customize via `.tmux.conf.local` - Dual prefix support (C-a + C-b for nested sessions) - SSH-aware, Powerline-inspired theming **Essential Plugins** (via TPM): 1. `tmux-plugins/tmux-sensible` — Sensible defaults 2. `christoomey/vim-tmux-navigator` — Vim ↔ tmux seamless navigation 3. `tmux-plugins/tmux-yank` — System clipboard integration 4. `tmux-plugins/tmux-resurrect` — Persist sessions across restarts 5. `tmux-plugins/tmux-continuum` — Auto-save every 5 minutes **Modern Tools** (new in 2025-2026): - **dmux** (Rust) — Workspace manager for multi-agent setups - **sessionx** — FZF session switcher with preview - **sesh** — Intelligent session detection by project type - **treemux** (Rust) — File explorer sidebar (Nvim-Tree style) - **laio** (Rust) — Flexbox-inspired declarative layouts ### Critical Settings for AI Development ```tmux set -g escape-time 0 # Neovim ESC responsiveness set -g history-limit 250000 # Claude Code output volume set -g allow-passthrough on # DEC 2026 synchronized output set -g extended-keys on # Alt key combinations work set -g focus-events on # TUI app focus tracking set -g set-clipboard on # OSC 52 native clipboard set -g status-interval 10 # Reduce CPU (5-10s better than 1s) ``` ### Integration Patterns **Pattern 1: Neovim + Claude Code in Same Session** ``` Window 1: Neovim (with sidekick.nvim, claude-code.nvim) Window 2: Claude Code REPL (separate pane) Window 3: Tests/Monitor (watch build output) Navigation: Ctrl-h/j/k/l (vim-tmux-navigator) moves seamlessly Workflow: Query Claude from Neovim, see response in adjacent pane ``` **Pattern 2: Multi-Agent Autonomous Development** ``` Session: multi-agent-dev ├─ Window 1: Orchestrator (shipwright status) ├─ Window 2: Agent-1 (API backend, git worktree) ├─ Window 3: Agent-2 (UI frontend, git worktree) ├─ Window 4: Monitor (shipwright vitals, cost tracking) └─ Window 5: Memory (failure patterns from last runs) Each agent runs in isolated git worktree, no merge conflicts ``` **Pattern 3: Floating Popups for Quick Tasks** ``` Ctrl+G → Floating scratch terminal (fzf, commands, repl) Ctrl+S → Floating session switcher Ctrl+J → Floating git status Ctrl+F → Floating file search (rg + fzf) Ctrl+P → Floating process monitor Popups don't reshape main layout, press Escape to dismiss ``` ### Performance Characteristics | Metric | Value | Notes | | ---------------------------------- | -------- | ---------------------------- | | Memory (idle session) | 2 MB | Single session, no panes | | Memory (4 panes + 250K scrollback) | 45-60 MB | Typical multi-agent setup | | CPU (idle) | <0.1% | Minimal overhead | | CPU (active with updates) | 0.5-2% | Terminal rendering dominates | | Keyboard latency (C-a key) | <5ms | Instant with escape-time 0 | | Pane switch latency (C-h) | <2ms | Native vim-tmux-navigator | | Status bar update | <10ms | Every 5-10s intervals | ### Hooks Lifecycle Key automation points: - `after-new-session` — Create git worktree, init CLAUDE.md, start memory system - `window-linked` — Auto-rename window to match branch - `pane-exited` — Capture output, check status code, trigger next stage (if gated) - `session-closed` — Save state, cleanup worktrees, post event to heartbeat ### Copy-Mode Best Practices For TUI apps (Vim, Neovim, Claude Code): - Bind vi-style keys: `v` begin, `y` copy, `H`/`L` line bounds - Shift+drag for cross-pane selection (bypasses tmux capture) - Don't use mouse mode in AI workflows (conflicts with tool focus) - On macOS: bind `y` to `pbcopy`; on Linux: bind `y` to `xclip` ### Version Compatibility Matrix | Feature | Min Version | Status | | ------------------------------------ | ----------- | --------------------------- | | `display-popup` (floating windows) | 3.2+ | Full support | | `allow-passthrough` (DEC 2026 sync) | 3.2+ | Eliminates TUI flicker | | `extended-keys` (Alt combinations) | 3.0+ | TUI compatibility | | `focus-events` (app focus tracking) | 2.2+ | Responsive to window events | | `set-clipboard` (OSC 52) | 3.2+ | Native clipboard over SSH | | `if-shell` versioning (`%if` syntax) | 2.4+ | Conditional config loading | | `copy-pipe-and-cancel` | 2.5+ | Enhanced copy behavior | --- ## Research Coverage ### Topics Fully Researched 1. **Core Configuration Patterns** ✓ - Oh My Tmux! framework - Conditional version detection - Override hierarchy 2. **Status Line Best Practices** ✓ - Minimal vs. informative trade-offs - Performance considerations - Neovim-specific optimizations 3. **Advanced Features** ✓ - Hooks (after-new-session, pane-exited, etc.) - Copy-mode for TUI apps - display-popup floating windows - Mouse mode conflicts and resolution 4. **Plugin Ecosystem** ✓ - TPM installation and workflow - Essential plugins (2025-2026) - Modern tools (dmux, sessionx, sesh, treemux, laio) 5. **Neovim + AI Integration** ✓ - vim-tmux-navigator setup - claude-code.nvim, sidekick.nvim, avante.nvim - Multi-agent orchestration patterns 6. **Performance Tuning** ✓ - High-throughput Claude Code scenarios - Memory and CPU optimization - Status bar frequency tuning 7. **CI/CD and Automation** ✓ - Automated session setup scripts - GitHub Actions integration - Shipwright daemon patterns 8. **Hooks & Lifecycle** ✓ - Complete event list - Use cases for each hook - Shipwright integration examples 9. **Copy-Mode Optimization** ✓ - vi-style keybindings - Clipboard integration (macOS, Linux) - TUI app considerations 10. **Mouse Mode Handling** ✓ - On vs. Off trade-offs - Shift+drag for selection - AI tool compatibility 11. **Floating Popups** ✓ - display-popup syntax (3.2+) - Use cases (fzf, git, file search) - Best practices 12. **Conditional Configuration** ✓ - if-shell version detection - %if modern syntax - Platform-specific (darwin, linux) 13. **Session Management** ✓ - One session per project pattern - Tmuxinator and alternatives - Multi-agent git worktree patterns 14. **Shipwright Integration** ✓ - Daemon configuration - Team pane layouts - Vitals monitoring - Cost tracking in status line --- ## Recommended Reading Order **For Quick Setup** (< 30 min): 1.

If you prefer minimal configs, use the templates from TMUX-QUICK-REFERENCE.md section "Minimal Production Config". **Q: How do I integrate with existing Vim/Neovim config?** A: Install `vim-tmux-navigator` plugin via your plugin manager, then add the keybindings from TMUX-BEST-PRACTICES-2025-2026.md section 5.1 to `.tmux.conf.local`. **Q: Can I use this with Shipwright's daemon?** A: Yes! See TMUX-BEST-PRACTICES-2025-2026.md section 8 for daemon-specific configuration, including vitals monitoring and cost tracking in the status line. **Q: What's the minimum tmux version I need?** A: tmux 3.0+ for modern features. For floating popups (display-popup), you need 3.2+. Older versions work but lack advanced features. **Q: How do I handle mouse conflicts with AI tools?** A: See TMUX-ARCHITECTURE.md section 7 and TMUX-BEST-PRACTICES-2025-2026.md section 3.4. Recommendation: keep mouse OFF for AI workflows, use Shift+drag when needed. **Q: How much does tmux actually slow down my terminal?** A: Very little. Most overhead is terminal rendering, not tmux logic. See TMUX-ARCHITECTURE.md section 11 for benchmarks. **Q: Should I set up tmux before or after installing Claude Code?** A: Either order works. Recommend setting up tmux first (basic config), then install Claude Code plugins. They complement each other. --- ## Notes - All configuration snippets have been tested with tmux 3.2+ on macOS and Linux - Plugin versions reflect active maintenance as of February 2026 - Shipwright integration examples assume Shipwright 1.x+ with daemon support - Performance metrics are typical; actual numbers vary by system and workload --- **Document Version**: 1.0 **Last Updated**: February 12, 2026 **Status**: Complete For corrections, clarifications, or additions, refer to the source documents: - TMUX-BEST-PRACTICES-2025-2026.md - TMUX-ARCHITECTURE.md - TMUX-QUICK-REFERENCE.md
