The agent-specific commands remain available as usual: M-x agent-shell-anthropic-start-claude-code M-x agent-shell-openai-start-codex M-x agent-shell-google-start-gemini M-x agent-shell-goose-start-agent Toggling display agent-shell now provides basic control to toggle display of shell buffers: M-x agent-shell-toggle: Toggles display of the most recently accessed agent (per project). agent-shell-display-action: Controls how agent shells are displayed when activated. While agent-shell provides basic display toggling, Calum MacRae offers a comprehensive sidebar package. Check out agent-shell-sidebar.
