update-all
Update All
Update all system packages and developer tools in parallel — bringing everything up to date in one command.
Update Tasks
| Task | When to Run | Execution Mode |
|---|---|---|
| winget upgrade | Windows only | ✅ Each package upgraded in parallel |
| Windows Update | Windows only | Serial (scan → download → install → monitor) |
| npm update -g | If Node.js is installed | Single command |
| npx skills update | If Node.js is installed | Check global & project-level |
| sudo apt update → sudo apt upgrade -y | Linux only | ⚠️ Serial (update first, then upgrade) |
All tasks are completely independent and MUST run in parallel. However, some tasks have internal serial steps (apt, Windows Update) — those internal steps must run in order.
Strict Execution Flow
Do NOT use any scripts. Do NOT skip or merge phases. Execute each phase in order.
