Notes in. A checklist back.

Send a selected file to your background agent, download it again, and continue the conversation after reconnecting.

This silent walkthrough uses the browser client connected to a running Codex background agent.

View screenshots: selected notes and checklist ? follow-up after reconnecting.

Try it yourself

1. Pair the browser using a fresh invitation from your running agent.
2. Upload a text file with these notes: verify file checksums; document how to revoke a pairing; check reconnect after a restart.
3. Leave that file checked and ask: “Turn the attached notes into three short checklist items.”
4. Click Download beside the file to retrieve it. The client verifies its SHA-256 checksum.
5. Disconnect, reconnect with the saved pairing, then ask: “What were the three checklist items we just discussed?”

Your pairing keeps its own Codex conversation. Keep the agent computer awake. Read setup instructions to start your agent.
