Add file uploads · prompt 4 · Codex CLI · week 2026-W44

Codex CLI built it with @vercel/blob

Prompt: Add image uploads with a drag-and-drop component and hosted storage.

Grader: The agent installed @vercel/blob, wired a handleUpload route and a drag-and-drop UI with progress, previews, and filters, and the build passed. Uploads need BLOB_READ_WRITE_TOKEN, and the agent only verified the not-connected error path, not a real upload.
