Cc.Nvim — Development skill for Claude Code

cc.nvim

A neovim-native coding agent wrapper. Works with Claude Code and Codex CLIs. Replaces TUI with a vertical split:

• foldable tree display of chat and tool calls
• editable markdown prompt buffer

Both are native neovim buffers.

Why

• I love neovim and dislike TUIs.
• I just wanted a simple markdown buffer to edit my prompts in, with all the key bindings I'm used to.
• I like the foldable tree as a way of visualizing agent sessions.
• I'm obsessed with customizing my workflows. I hated having little control over the TUI.

Additionally, there were some issues with claude code when I built this, (that may be out-of-date today):

• Scrollback: Since the TUI switched to an alternate screen buffer (#42670, #28077), you can't scroll up to read earlier messages — even ten messages back. And even if you are not facing these issues, the default verbose output includes a lot of tool results, which can quickly overflow your terminal scrollback limit (which helps perf), cutting off the beginning of the session. In a Neovim buffer it's just gg (reliably beginning of session), G (latest message/enter tail mode), / (page up/down), search, marks, yank (with no copy formatting issues caused by trailing whitespace).
• Rendering flicker and redraw jitter. Streaming tokens in the TUI repaint the whole screen; inside tmux this spirals into thousands of scroll events per second (#9935, #3648). cc.nvim appends to a buffer — no alt-screen, no repaint storms.
• Long sessions get sluggish. The TUI holds and redraws the entire conversation from the
