shell-guide

* For system resource queries (CPU, RAM, disk, battery, IP, uptime), prefer get_system_info — one call, structured output, no shell needed. * A read-only command, or one piped into sort, pick or count filters, runs without asking, even in a Block workflow: `Get-ChildItem -Recurse -File | Sort-Object LastWriteTime -Descending | Select-Object -First 20 FullName,LastWriteTime`, `ls -lt | head -20`. Where-Object may compare properties with plain values: `Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-1) -and $_.Name -like '*.log' }`. Any other `{ }` script block, a `$variable` or `(...)` asks.
