Individual skill
php
Use when writing, reviewing or modernizing PHP (8.3-8.5) outside Laravel — strict types, union and intersection types, readonly classes, backed enums, property hooks and asymmetric visibility, the pipe operator and clone-with, Composer with PSR-4, PER-CS style, PSR interop, and the quality toolchain (PHPStan, Pint, Rector, PHPUnit/Pest). NOT Eloquent, Blade or Artisan (that is `laravel`).

# Modern PHP (8.x)
Write PHP the way the 2025-2026 ecosystem does: `declare(strict_types=1)` at the top of
every file, typed everything, Composer-first, statically analyzed at the top level — not
the way a 2015 WordPress plugin did. This skill owns the **language and its
framework-agnostic ecosystem**: the type system, Composer + PSR-4, PER-CS style, the PSR
interop interfaces, and the quality toolchain.
**Version targeting.** Floor is **8.3** (security-only, the lowest you should support).
Default new code to **8.4** (property hooks, asymmetric visibility). Use **8.5** features
(`|>`, `clone with`, `array_first`/`array_last`, `#[\NoDiscard]`) only when the deploy
runtime is confirmed 8.5+ — 8.5 released 2025-11-20. 7.x and 8.0-8.2 are EOL; never target
them.
