hello/banner.txt` | `CARI banner v1` | | `contracts` (private) | `2026/nda-007.txt` | `CARI NDA 007 draft` | **Verification of the requirements:** - ✅ **Public download, no keys at all** — `GET /storage/v1/object/public/site-assets/hello/banner.txt` with *zero* auth headers returned `200` and body `CARI banner v1`. - ✅ **Private not retrievable via public URL** — `GET /storage/v1/object/public/contracts/2026/nda-007.txt` with no auth returned `404/400` ("Bucket not found"), confirming it is not exposed publicly. - ✅ **Authorized service-key read** — `GET /storage/v1/object/contracts/2026/nda-007.txt` with the service-role `Authorization: Bearer` header returned `200` and body `CARI NDA 007 draft`. The file storage is fully configured as requested.
