 - *ai-code-interface.el* is built for the second case. Its real advantage is not just backend coverage. Its main advantage is *workflow portability*: the same menu, context gathering, prompt flow, refactoring commands, TDD helpers, review workflow, prompt files, and Emacs MCP tools continue to work while the backend changes underneath.

-- All four packages aim to keep AI-assisted development inside Emacs. The difference is what stays fixed. In =claude-code-ide.el=, the center is Claude Code. In =agent-shell=, the center is the ACP shell session. In =eca-emacs=, the center is the ECA workspace. In =ai-code-interface.el=, the center is your *development workflow inside Emacs*.

 - That distinction matters if you do not want to commit to a single winner forever. You can use Claude Code for one task, Codex for another, Gemini CLI for a third, and still keep the same habits inside Emacs: the same entry points, the same context model, and the same review-oriented development flow. You are changing the backend, not changing how you work.

 *** Q: During using ghostel terminal backend, for long conversation, I found the earliest conversation got truncated
 
 - A: Ghostel trims old output after `ghostel-max-scrollback` bytes are used. The default is 5 MB, so increase it before starting Ghostel sessions.
