I've been using codecompanion.nvim[0] combined with mcp-hub.nvim[1]. Code Companion works well for interactive chat but falls short for agentic coding. It's limited to some pre-configured and user-defined "workflows" which are basically templated steps with prompts, actions, and loops.
I've been meaning to give avante.nvim[2] a try since it aims to provide a "Cursor like" experience, but for now I've been alternating between Code Companion for simple prompts and Claude CLI (in a tmux pane next to Neovim) for agentic stuff.
Claude Code or cursor-cli or Codex or any of the command-line tools should be good. (Claude Code seems so far to be the option people like best of those, though.)
