Zellij Tab/Pane Skill

Open a tab or pane in zellij -- empty, with a shell command, with a Claude session, or with a GitHub issue.

Decision Tree

Step 1: Container
  "pane"/"panel"/"панель" -> PANE
  "tab"/"вкладка"/default  -> TAB

Step 2: Mode
  nothing to run              -> A (empty)
  shell command               -> B (command)
  Claude prompt/plan/task     -> C (claude session)
  GitHub issue (#N / URL)     -> D (issue dev via start-issue)

Mode A: Empty Tab/Pane

User just wants a new tab or pane, nothing to run.

Tab name: user-specified or shell-HH:MM (e.g. shell-14:35).

TAB

timeout 5 zellij action new-tab --name "$TAB_NAME" || {
  _rc=$?
  echo "Command failed. Diagnosing..."
  if [ -z "$ZELLIJ" ]; then echo "Not in zellij session"
  elif [ $_rc -eq 124 ]; then echo "Timed out -- zellij may be hanging"
  else echo "Unknown error (exit code: $_rc)"
  fi
  exit $_rc
}

PANE

timeout 5 zellij action new-pane || {
  _rc=$?
  echo "Command failed. Diagnosing..."
  if [ -z "$ZELLIJ" ]; then echo "Not in zellij session"
  elif [ $_rc -eq 124 ]; then echo "Timed out -- zellij may be hanging"
  else echo "Unknown error (exit code: $_rc)"
  fi
  exit $_rc
}

Mode B: Command in Tab/Pane

User wants to run a shell command (npm test, make build, etc.) in a new tab or pane.

Tab name: derived from command (e.g. npm-test, make-build). Max 20 chars.

TAB

TAB_NAME="<from-command>"

timeout 5 zellij action new-tab --name "$TAB_NAME" -- $CMD || {
  _rc=$?
  echo "Command failed. Diagnosing..."
  if [ -z "$ZELLIJ" ]; then echo "Not in zellij session"
  elif [ $_rc -eq 124 ]; then echo "Timed out -- zellij may be hanging"
  else echo "Unknown error (exit code: $_rc)"
  fi
  exit $_rc
}

PANE

timeout 5 zellij run -- $CMD || {
  _rc=$?
  echo "Command failed. Diagnosing..."
  if [ -z "$ZELLIJ" ]; then echo "Not in zellij session"
  elif [ $_rc -eq 124 ]; then echo "Timed out -- zellij may be hanging"
  else echo "Unknown error (exit code: $_rc)"
  fi
  exit $_rc
}
