Agent sign-in and API key entry proposed for the panel

dhh opened omacom/omarchy#16520 to extend the agents panel's add screen beyond Claude Code, Codex and Grok. The open proposal offers nine subscription sign-ins and nine providers accepting pasted API keys, reducing the need to configure supported providers elsewhere.

The proposed key flow passes credentials through standard input, saves them with restricted permissions and restores the previous configuration if a provider rejects a key. The submission reports sandbox and interface checks, but no completed sign-in or key validation against a real service.
