Claude Code Filetree

An IDE-style file tree for Claude Code that shows what Claude is doing and where in files

[!NOTE] filetree is a Claude Code **mod**: a plugin of function hooks with its own pane. Mods need **Claude Code 2.1.287 or newer**.

filetree lives in the sidebar on the right, full height and resizable. That needs Claude Code's **fullscreen** layout (`/tui fullscreen`, or `"tui": "fullscreen"` in `~/.claude/settings.json`) and a terminal at least 110 columns wide; tmux keeps Claude Code out of fullscreen unless you turn it on. In the default layout filetree stays hidden instead of sitting above the prompt, and `/filetree` tells you how to switch. Works the same in any terminal; tested in Ghostty, Alacritty and foot.

Tested by hand in the terminal on Linux. macOS, the Code tab of the Claude Desktop app and Windows are covered by `claude plugin test` (see `tests/`) in CI. Mods do not load in WSL sessions of the Desktop app.

Installed it as `filetree@filetree` before the repository was renamed? Nothing to do: that i
