Set it up in Melso
- 1In Melso, open Settings → Agent Apps and hit Connect on Slack.
- 2Finish the OAUTH2 sign-in in the window that opens. Melso stores the connection, not your credentials.
- 3Open your Codex agent, go to its Agent Apps tab, and allow Slack.
- 4Give the agent a task. It calls Slack itself when the work needs it.
