+name: working-with-tmux
+description: Instructions for using tmux to spawn multiple processes, inspect them, and capture their output. Useful for running servers or long-running tasks in the background.
+metadata:
+  source: https://github.com/ampcode/amp-contrib
+---
+
+This skill lets you manage multiple concurrent processes (like servers, watchers, or long builds) using `tmux` directly from the `Bash` tool.
+
+Since you are likely already running inside a tmux session, you can spawn new windows or panes to handle these tasks without blocking your main communication channel.
+
+## 1. Verify Environment & Check Status
+
+First, verify you are running inside tmux:
+
+```bash
+echo $TMUX
+```
+
+If this returns empty, you are not running inside tmux and these commands will not work as expected.
+
+Once verified, check your current windows:
+
+```bash
+tmux list-windows
+```
+
+## 2. Spawn a Background Process
+
+To run a command (e.g., a dev server) in a way that persists and can be inspected:
+
+1.  **Create a new detached window** with a specific name. This keeps it isolated and easy to reference.
+
+    ```bash
+    tmux new-window -n "server-log" -d
+    ```
+
+    _(Replace "server-log" with a relevant name for your task)_
+
+2.  **Send the command** to that window.
+    ```bash
+    tmux send-keys -t "server-log" "npm start" C-m
+    ```
+    _(`C-m` simulates the Enter key)_
+
+## 3. Inspect Output (Read Logs)
+
+You can read the output of that pane at any time without switching your context.
+
+**Get the current visible screen:**
+
+```bash
+tmux capture-pane -p -t "server-log"
+```
+
+**Get the entire history (scrollback):**
+
+```bash
+tmux capture-pane -p -S - -t "server-log"
+```
+
+_Use this if the output might have scrolled off the screen._
+
+## 4. Interact with the Process
+
+If you need to stop or restart the process:
+
+**Send Ctrl+C (Interrupt):**
+
+```bash
+tmux send-keys -t "server-log" C-c
+```
+
+**Kill the window (Clean up):**
+
+```bash
+tmux kill-window -t "server-log"
+```
+
+## 5. Advanced: Chaining Commands
+
+You can chain multiple tmux commands in a single invocation using `';'` (note the quotes to avoid interpretation by the shell). This is faster and cleaner than running multiple `tmux` commands.
+
+Example: Create window and start process in one go:
+
+```bash
+tmux new-window -n "server-log" -d ';' send-keys -t "server-log" "npm start" C-m
+```
+
+## Summary of Pattern
+
+1. `tmux new-window -n "ID" -d`
+2. `tmux send-keys -t "ID" "CMD" C-m`
+3. `tmux capture-pane -p -t "ID"`
