You're deep in a great Claude Code conversation. You close the terminal. The next day you want to pick up where you left off… and you can't find it. Sound familiar? Let's fix that. Taming Claude Code Sessions · Part 1 of 4 1 2 3 4 🧪 Tested with Claude Code 2.1.x · macOS / Linux What is a “session,” and where does it go? # Every time you run claude, you start a session, one conversation, with its full history. When you quit, that history doesn’t vanish. Claude Code saves it to disk, organized per project folder, here:
If you use tmux, you've hit this: ten windows open and they're all named `zsh` or `node`. Which one had your AI agent running? No idea. Let's make tmux label windows usefully. Taming Claude Code Sessions · Part 3 of 4 1 2 3 4 🧪 Tested with Claude Code 2.1.x · macOS / Linux New to tmux? It’s a “terminal multiplexer”: it splits one terminal into many windows and panes that survive disconnects. The only vocabulary you need here: a window is like a browser tab inside tmux; the bar at the bottom lists them. The prefix is the key you press before a tmux command, commonly Ctrl+b (mine is Ctrl+a). Why everything is named zsh # By default tmux has a setting called automatic-rename turned on. It renames each window after whatever program is running in it. A shell? zsh. A Node program (like Claude Code)? node. Helpful in theory, useless when everything collapses to the same word.
Your development environment should feel like **one cohesive tool**, not a collection of unrelated windows with clashing colors. I theme everything with the same palette: Catppuccin Mocha . The result is a workspace where context-switching between tools is effortless. Why One Palette Everywhere? # Most developers pick a theme for their editor and call it a day. Their terminal is one color, their editor another, their tmux status bar a third, and their Git diffs something else entirely. Every time they switch contexts, their brain spends a fraction of a second recalibrating.
After years of refining my terminal workflow, I've landed on a stack I genuinely enjoy using every day: **Ghostty** as the terminal emulator, **tmux** with **sesh** for session management, and **Neovim** with **LazyVim** for editing. Everything runs on macOS (Apple Silicon) with a consistent Catppuccin Mocha theme across all tools.
I've been gradually replacing classic Unix tools with modern alternatives, mostly written in Rust . After a year of daily use, these aren't experiments anymore. They're muscle memory.
