A practical how-to for running Claude Code and other long-lived AI coding agents inside tmux, arguing that tmux is the right tool because it survives disconnection, consolidates multiple agents into named sessions, and is fully scriptable from the outside. The built-in claude worktree tmux flag automates the one-agent-per-branch case (claude worktree tmux or claude worktree <name> tmux) but uses iTerm2 native panes by default and requires tmux=classic for real tmux scripting. For multi-agent workflows, manual tmux setup is required: one tmux session per repository (named after the repo), one window per agent (windows for idle agents, panes for the two or three to watch side-by-side), tiled or main-vertical layouts, and attach-or-create session commands like tmux new-session -A -s <name> -c <dir>.
Concrete, actionable specifics cover useful .tmux.conf deltas (large history-limit, tmux-256color, mouse on, allow-rename off, base-index 1, monitor-activity on, escape-time 10, pane-jump bindings), pane creation and layout commands, and the scripting/readback pair: tmux send-keys (use -l to send literal strings, escape trailing ;, sleep before Enter, C-c to interrupt) and tmux capture-pane (use -J to join wrapped lines, -S to pick a range, -e to keep colors). pipe-pane streams raw output to logs. The guide also shows how to turn tmux’s status line into a lightweight monitor of agent activity and documents practical limits encountered when running multiple agents.

OmniPTY is an opinionated terminal emulator for macOS and Linux that features splits, workspaces, a file tree, and an integrated prompt. It is GPU-rendered and written in Rust. (github.com)
Building personal software factories is a waste of time for most developers, as AI tools can accomplish similar goals more efficiently. Instead, focus on learning how AI models work and applying automation to work-related systems for tangible benefits. (peterp.me)
The Free Pascal Compiler and Lazarus IDE now support dynamic packages, enabling quick creation and installation of components and plugins without rebuilding the IDE. This feature enhances flexibility by allowing programs to use replaceable plugins and modules, with some restrictions on unit names and package size. (getlazarus.org)
