Individual skill
tmux
Manage long-running shell sessions with tmux — start a detached session, run a long task, reattach later, capture output. Use when a task takes longer than a single tool call (build, test, log tail).

tmux new-session -d -s build "npm run build > /tmp/build.log 2>&1"
```
## Check on a session
