vps_host_server

Applies per-VPS bandwidth limits using tc/HTB and ebtables following patterns in `tclimit`, `limitbw`, and `run_buildebtables.sh`. Handles vnet interface detection, HTB qdiscs, /tools/bandwidth/{id}/ flag files, and ebtables FORWARD rules. Use when asked to 'set bandwidth limit', 'apply tc rules', 'update ebtables', or run `limitbw`. Do NOT use for OpenVZ/venet traffic shaping (see `vzopenvztc.sh` which uses CBQ, not HTB).

Provisions a new KVM VPS: LVM or ZFS volume creation via vps_kvm_lvmcreate.sh, libvirt XML config from windows.xml, DHCP entry in dhcpd.vps, VNC setup via provirted.phar, and ebtables rebuild via run_buildebtables.sh. Use when asked to 'create a VPS', 'provision KVM', 'add a new VM', or modify install scripts. Do NOT use for LXD, OpenVZ, or Virtuozzo provisioning.

PHP 8.x modern patterns, PSR standards, and SOLID principles. Use when reviewing PHP code, checking type safety, auditing code quality, or ensuring PHP best practices. Triggers on "review PHP", "check PHP code", "audit PHP", or "PHP best practices".

Use when building PHP applications with modern PHP 8.3+ features, Laravel, or Symfony frameworks. Invokes strict typing, PHPStan level 9, async patterns with Swoole, and PSR standards. Creates controllers, configures middleware, generates migrations, writes PHPUnit/Pest tests, defines typed DTOs and value objects, sets up dependency injection, and scaffolds REST/GraphQL APIs. Use when working with Eloquent, Doctrine, Composer, Psalm, ReactPHP, or any PHP API development.

Expert in strict POSIX sh scripting for maximum portability across Unix-like systems. Specializes in shell scripts that run on any POSIX-compliant shell (dash, ash, sh, bash --posix).

Adds or extends a `provirted.phar cron` subcommand invocation in `vps_cron.sh` or `qs_cron.sh`. Understands the cron lock pattern (`/dev/shm/lock`), age-based stale-check with `.cron.age`, `.enable_workerman` flag, and log append to `cron.output`. Use when asked to 'add a cron step', 'schedule a task', 'run something in the vps cron', or modify `vps_cron.sh`/`qs_cron.sh`. Do NOT use for workerman timer-based tasks (setupTimers.php).

Manages libvirt storage pools and LVM/ZFS volumes following create_libvirt_storage_pools.sh and vps_kvm_lvmcreate.sh patterns. Handles virsh pool-define-as, lvcreate/zfs create, pool autostart, and vz pool detection logic. Use when asked to 'create storage pool', 'add LVM volume', 'setup ZFS', or work with /dev/vz/. Do NOT use for image installation, DHCP changes, or network configuration.

Adds a new Workerman event handler or background task following the closure patterns in workerman/src/Events/ and workerman/src/Tasks/. Handles timer registration in setupTimers.php, message routing in onMessage.php, and closure-based stdObject methods. Use when asked to 'add a workerman handler', 'new event', 'background task', or modify workerman/src/. Do NOT use for worker process config (workerman/src/Workers/).
